An Overview of Adobe After Effects

This overview introduces you to the key features of After Effects. If you’re an experienced After Effects user, you may want to scan this overview and then skip to “What’s New in After Effects 5.0.”
After Effects is available in two versions. The Standard version provides the core 2D/3D compositing, animation, and effects tools that motion graphics professionals, Web design­ers, and video professionals need. The Production Bundle version meets the needs of visual effects professionals, and includes all of the tools in the Standard Version plus addi­tional keying, motion control, and distortion tools, audio effects, 3D channel effects, 16­bit-per-channel color, vector paint, and support for network rendering.

Adobe Photoshop
You can transform layered Photoshop images into animations with complete ease. Import Photoshop files as compositions one at a time or in batches. After Effects preserves layers, common layer effects, adjustment layers, alpha channels, transfer modes, vector masks, and more. You can then apply visual effects to color-correct, stylize, or manipulate each layer, and animate these layers over time. Use Photoshop paths as mask or motion points. Move easily between Photoshop and After Effects to complete your work.
When you import a layered Photoshop file as a composition, After Effects retains layers and other key Photoshop settings.
Adobe Illustrator
Want to add first-rate typography or eye-catching graphics to your motion graphics and visual effects? Simply import layered files as compositions one at a time or in batches. Choose whether After Effects preserves the layers or merges them on import. Then resize the Illustrator layers to any resolution without losing detail, and animate them with complete control. Copy paths in Illustrator and paste them in After Effects as masks or motion points. With Illustrator 9 files, you can preserve transparency and transfer modes. In addition, you can continuously rasterize Illustrator layers in both 2D and 3D.
ADOBE AFTER EFFECTS 5.0
Adobe Premiere
After Effects can import Premiere projects as compositions. Each video, audio, and still­image clip appears on its own layer, arranged in the correct time-based sequence in the Time Layout window. You can then manipulate these clips to create the sophisticated effects and animations best produced in After Effects. If you use the After Effects filters included with Premiere 6, those effects and their associated keyframes are also imported. In addition, you can embed a link in the After Effects movies you output so that you can use the Edit Original command in Premiere to open the original project.
Adobe GoLive
When creating a marker in After Effects, you can add a URL link that will be embedded in rendered movies. When these movies are included in Web pages created by applications

An Overview of Adobe After Effects

Powerful masking

Extensive masking capabilities give you extraordinary control in After Effects. You can create, edit, and animate as many as 127 masks on every layer. Draw paths to create trans­parencies or to add new objects to an animation, such as stroked lines—even animate text along a mask path. Combine paths to make unusual shapes using Boolean operations such as Add, Subtract, and Intersect. Rotate and scale masks, and apply opacity settings to make masks appear and disappear over time. Lock masks to protect them from change. You can even copy and paste masks into your compositions from Adobe Illustrator and Adobe Photoshop.
After Effects 5 allows multiple masks per layer; you can edit masks in the Composition window or in Layer windows.

2D & 3D compositing

You can work in either 2D or 3D, or mix and match on a layer-by-layer basis. Use the 3D Layer switch to toggle a layer between 2D and 3D at any time. While both types of layers can move horizontally or vertically, 3D layers can also animate numerous properties— such as z-position, xyz-rotation, and orientation—in 3D space while interacting with lights, shadows, and cameras.
Choose a light type to create a specific look. For example, spot lights provide dramatic lighting effects by pointing a cone of light at the point you define. Unparalleled shadow controls determine whether lights cast shadows when they interact with other layers.
ADOBE AFTER EFFECTS 5.0
Create as many lights as you need, and then adjust and animate each light’s properties, controlling its shadow and illumination. Create as many cameras as you need to produce the results you envision. Enable a Depth of Field setting to automatically change camera focus between foreground and background information. You can then animate camera properties such as zoom and focal length, move cameras in space, and cut between cameras.
User Guide
13
Animate layers, cameras, and lights in 3D space.

Extensive motion controls

For impeccable animations, rely on the powerful motion controls in After Effects. Instantly stagger selected layers over a timeframe with the Sequence Layers Keyframe Assistant. Then add unlimited keyframes to animate any layer attribute, including position, rotation, scale, anchor point, and opacity. Position your layers with subpixel accuracy. Refine the look and movement of your motion paths using roving keyframes. When animating static images, apply Motion Blur to create more realistic movement. Use Time Remapping to make frames stutter, play backward, move in slow motion, or freeze. Create sophisticated anima­tions by defining a parent-child relationship between layers. Use expressions to define rela­tionships between parameters so that you can create procedural-type animations without using keyframes.
14
An Overview of Adobe After Effects
Keyframes
Animate layers by setting keyframes for the layer’s properties at different points in time. Keyframes mark the point in time where you’ve set layer property values. For example, if you want a layer to expand as the clip plays, you would set two or more keyframes containing different scale property values.
Motion Sketch and Smoother
Draw animation paths as easily as sketching with a pencil on paper using the Motion Sketch tool. Simply select the tool and draw the animation path on-screen. Adjust your drawing speed to vary the velocity of the path. After Effects automatically creates the keyframes for you. Then use the Smoother tool to smooth the shape of the path and fine­tune it until the animation moves exactly as you want.

Leading-edge video and audio effects

After Effects delivers powerful, precise tools for creating a limitless range of visual and audio effects. You can stylize, enhance, and manipulate layers using a wide array of effects plug-ins; categories include Blur & Sharpen, Channel manipulation, Distortion, Keying, Perspective, Render, Stylize, Transition, and Audio. Apply an unlimited number of visual effects to every layer, and animate every control. Save your most frequently used effects (including keyframes) as Favorites, which you can apply instantly and share with col­leagues. Expand your effects toolkit even further with numerous third-party plug-ins.
Use the Path Text effect to move text along a Bezier path and animate text attributes such as tracking.
ADOBE AFTER EFFECTS 5.0
In addition to applying a number of audio effects to your footage files, you can change the volume levels of audio layers, preview them at a specified quality, and identify and mark locations. Use the familiar Audio palette to set the volume levels of an audio layer, or use the Timeline window to view the waveform values and apply time remapping.

Flexible media handling

Take advantage of previewing capabilities in After Effects to see results as you work, instead of waiting to render movies. With RAM preview, dynamic preview, intelligent caching, and other preview enhancements, you can specify the quality and speed of your playback to maximize efficiency.
When you’re ready to convert your final composition for playback on the medium of your choice, use the versatile Render Queue to render the composition into a finished movie. If you’re using the Production Bundle version, you can render using a network of computers.

An Overview of Adobe After Effects
RAM Preview
One of the big challenges in designing motion graphics and visual effects is imagining how they will look in their final form. Playback controls help, but they don’t really capture the final experience. That’s what makes the RAM Preview feature so exciting. You can play back your compositions in real time without having to render them. You can even preview audio along with the video. If you like the segment that you played back in RAM Preview, you can save it to a file directly.
RAM Preview lets you play a preview at the frame rate of your composition, or as fast as your system allows.
To improve performance, you can narrow the region of interest in the Composition window so that only the specified area of your composition is previewed.
Dynamic preview
Get better visual feedback as you work in the Composition window. Instead of defaulting to a wireframe view when you move, rotate, scale, or otherwise change elements in a composition, After Effects transforms layers interactively, displaying results as you make changes. If the image can’t be updated quickly enough, After Effects temporarily reduces image resolution to maintain optimal interactivity.
ADOBE AFTER EFFECTS 5.0
Intelligent caching
When you view your work in the Composition window—either by scrubbing along the timeline or using the RAM Preview option—After Effects stores, or caches, frames in mem­ory. Cached frames are saved until you make an edit to the composition that renders them obsolete, allowing for faster previews. For example, changing a single keyframe now causes only cached frames between the keyframe you modified and adjacent ones to be invalidated. A green bar beneath the time scale in the Timeline window indicates cached frames.
Resolution independence
You can mix file resolutions from tiny thumbnails up to 30,000-x-30,000-pixel frames within a composition. For example, you could import a high-resolution Adobe Photoshop image into a lower-resolution composition to create a panning background. When you’re done, you can output files at any resolution—from the small sizes preferred for animated GIF files to the high-resolution output required for film.
Render queue
Using the Render queue, you can prepare your files once and then output them to film, video, multimedia, or the Web with equal ease. Perform multiple renders of a composition in various sizes and formats simultaneously, or batch-render any number of different compositions. You can even save render templates for future use.
User Guide
17
In addition, the Collect Files command helps you gather files for rendering or archiving. This command automatically copies a project and all of its associated source footage to a single location, along with a report that lists the footage, effects, and fonts necessary to render the project.

An Overview of Adobe After Effects

Web delivery

After Effects includes several features that optimize output for Web delivery, including Mac­romedia Flash support, embedded URLs, audio compression, and QuickTime streaming.
Macromedia Flash (SWF) support
Export compositions, including audio, as compact, vector-based Flash (SWF) files for use on the Web. You can control whether effects are rasterized as JPEG frames or ignored; you can also generate an HTML report that provides details on the elements that were skipped.
Embed URLs in Web output
Create URL flips in exported Flash files and QuickTime movies by associating an embedded URL with a layer marker.
Audio compression
Both QuickTime and MP3 audio compression codecs are now supported, so you can create files that are even quicker to download on the Web.
QuickTime streaming
Instead of using the After Effects Render Queue, you can export items using components provided by QuickTime. With this QuickTime support, you can prepare streaming video and audio for Web distribution and export AVI files on Windows and Mac OS platforms. If you install new QuickTime export components as they become available from Apple or other third parties, those modules appear on the File > Export submenu in After Effects.
ADOBE AFTER EFFECTS 5.0

Production Bundle features

To meet the needs of different audiences, After Effects is available in two versions—the Standard version and the Production Bundle version.
Visual effects
After Effects offers a variety of exciting types of visual effects including Warping and Particle Playground. You can warp images over time using Bézier Warp, Mesh Warp, and Reshape effects; displace pixels from one layer to another using Displacement Map; or apply the Glow effect to create a diffuse halo along an object’s edge. With Particle Playground, you can animate a large number of objects (dots, images, or text) so that they move independently and yet produce consistent group behavior. Use Fractal Noise to create textures and objects that cannot be described using simple geometric shapes. Other effects include Corner Pin, Lightning, Scatter, Ripple, Bulge, Wave Warp, Optics Compensation, and Twirl.

An Overview of Adobe After Effects
Keying effects
The Production Bundle of After Effects delivers sophisticated keying controls for producing precise composites. The Linear Color Key uses the RGB, hue, or chroma information you specify to create transparency from a key color. With the Color Difference key, you can produce combination mattes to control hard-to-key images such as smoke, shadows, or glass. The Spill Suppressor makes it easy to remove key-color traces from light reflecting off a screen and onto your subject. Create clean mattes with the Simple Choker, or choke and spread the matte to create clean edges with the Matte Choker. The Inner/Outer Key effect makes it easy to extract an object from its background. And you can perform other special­ized keying tasks with the Extract, Difference Matte, Color Range, and Alpha Levels keys.
After Effects color keying lets you isolate objects from a colored background for compositing with different layers.
Motion tools
From reducing unwanted motion to creating natural-looking zoom effects, After Effects delivers the tools you need to produce the highest-quality animations. Use the Motion Tracker to isolate a moving element on one layer and precisely track it to a moving element on another layer. The Motion Stabilizer tracks a single element on a layer to stabilize unwanted motion. With the Wiggler, you can simulate more realistic motion by adding random changes to any property over time.
ADOBE AFTER EFFECTS 5.0
Automate the creation of motion and effects by writing custom scripts with the Motion Math tool—or run the Motion Math scripts included with After Effects. You can even simulate the accelerating effect of a zoom lens using the Exponential Scale tool, which converts linear scaling of a layer to exponential scaling.
Audio effects
The Production Bundle expands the range of high-quality audio effects you can incor­porate into a composition. Add depth and character to a sound with Flange, or make one voice or instrument sound like many with Chorus. Apply Parametric EQ to isolate and fine­tune specific ranges of sound. With Reverb, simulate a spacious, acoustically live interior. Create simple tonal sounds (such as a doorbell) by applying Tone, or use Modulator to precisely control audio delay and modulation, creating echo and chorus effects. You can also enhance sounds by removing high and low frequencies with the High-Low Pass filter.
3D Channel effects
Use the 3D Channel effects to create effects with the auxiliary channel information stored in imported 3D files, including RLA, Softimage PIC/ZPIC, and ElectricImage EI/EIZ files. Use the Depth Matte effect to read the z-depth information in a 3D file, and then slice the image along the z-axis to insert other objects. The Depth of Field Blur effect simulates a camera that focuses on one area in a 3D scene while allowing other areas to blur. The ID Matte isolates objects in a 3D scene for editing. The 3D Fog effect applies a fog effect along the z-axis, so that distant parts of a 3D scene look hazier or even disappear. The 3D Channel Extract effect makes auxiliary channels visible as either grayscale or multichannel color images, which you can use as image maps or in other specialized effects.

Render Engine
Take advantage of network rendering using the Render Engine, which includes an unlim­ited license. Install multiple copies to streamline your rendering process. Each Render Engine can monitor a Watch folder on a network. If you use the Collect Files command to copy projects (and their associated footage) to this Watch folder, each Render Engine starts rendering those projects as soon as they appear. You can monitor the progress using a stan­dard Web browser.
When you save an After Effects project to a Watch folder, multiple computers can render individual frames and compositions of the project.
16-bit-per-channel color
Deep color support means that you get higher-quality output. After Effects 5.0 can work in 16-bit-per-channel mode, making a larger range of colors available. And when you work with high-resolution images that use a narrow range of colors, such as when you’re creating film effects or output for HDTV, the difference is easily visible: transitions between colors are smoother with less visible banding, and more detail is preserved.
ADOBE AFTER EFFECTS 5.0
You can choose whether to work in 8-bit-per-channel or 16-bit-per-channel color mode for each project. You can directly import 16-bit images, including those from Photoshop, and you can composite and color-correct footage in 16-bit mode; the Info palette displays 16­bit color values with exact precision. To optimize performance, quickly rough out a compo­sition in 8-bit color mode, and then finalize and output 16-bit files for maximum quality.
Vector paint tools
The nondestructive vector paint tools in After Effects 5.0 open up a host of new creative pos­sibilities, from strokes that reveal an image over time to animated cartoons and painted tex­tures that change from frame to frame. Use brush controls to specify exactly how the strokes you paint will look. Characteristics such as brush radius, color, and opacity can be modified to get the exact desired look. Use the Onion Skin mode to paint strokes frame by frame. Take advantage of numerous options to control how the paint strokes interact with the layer they appear on. For more control over the final results, you can also choose whether strokes con­tinuously paint or are recorded to the current frame, to sequential frames, or in real time.

What’s New in After Effects 5.0

After Effects is a powerful upgrade to the award-winning motion graphics and visual effects software. Its versatile and powerful new features enable a flexible workflow tailored to your needs.

Precise control

New features such as 3D compositing, layer parenting, vector paint tools, and expressions open creative possibilities. Masking enhancements and dozens of new effects offer creative control.
3D compositing
Built-in support for 3D compositing means you can add new depth to your creative ideas. Mix 2D and 3D layers in a single composition, create and animate lights and cameras, define shadow characteristics, control how 3D layers interact with light sources, and much more.
27
Parenting
Animate layers hierarchically by defining a parent-child relationship between any two layers. The child layer automatically inherits all of the transformations applied to the parent.
Vector paint tools (Production Bundle only)
Use nondestructive vector paint tools to reveal an image over time, draw animated cartoons, and much more. Select brush options; choose whether strokes are recorded to the current frame, to sequential frames, in real time, or continuously; and specify how strokes are played back. Wiggle controls make it easy to create a hand-animated look or a variety of special effects.
28
What’s New in After Effects 5.0
Expressions
Define relationships between parameters to create procedural animations without using keyframes. You can now link the behavior of one property in a composition to almost any other property on any other layer—a powerful new capability that’s also easy to use. You can also use JavaScript to modify expressions.
New effects
After Effects 5.0 includes powerful new effects that offer new creative options. Use the Shatter effect to extrude a layer into 3D space and then demolish it in a variety of ways. Create radio waves, pond ripples, and the like with the Radio Waves effect. Easily extract an object from its background with the Inner/Outer Key effect (Production Bundle only). Use the Vegas effect to outline elements with casino-style running lights or flashes. Create compositions that pulse with color using the Colorama effect. Simulate organic backgrounds and create fractal-based displacement maps, textures, and mattes with the Fractal Noise effect (Production Bundle only). Add or remove lens distortions with the Optics Compensation effect (Production Bundle only).
Masking enhancements
Create masks on the fly by drawing them directly in the Composition window, assign colors to masks for easy identification, and use the new Mask Expansion property to adjust the inner or outer feather of a mask by insetting or outsetting the mask edge from the mask shape.

Enhanced productivity

Smart performance enhancements mean that creating and refining your work is faster than ever. Dozens of interface enhancements introduce significant improvements that provide a more efficient and streamlined workflow. Plus, After Effects delivers tighter integration with Photoshop, Illustrator, and Premiere.
ADOBE AFTER EFFECTS 5.0
Intelligent caching
When you make changes to a composition, only the cached frames affected by the edit are invalidated—so only those frames need to be re-rendered when you preview the compo­sition. This uses RAM more efficiently and results in much faster previewing. A thin green bar beneath the time scale in the Timeline window indicates cached frames, so you can see at a glance how many are currently cached.
Dynamic previews
After Effects now previews layers interactively so you see results as you make changes. To maintain optimal interactivity, After Effects may temporarily drop image resolution.
Improved RAM Previews
Define a Region of Interest that displays just a portion of the composition in order to create longer previews more quickly. View RAM Previews in the Footage and Layer windows or in full-screen mode; specify whether to preview a continuous loop, a single segment, or a palindrome; and define two different sets of RAM Preview options to get the preview quality most relevant to your work.
User Guide
29
Enhanced integration with Adobe software
Work with vector masks and preserve 16-bit color info when you import Adobe Photoshop 6 files. When you import Adobe Illustrator 9 files using the PDF file format, transparency settings and transfer modes can be preserved. Embed a link in the After Effects movies you output so that you can use the Edit Original command in Adobe Premiere to open the original project.
Property values are scrubbable hot text
Enter values directly in the Timeline and Effects Control windows or scrub across a value (scrub hot text) to interactively preview property value settings.
Unified Import dialog
Use a single dialog box for footage, projects, multilayered Photoshop and Illustrator files, and more.

More flexible composition settings
Specify a different starting timecode for each composition, and save frequently used composition settings as custom presets. Specify Motion Blur shutter angles up to 720 degrees and set phase controls that determine when the shutter opens relative to the start of each frame.
Streamlined media management
Manage complex projects with ease. The order in which you select footage in the Project window now determines the stacking order of layers when you drag items to the Timeline window, and you can now drag footage into position in the layer stacking order or on the timeline. Use the new Find command to locate source files in the Project window, and the new Reveal command to locate source files on disk. Clear unused source files and compo­sitions from the project with the Reduce Project command, and shrink the duration of a composition to the current work area with the Trim Comp to Work Area command.
New editing tools

Chapter 1: Working with Projects, Windows, and Palettes
dobe After Effects is a powerful tool for 2D and 3D compositing, animation, and visual effects. You can composite layers in a variety of ways, apply and combine sophisticated visual and audio effects, and animate both objects and effects.
A
In After Effects, every animation starts as a project—a collection of digital video footage, still images (such as Adobe Illustrator or Adobe Photoshop files), and audio files, which you arrange in compositions within the project.

Working in a project

An After Effects project is a single file that stores references to all the footage you use in that project. It also contains information about how you’ve arranged the footage in composi­tions, including the details of any effects or animation you applied. Inside a project, you create one or more compositions. After you have imported source footage into the project, you can add footage items into the compositions.
35
Where you work with footage items
In a project, you work with footage items using primarily three windows: the Project window, which lists all the source footage items you import; the Composition window,
which displays images as they relate in space; and the Timeline window, which displays compositions and animation events in terms of time. Add footage items to a composition by dragging them from the Project window into either the Composition window or the Timeline window.
CHAPTER 1
36
Working with Projects, Windows, and Palettes
Each Composition window has a corresponding Timeline window. When you edit a composition in a Composition window, After Effects automatically displays the corre­sponding Timeline window, and vice versa.

D
C
As you work with compositions, you also use three other types of windows: Footage windows, Layer windows, and Effect Controls windows.
Footage windows are useful for viewing and evaluating footage items in their original
form (see “Viewing imported footage” on page 93).
To view a layer’s original source independently of other layers or to trim footage, you can
open a Layer window (see “Composition, Layer, and Footage window controls” on page 53).
As you work with effects, you use the Effect Controls window to modify and animate the
effects (see “Working with effects” on page 269).
When you render your compositions into a movie, you work in the Render Queue window to select rendering options and queue compositions for rendering (see “Using the Render Queue window” on page 355).
ADOBE AFTER EFFECTS 5.0
How you start a project
Starting a project involves two tasks: (1) planning your project based on the formats of the final output and (2) creating a project file. Once you have planned your project and learned how to perform some basic tasks related to working in After Effects, you’ll be ready to start importing footage (see “Importing files into a project” on page 68). You then create a composition and begin working with your source footage (see “Working with imported footage” on page 93).

Planning your project

Planning your project before you start importing footage makes your work easier. A large part of planning is simply determining the best settings for your source footage based on the media for which you will render your finished project. This step is essential to achieving optimal image quality. Rendering order and nesting may also be part of project planning (see “Organizing a project using nesting” on page 342).
Choosing the right media
Before you start importing footage items into your project, decide which media you’ll use for your finished movies. Then determine the best settings for your compositions and source material. For example, if you will be rendering your project to videotape, create footage at an image size, color bit-depth, and frame rate that will produce the best image quality on videotape. Likewise, if your project is intended for streaming video on the Web, the image size, color bit-depth, and frame rate may need to be reduced to work with the data-rate limits of streaming video on the Web. However, any footage item that can be imported can be used in any composition.
User Guide
37
If you will be rendering a project to more than one media format, always match the resolution setting for your composition to the highest resolution setting used for your output. Then set up the Render Queue window to render a separate version of the project for each format.
CHAPTER 1
38
Working with Projects, Windows, and Palettes
For film and video, try to match import and composition settings with settings in the output module used to render a movie. For example, to ensure smooth playback, the footage frame rate selected in the Interpret Footage dialog box should match the setting in the Composition Settings dialog box and the output module in the Render Queue window. Also, the composition-frame size should be determined by the image size in the playback medium. However, any footage item that can be imported can be used in any composition. See “Preparing motion-footage frame rates for final output” on page 84, “Understanding basic composition settings” on page 103, and “Changing output module settings” on page 361.
If you will be mixing source footage with different pixel aspect ratios, correctly specify this ratio for each footage item in the Interpret Footage dialog box. See online Help.
The suggestions that follow will help you select composition settings. However, the best way to ensure that your project is suitable for a specific medium is to make a test compo­sition and view it using the same type of equipment your audience will use to view it.
Film If you will be rendering for film, consider both the aspect ratio of the frame size you
select for your composition and the frame rate of your source footage. For footage that was transferred from film to video using the 3:2 pulldown telecine method, you must remove 3:2 pulldown before adding effects. See “Removing 3:2 pulldown from video transferred from film” on page 87.
CD-ROM When you create a movie that you plan to render for playback from a CD-ROM,
you may need to specify import and composition settings that take into account the wide range of hardware that your audience may be using, possibly including older single- or double-speed CD-ROM drives.
To make your final output compatible with older CD-ROM drives, try to reduce the data­transfer rate of your final output by specifying certain settings for footage items:
Lower the frame rate as far as you can in the Composition Settings dialog box without
making motion seem too jerky. Start at 15 frames per second (fps).
When rendering your final composition, choose a file type and compressor/decom-
pressor (codec) appropriate for the final media. For example, for a cross-platform CD­ROM, you might specify a QuickTime codec or a codec designed for low data rates, such as Indeo, Cinepak, or Sorenson Video. Regardless of which codec you select, however, it must be available on the system used by your intended audience to ensure successful playback. Also consider the key frame rate of the codec you have selected. See the Adobe Web site for more information on QuickTime compressors and codec key frame rates.
ADOBE AFTER EFFECTS 5.0
Videotape If your final output will be videotape, set up your composition with a specific
video format in mind, such as NTSC or PAL. Using broadcast-safe colors and maintaining frame size and compression ratios are also important considerations. These guidelines will help in setting up a composition intended for videotape:
Select a frame size in the Composition Settings dialog box that matches the frame size of
the destination video format.
Use only NTSC-safe colors when adding or changing color in a project.
If you will be using an MJPEG codec, keep in mind that the frame sizes and resolutions
available for rendering are determined by the specific MJPEG board you are using. Refer to the specifications for your MJPEG board.
Animated GIF When you render an animated GIF, colors are dithered to an 8-bit palette.
Before rendering your final project, render a test composition so that you can adjust colors if the results are not what you expected. If any source footage includes an alpha channel, be sure that you know how it will affect your final project before you start rendering.
Streaming video over the World Wide Web Streaming video resembles a conventional
television signal in that video is sent to the viewer frame by frame, instead of by downloading a large file to the hard disk. Streaming video on the Web is constrained by the limited bandwidth (56 Kbps or less) of most consumer modems, which is even lower than those used for CD-ROM playback. Use the same techniques that are listed for CD­ROM playback, but adapt them for further reduction in file size and data-transfer rate. You can export QuickTime streaming directly from After Effects. See “Exporting footage using QuickTime components” on page 369.
User Guide
39
Downloading video over the World Wide Web If your final output will be downloaded as
a file from the World Wide Web, the main concern is the size of the file, which directly affects how long it takes to download the file. QuickTime and Microsoft Video for Windows are formats often used when rendering final output that will be downloaded. When you render a QuickTime movie, After Effects automatically creates a movie that can play on both Windows and Mac OS without modification.
Intranet playback An intranet is an in-house or private network that uses Internet
network protocols. Intranets generally use higher-quality communications lines than standard telephone lines, so they are usually much faster than the Internet. The data­transfer rate for playback can be 100K per second or faster, depending on the speed of your intranet.
CHAPTER 1
40
Working with Projects, Windows, and Palettes
Flash (.swf) files When you export compositions as Flash (.swf) movies, After Effects
maintains vectors as much as possible. However, some items cannot be represented as vectors in the Flash file. See “Exporting to Macromedia Flash (SWF) format” on page 365.
Considerations for cross-platform projects
After Effects project files are compatible with both the Mac OS and Windows platforms. You can do several things to ease the process of exchanging projects between platforms.
Project hierarchy When you move a project to a different computer and open it, After
Effects attempts to locate the project’s footage files, first looking in the folder in which the project file is located, second using the file’s original path or folder location, and third searching the root of the directory where the project is located.
If you are building cross-platform projects, it is best if the full paths have the same names on Mac OS and Windows systems. If the footage is on a different volume than the project, make sure that the appropriate volume is mounted before opening the project, and that network volume names are the same on both systems.
It helps to store footage in the same folder as the project file or in another folder within that folder. Here's a sample hierarchy:
c:\newproject\project_file.aep c:\newproject\source\footage1.psd c:\newproject\source\footage2.avi
The newproject folder can then be copied in its entirety across platforms, and After Effects will properly locate all of the footage.
File-naming conventions When possible, name your footage and project files with
Windows-compatible filename extensions, such as .mov for QuickTime movies and .aep for After Effects projects. If files will be used on the World Wide Web, be sure that filenames adhere to the appropriate conventions for extensions and paths.
Mac OS file types On Mac OS systems, footage files should have proper Mac OS file types.
Using services for Macintosh in Windows NT Server or Windows 2000 Server, you can set up explicit extension-to-file-type mappings; see the system’s server documentation. If footage files are not properly recognized on Mac OS systems, select All Files for Show in the Import File dialog box to override the Mac OS file types. To open a Windows project on a Mac OS system, the project must have the correct .aep extension.
ADOBE AFTER EFFECTS 5.0
For a list of common extensions and their associated file types, see the Adobe Web site.
Resources Ensure that all resources are available on both systems. Resources can include
fonts, effects, and compressors.

Time basics

Time is central to many operations in After Effects. You can view, specify, and manage time in various ways. Whichever way you handle time, there are several specific time concepts you should understand as you create a project.
Time display
The way you view and specify time in After Effects depends on the display style, or unit of measure, that you use to describe time. By default, After Effects displays time in Society of Motion Picture and Television Engineers (SMPTE) timecode: hours, minutes, seconds, and frames. You can change to another system of time display, such as film frames, or feet and frames of 16mm or 35mm film. See “Setting time-display options” on page 42.
User Guide
41
Video-editing workstations use SMPTE timecode that is often striped (encoded) onto videotape for reference. If you are creating video that will be synchronized with video that uses SMPTE timecode, use the default timecode display style.
Frame rate
Each composition you create can have its own frame rate. The frame rate is the number of frames the rendered composition produces in every second when played back. The frame rate you use is generally determined by the type of output you will produce. For example, video for NTSC television plays at 29.97 frames per second (fps), and PAL plays at 25 fps.
When you set up changes over time, After Effects treats the changes as continuous throughout a composition timeline. Each frame is rendered as a slice out of the timeline at the frame rate you specify. Because After Effects treats time continuously, it is possible to change a composition’s frame rate at any time or override the frame rate of a compo­sition when you render the final movie. See “Setting frame rate” on page 105.
CHAPTER 1
42
Working with Projects, Windows, and Palettes
NTSC (29.97) drop-frame timecode
When you work with a composition that is set to a frame rate of 29.97 fps, After Effects uses SMPTE 30-fps drop-frame timecode by default, making adjustments using the SMPTE-standard method of renumbering the first two frame numbers of every minute, except at every tenth minute. For example, the frame after 59:29 is labeled 1:00:02 instead of 1:00:00. Non-drop-frame timecode is also available. In both cases, frames are not discarded or skipped; they are merely numbered differently.
After Effects displays drop-frame timecode by using semicolons between the numbers and displays non-drop-frame timecode using colons between the numbers. In the Project Settings dialog box, you can choose how 29.97-fps compositions and footage display their timecode. See “Setting time-display options” on page 42.
Duration
Each video footage item, layer, and composition in a project has its own duration. Duration determines the beginning and ending times of the timelines in the Footage, Layer, and Timeline windows. It is important to notice which duration you are viewing while you edit in multiple windows. See “Understanding trimming” on page 139 and “Positioning a layer in time” on page 132.
Frames and fields
Each frame in an interlaced video source is made up of fields. It’s important not to confuse frames with fields. For video, every frame contains two interlaced fields. If you want to use interlaced video as source footage, you’ll usually want After Effects to separate the interlaced fields. Separating fields ensures maximum image quality when you apply animations and effects to video that was originally interlaced. If you’re producing a movie for videotape, you can render the composition to fields in a process known as field-rendering. See online Help and “Field rendering” on page 87.
Setting time-display options
After Effects supports several methods of measuring and displaying time. The method you choose applies to time display in the current project and in any subsequent project you create. Changing the method does not alter the frame rate of footage or a composition— it changes only how frames are numbered. You can choose from three time-display options:
ADOBE AFTER EFFECTS 5.0
Timecode, which counts frames in frames per second (hours, minutes, seconds,
frames).
Frames, which counts frames of footage without reference to time.
Feet and Frames, which counts feet of 16mm or 35mm motion-picture film, and
counts fractions of feet in frames; 35mm film has 16 frames per foot, and 16mm film has 40 frames per foot.
ABC
A. Timecode B. Frames C. Feet and Frames
When working with footage digitized from NTSC video, you usually use the 30-fps, drop­frame timecode base. This counts NTSC-created frames using standard drop-frame timecode for maximum device compatibility. For frames (or feet and frames) timecode, you can also change the starting frame number to match the time-counting method of another editing system you may be using.
User Guide
43
To change the time display:
1 Open the project and choose File > Project Settings.
2 Select a time setting:
To use timecode, click Timecode Base, and then select a frame rate from the Timecode
pop-up menu.
To use drop-frame time code for footage and compositions with a frame rate of 29.97

Setting up a project

After you create a new project, you import footage into the project. You can also specify project settings or application-wide preferences.
Creating a new project
By default, After Effects opens a new Project window when you start the application. When you know the media for your final project, you are ready to create a project by importing your footage items into a new Project window. You can also open a new Project window at any time from the File menu. See “Working with the Project window” on page 51.
To create a new project after closing the current project in After Effects:
Choose File > New > New Project.
Importing footage items
When you import a footage item, After Effects creates only a reference to the file and does not copy or move the file itself. These references to your source files are displayed in the Project window.
To import source footage items into an After Effects project:
1 Choose File > Import > File or Multiple Files.
2 Locate and select footage files and click Open.
For details, see “Importing files into a project” on page 68.
ADOBE AFTER EFFECTS 5.0
Opening and closing a project
You can have only one project open at a time. If you try to open another project, After Effects prompts you to save changes in the first project, and then closes the first project. Closing the Project window closes any associated windows, but palettes remain open.

Correcting mistakes

If you change your mind or make a mistake, undo your work. You can undo only those actions that alter the project; for example, you can undo an edit, but you cannot undo scrolling a window. Specify the number of levels that can be undone. The default is 20. Specifying more levels increases memory requirements but may not affect performance.
Note: The Vector Paint effect (PB only) can perform only one level of undo, regardless of the number of levels you set.
You can also discard changes by reverting to the last saved version of the project. Note that when you revert to the last saved version, all editing and footage imported since you last saved are lost. You cannot undo this action.
To undo the most recent change:
Choose Edit > Undo. You can sequentially undo as many as 99 of the most recent changes made to the program in any After Effects window, depending on how many undo levels are set in Preferences.
To set the number of undo levels:
1 Choose Edit > Preferences > General.
2 Specify a number for Levels of Undo, and then click OK.
To revert to the last saved version:
Choose File > Revert.

Selecting 16-bpc color depth (PB only)

After Effects can work in 16-bit-per-channel mode, making a larger range of colors available. When you work with high-resolution images that use a narrow range of colors, such as when you’re creating subtle gradients for film effects or HDTV output, transitions between colors are smoother with less visible banding, and more detail is preserved.
ADOBE AFTER EFFECTS 5.0
You can choose whether to work in 8-bit-per-channel or 16-bit-per-channel color mode for each project. Directly import 16-bit images, including those from Photoshop, and composite and color-correct footage in 16-bit mode. Take advantage of 16-bit color when performing most After Effects tasks, including layer adjustment, frame blending, 3D, and Cineon file import. The Info palette displays 16-bit color values with exact precision.
Many effects support 16 bits per channel. If an effect supports only 8 bits, and your project is set to 16 bits, After Effects displays a warning icon ( ) next to the effect name in the Effect Controls palette. Using an 8-bit effect in a 16-bit project will result in a loss of detail for the effect’s layer.
When rendering to output module depths of Trillions of Colors, set the project to 16-bit color depth to take advantage of the output file’s extra color precision. To optimize perfor­mance, rough out a composition in 8-bit color mode, and then finalize and output 16-bit files for maximum quality.
To specify color depth:
1 Open the project and choose File > Project Settings.
2 For Depth, choose 8 bits per channel or 16 bits per channel, and then click OK.
User Guide
47
Hold down Alt (Windows) or Option (Mac OS) and click the color depth indicator at the bottom of the project window to toggle between 8- and 16-bits per channel color.

Setting preferences

When you start After Effects for the first time, the default settings are used. You may want to change some of these default settings so that each time After Effects is opened, it uses your selections instead of the standard defaults. After changing settings, you can easily restore the default settings at any time. All After Effects default settings are stored in a single file.
After Effects saves the location and type of each open window with the project. Palette positions are saved in the After Effects Preferences file, which applies to all projects. You can also save custom workspaces; see “Customizing the workspace” on page 48.
To open a preferences dialog box:
1 Choose the preferences command you want from the Edit > Preferences submenu.

Using windows

Many After Effects windows are organized in groups by default. You can customize and display these windows in certain ways depending on the type of window:
Composition window The title of a Composition window appears as a tab under the
group window’s title bar. By default, Composition windows are grouped into one window. You can combine Composition windows with Layer and Footage windows.
Layer and Footage windows As with Composition windows, the title of a Layer or
Footage window appears as a tab under the group window’s title bar. By default, Layer and Footage windows are grouped into one window. They can also be combined with the Composition windows and other Layer and Footage windows.
Timeline windows Each composition name appears as a tab in the Timeline window. You
can combine Timeline windows only with other Timeline windows.

Use the Composition, Layer, and Footage windows to preview and edit different parts of a project. These windows share a set of controls that you can use to view safe zones (the visible areas of a television screen), view RGB and alpha channels, and change the magni­fication. These controls function the same way in all three windows.
Displaying After Effects viewing controls in the Footage window
By default, the Footage window displays movie controls for movie footage rather than the After Effects viewing controls found in the Layer and Composition windows. QuickTime and Video for Windows controls are fast and familiar tools for playing movie footage, and they play audio if it’s included in the footage. However, for the preview options discussed in this section, you must open the footage in a standard After Effects Footage window.
User Guide
53
Note: A standard After Effects Footage window is always used for non–QuickTime and non– Video for Windows footage.
To display a footage item in the Footage window:
Double-click a footage item in the Project window.
To display .mov or .avi movies in the standard After Effects Footage window:
Press Alt (Windows) or Option (Mac OS) as you double-click a footage item in the Project window. After Effects Footage windows provide editing commands not available in Video for Windows or QuickTime Footage windows.

Changing magnification in windows
The lower left corner of a Composition, Layer, or Footage window shows the current magnification. When you change magnification, you change the appearance of the pixels in the window, not the actual resolution of the composition.
To zoom in or out:
Do one of the following:
Using the zoom tool, click inside the window you want to magnify.
Using the zoom tool, press Alt (Windows) or Option (Mac OS) as you click inside the
window you want to reduce.
Double-click the zoom tool in the toolbox to view at actual size.
Choose a magnification from the menu in the lower left corner of a Footage, Layer, or
Composition window.
Viewing safe zones and grids
In Footage, Layer, or Composition windows, you can display safe zones for titles and action, as well as grids used for aligning layers.
Television sets enlarge a video image and allow some portion of its outer edges to be cut off by the edge of the screen. This is known as overscan. The amount of overscan is not consistent across television sets, so you should keep important parts of a video image, such as action or titles, within margins known as safe zones. When you arrange layers in a composition, do the following:
Keep important scene elements, graphics, and actors within the action-safe zone.
Keep titles and other text within the title-safe zone.
ADOBE AFTER EFFECTS 5.0
After Effects also provides grids that you can use to help arrange and align layers. Set the grid spacing using the Grids & Guides Preferences dialog box.

Changing safe-zone margins and grid spacing
You can change the percentage of window area marked as title-safe or action-safe, and you can change the number of grid cells. Safe-zone margins represent the percentage of image area not included in the safe area. You can set spacing options for standard grids or proportional grids. The size of proportional grids increases or decreases when the compo­sition size changes; the size of standard grid squares remains the same regardless of composition size.
To change safe-zone margins:
Choose Edit > Preferences > Grids & Guides, type values for Action-Safe Margin and Title-Safe Margin, and click OK.
To change grid spacing:
Choose Edit > Preferences > Grids & Guides, type a value for Gridline Every, type a value for Subdivisions, and click OK.
To change proportional grid spacing:
Choose Edit > Preferences > Grids & Guides, type Horizontal and Vertical values for Proportional Grid, and click OK.
Using rulers and guides
You can display rulers along the sides of the Composition, Layer, and Footage windows to provide a visual guide for positioning and editing your footage. Using the cross hair in the upper left corner of the rulers, you can change the origin, or zero point, in both rulers. Changing the zero point makes it easy to measure from a specific point in the image. By default, rulers are hidden.
For added precision in positioning objects, you can create guide lines. You can also lock guide lines to prevent them from being repositioned.
Note: Rulers and guide lines are only a reference in the Composition, Layer, and Footage windows. They do not appear in your rendered movie.
To display or hide rulers:
Choose View > Show Rulers or Hide Rulers.
ADOBE AFTER EFFECTS 5.0
To set the zero point in rulers:
Drag the cross hair from the intersection of the two rulers (in the upper left corner) into the image area.
To create, reposition, lock, hide, or remove a guide line:
Do any of the following:
Position the pointer inside either ruler and drag where you want to create a guide line.
In the image area, drag a guide to reposition it.
To lock or unlock guides, choose View > Lock Guides.
In the image area, drag a guide line into a ruler to remove it.
To display or hide all guide lines, choose View > Show Guides or Hide Guides.
To remove all guide lines, choose View > Clear Guides.

Viewing color and alpha channels
You can preview the red, green, blue, and alpha channels of a still image or movie in a Footage window, Layer window, or Composition window. When you view a color channel, areas with that color are displayed according to the color value of each pixel. For example, if you view the red channel, areas with high red values are displayed as white.
To see the color values in a color channel displayed in the channel’s own color instead of white, hold down Shift and click the desired color channel icon.
When you preview the alpha channel, After Effects displays transparent and opaque areas as black and white to make identification easier. Degrees of opacity appear as shades of gray.
CHAPTER 1
58
Working with Projects, Windows, and Palettes
To view a color channel or alpha channel:
1 Open the Composition, Layer, or Footage window to view a channel for a composition,
layer, or footage item, respectively.
2 At the bottom of the window, click the icon that corresponds to the channel you want
to display.
A. Red channel B. Green channel C. Blue channel D. Alpha channel
Taking and viewing a window snapshot
When you want to compare one view to another in the Composition, Layer, or Footage window, take a snapshot of one view and temporarily replace the window image with the snapshot. For example, you might want to compare two frames in different locations in a movie. You can instantly show and hide the snapshot to identify differences between the views. If you have a sound card installed, you hear a sound when you take a snapshot.
BCD
A
When working with snapshots, here are some tips to keep in mind:
Snapshots taken in one kind of window can be displayed in another kind. For example,
you can take a snapshot of a Layer window and display the snapshot in the Composition or Footage window.
Displaying a snapshot does not replace the content of the window.
If the snapshot has a different size or aspect ratio than the window in which you display
it, the snapshot is resized to fit the window.
Choose Edit > Purge > Snapshot to free up memory used by your snapshots.
Snapshots are for reference only and do not become part of the layer, composition, or
rendered movie.
To take a snapshot:
Click the take-snapshot icon at the bottom of the window, or press Shift+F5.
ADOBE AFTER EFFECTS 5.0
To view a snapshot:
Click and hold the display-snapshot icon at the bottom of the window, or press F5.
To take and view multiple snapshots:
Do any of the following:
Hold down Shift and press F5, F6, F7, or F8 to take separate snapshots.
Press and hold F5, F6, F7, or F8 to view the corresponding snapshots.
To purge any snapshot, hold down Ctrl+Shift (Windows) or Command+Shift (Mac OS)
and press F5, F6, F7, or F8.
For more information on using shortcut keystrokes, see the Quick Reference Card.
Viewing a specific frame
The duration of a composition, a layer, or a footage file is represented visually by the time ruler. On the time ruler, the current-time marker indicates the frame you are viewing or
editing, and the frame appears in the corresponding window. You can view a different frame by typing a number or by dragging the current-time marker.
User Guide
59
In a Layer or Footage window, the time ruler appears near the bottom of the window. In a Composition window, the time ruler appears in the corresponding Timeline window. Keep in mind that the time rulers in different windows represent different durations. The time ruler in Layer and Footage windows represent the duration of the contents of that window, in contrast to the time ruler in the Timeline window, which represents the duration of the entire composition.
Current-time marker in the Timeline window (left) and in the Layer window (right)
Like the Timeline window, Layer and Footage windows include viewing-area markers that you can use to magnify or shrink the part of the time ruler displayed.
CHAPTER 1
60
Working with Projects, Windows, and Palettes
To view a specific frame by dragging:
In the time ruler, drag the current-time marker to a new point in time.
To view a specific frame numerically:
1 Choose View > Go to Time, or click the current-time display in a Footage, Layer,
Composition, or Timeline window.
2 Type a new time and click OK.
To step forward or back a specified number of frames from the Go to Time dialog box, type + or +- in front of the number, such as +5 or +-5. (If you simply type - in front of
the number, After Effects jumps to a negative time.)
Discontinuing window updates
Press the Caps Lock key to prevent After Effects from updating Footage, Layer, or Compo­sition windows. This is useful for a Layer or Composition window that takes a long time to update. When Caps Lock is active, all open Footage, Layer, or Composition windows display the last update you made before pressing Caps Lock, regardless of the changes you make. As soon as you make a change that would appear in a window, After Effects adds a red outline to any affected windows, and the windows are not updated. After Effects continues to update window controls such as motion paths, anchor points, and mask outlines as you move them. To resume window updates and display all changes made while Caps Lock was active, press Caps Lock again to deactivate it.

Working with Projects, Windows, and Palettes

Info palette

The Info palette describes the area under the mouse pointer as you drag across a footage frame in the Composition, Layer, or Footage window. This palette displays values for the pixel color (R,G,B), alpha channel (A), and coordinates of the current position. When you modify a layer property graphically, the bottom portion of this palette displays precise values that relate to the layer instead of the pointer. For example, when you drag a layer, the Info palette displays the coordinates of the layer’s center point and the offset from its last position. This makes it easy to move a layer by a specific number of pixels in either axis. During other operations, the Info palette provides context-sensitive information, such as the progress of rendering a window preview.
The X coordinate represents position in the horizontal axis, and the Y coordinate repre­sents position in the vertical axis. Values for these coordinates are in pixels. The X and Y coordinates are relative to the origin (0,0), which is fixed at the upper left corner of the image area. The upper right portion of the Info palette displays the X and Y coordinates of the pointer. As you drag a layer, the lower portion of the Info palette displays the X and Y coordinates of the layer’s anchor point. The lower portion of the Info palette also displays Z coordinates if the layer includes 3D animation.
If the zero point differs from the origin, X' and Y' coordinates appear in the Info palette below the X and Y coordinates. These values measure the distance from the zero point or the ruler.
Note: The origin of the image area is different than the origin, or zero point, of the rulers. You can set the ruler’s zero point to match the origin of the image area, but you cannot change the origin of the image area.
To change the Info palette RGBA display:
Choose an option such as Percent or Web from the Info palette menu. Selecting Auto Color Display automatically switches between 8 bits per channel and 16 bits per channel depending on the project’s color depth. Clicking anywhere on the palette cycles through the display options.

Chapter 2: Preparing and Importing Footage
footage item is the basic unit in an After Effects project. Before you begin animating, you need to import footage into After Effects. You can import moving image
A
files, still-image files, still-image sequences, audio files, layered files from Adobe Photoshop and Adobe Illustrator, and other After Effects projects and projects created in Adobe Premiere. As you build a project, you can import footage items at any time.
How After Effects works with imported files
When you import files, After Effects does not copy the footage item itself into your project but creates a reference link in the Project window to the footage item. This saves disk space.
If you delete, rename, or move an imported source file, you break the reference link to that file. When a link is broken, the name of the source file appears in italics in the Project window, and the File Path column lists it as missing. If the footage item is available, you can reestablish the link—usually just by double-clicking the item and selecting the file again. See “Replacing and substituting footage” on page 97.
65
If you use another application to modify footage that is used in a project, the changes appear in After Effects the next time you open the project. See “Opening footage in its original application” on page 95.
When you add a footage item to an After Effects composition, you create a new layer, and the footage item becomes the source for the new layer. You can replace the source without affecting any edits you make to the layer properties.

Preparing a still-image file for import into After Effects

Before you import a still image into After Effects, prepare the file as completely as possible. It is usually easier and faster to prepare a file in its original application; this also reduces rendering time in After Effects. Consider doing the following before you import still­image files into After Effects:
CHAPTER 2
66
Preparing and Importing Footage
Set the pixel dimensions to the resolution you will use in After Effects. If you plan to scale
the image over time, set image dimensions that provide enough detail at the largest size the image has in the project. The maximum resolution you can use in After Effects is 30,000 x 30,000 pixels. For D1 or DV, see “Using square-pixel footage for output to D1 or DV NTSC” on page 89.
Specify an even-numbered resolution for files imported into compositions that also use
even-numbered resolution, and odd numbers for compositions using odd-numbered resolution. See the Adobe Web site for technical papers with more information.
Crop the parts of the image that you do not want to be visible in After Effects.
Correct the contrast and color balance for broadcast video, if necessary.
Create an alpha channel if you want to designate areas as transparent.
If final output will be broadcast video, avoid using thin lines (such as 1-pixel lines) for
images or text because they may appear to flicker. If you must use thin lines, add a slight blur so the line or text displays on both video fields instead of flickering between them.
Save the file using the correct naming convention. For example, if you plan to import the
file to After Effects on a Windows system, save the file using a three-character extension. If you plan to import the file to a Mac OS, use a name of 31 characters or fewer.
Make sure that the file format is supported on the operating system you plan to use.
For information on preparing and importing interlaced motion video to After Effects, see “Preparing motion footage for import” on page 83.
Working with higher image resolutions
After Effects supports a maximum image resolution of 30,000 x 30,000 pixels for import­ing and rendering files. Resolution refers to the dimensions (width and height) of an image measured in pixels. When you work with higher resolutions, you can use a wider variety of formats, such as IMAX frames (4096 x 3002 pixels), full-aperture/silent frames (4096 x 3112 pixels), and other large-format media.
When working with high-resolution images, consider the following:
All input and output modules in After Effects support increased resolutions except PICT
(4,000 x 4,000 pixels), BMP (16,000 x 30,000 pixels), and PXR (30,000 x 16,000 pixels).
ADOBE AFTER EFFECTS 5.0
The maximum resolution you can import or export is limited by the amount of physical
RAM available to After Effects. When working with large frame sizes, minimize the RAM used by the system or other software running on your computer, but be sure to leave at least 4 MB unused to handle system software requirements for additional RAM.
The following formula helps you determine the amount of RAM you need based on the
footage: Image Width in Pixels x Image Height in Pixels x 4 Bytes of Memory for 32 bits­per-pixel (bpp) or 8 Bytes of Memory for 64 bpp. For example, a 30,000-x-30,000-pixel image requires 3.5 GB of RAM to import and display each frame. However, a 30,000-x­486-pixel image requires only 60 MB of RAM. Memory requirements for 16 bits-per­channel (bpc) project color depth are approximately double those for 8 bpc.
Changing the default duration of still images
When you add a still image to a composition, its default duration is the duration of the composition. You can manually trim the duration of a still image and change the default duration of still footage in the Import Preferences dialog box. See “Understanding trimming” on page 139.
To change the default duration of still footage:
1 Choose Edit > Preferences > Import.
2 Under Still Footage, do one of the following, and then click OK:
User Guide
67
Select Length of Composition: sets the same duration for the still image as the compo-
sition into which it is placed.
Type numbers in the text box for the duration you want to use.
Specifying interpretation rules
The Interpretation Rules.txt file describes how After Effects interprets field order, alpha channel, frame rate, and pixel aspect ratio when importing footage. You can customize this file in any text editor and add or delete entries, to save time. When you import, After Effects reads the file and follows any applicable rules, as long as Interpretation Rules.txt is stored in the same folder as the After Effects application. You can always override these interpretations after importing. For more information about specifying interpretation rules, see online Help.
CHAPTER 2

Preparing and Importing Footage
Importing files into a project
With After Effects 5.0, you use the same Import File dialog box to import any usable file into After Effects. To save time and minimize the size and complexity of a project, import a footage item once and then use it multiple times in a composition. It is occasionally useful, however, to import a footage item more than once, such as when you want to use it at two different frame rates.
After Effects supports 24- and 32-bit files using 8 bits per channel (bpc)—including alpha channel—and the RGB, Grayscale, and Black-and-White color modes. For a list of supported file formats, see online Help.
Note: The After Effects Production Bundle provides support for 16 bpc.
To import footage into a Project window:
1 Open a project or choose File > New > New Project.
2 With the Project window active, choose File > Import > File.
3 In the Files of Type pop-up menu, choose the setting you want to use:
All Acceptable Files (the default selection). Shows files that After Effects recognizes as
supported formats.
All Footage. Shows only supported footage files. Project files are not shown.
All Files (*.*). Shows all files, whether or not After Effects recognizes them as supported
formats. (This is useful for compatible files transferred from another platform, such as a Silicon Graphics workstation.) This option requires you to identify the format.
A specific format. Restricts the files shown to the format you choose from the menu. (Use
this option as a convenience when the files you want are in large folders containing files of mixed types.)
4 Do one of the following:
To import a file, locate and select it, and then click Open.
To import multiple files from the same location, hold down Ctrl (Windows) or Shift
(Mac OS), select the items you want, and then click Open.
To import all the files in a folder, locate and select the folder, and then click the Import
Folder button.
ADOBE AFTER EFFECTS 5.0
The imported footage appears in the Project window. For more information about importing folder contents, see “Importing a sequence of still-image files” on page 70.
Note: If the Interpret Footage dialog box appears instead, the imported footage item contains an unlabeled alpha channel, and you’ll need to select a type or click Guess to let After Effects determine the type. See “Interpreting alpha channels as straight or premultiplied” on page 72.
To search for a file in Mac OS, click Find, type the name of a file or folder, and click OK. After Effects finds the first file or folder that matches the text.
To import items by dragging:
From the desktop or a folder, select one or more items you want to import and drag them to the After Effects application icon (on the Windows Explorer or Macintosh Finder) or to the Project window (in After Effects).
If you import a folder by dragging it from the desktop, the contents of that folder are imported as a sequence. To import the contents as individual footage files, press Alt (Windows) or Option (Mac OS) as you drag. (This is the equivalent of clicking the Import Folder button in step 4 of the previous procedure, “To import footage into a Project window.”) If you always want the layered footage that you drag into After Effects to be imported as a composition, you can specify this in your Import Preferences.

Preparing and Importing Footage

Importing a sequence of still-image files

After Effects can import a sequence of still images with the same numeric or alphabetic filename pattern and automatically combine them into a single sequence file. In sequence files, each original file represents one frame. After Effects uses the dimensions and bit depth of the first image in the sequence. It then imports (in numeric or alphabetic order) all still images in the folder that have the same filename pattern and file type as the one you selected.
A sequence of still-image files (left) becomes one image sequence when imported into After Effects (right).
To import a sequence of still images:
1 Move all the files in the sequence to the same folder.
2 In After Effects, choose File > Import > File.
3 Locate and select any file in the sequence.
4 Select the file format name Sequence option.
5 If you want to import alphabetically, select Force Alphabetical Order. Then click Open.
Note: You can import a subset of a numbered sequence by using a variation of this procedure. In step 3, select the first file you want to include, hold down Shift, and select the last file you want to include. In this case, only the two files you selected appear highlighted in the Import File dialog box, but all files that fall between those two in the sequence will also be imported.
ADOBE AFTER EFFECTS 5.0
To import a folder of still images as a sequence by dragging:
1 Drag the folder from the desktop to the After Effects Project window.
After Effects imports the first sequence that is listed in the folder, based on the filename.
You can also import an existing sequence as individual footage files. There are two ways to accomplish this.
To import a sequence as individual footage files:
Do either of the following:
Choose File > Import > File to open the Import File dialog box, locate and select the
folder, and then click the Import Folder button.
On the desktop, hold down Alt (Windows) or Option (Mac OS) and drag the folder into
either the After Effects icon on the desktop or into the Project window.
When you import a sequence of still images, they assume the frame rate specified in the Preferences. The default rate is 30 frames per second (fps). You can change the frame rate for the sequence either before or after importing.
To change the default frame rate for a sequence before importing:
1 Choose Edit > Preferences > Import.
2 Under Sequence Footage, type a new default frame rate, and then click OK.
User Guide
71
To assign a frame rate to a sequence you’ve already imported:

2 Choose File > Interpret Footage > Main.
3 Select Assume This Frame Rate and type the frame rate you want.
CHAPTER 2
72
Preparing and Importing Footage

Importing footage containing an alpha channel

The color information in a typical footage item is contained in three channels: red, green, and blue. In addition, a footage item can include a fourth channel, called an alpha channel, that contains transparency information for the parts of the image that are partially or completely transparent. An alpha channel is often used as a matte for creating effects. When used in After Effects, a matte defines the transparent areas for its own or another layer. White areas define what is opaque, and black areas define what is transparent. See “Using a footage item with an alpha channel” on page 238.
Many file formats can include an alpha channel, including Adobe Photoshop, ElectricImage IMAGE, TGA, TIFF, EPS, PDF, QuickTime (saved at a bit depth of Millions of Colors+), and Adobe Illustrator. For Adobe Illustrator EPS and PDF files, After Effects automatically converts empty areas to an alpha channel.
Interpreting alpha channels as straight or premultiplied
When you import a footage file containing an alpha channel, After Effects determines if it is straight or premultiplied. If the alpha channel is unlabeled, After Effects displays the Interpret Footage dialog box and prompts you to select Ignore Alpha, Straight (Unmatted), Premultiplied (Matted with Black), Premultiplied (Matted with White), or Guess. When you select Guess, After Effects determines the interpretation method. For information on straight and premultiplied alpha channels, see online Help.
Correctly identifying the type of alpha channel when you import a file can prevent prob­lems, such as undesirable colors at the edge of an image or a loss of image quality at the edges of the alpha channel. If a color inaccuracy, such as a halo, appears along the edges of an alpha channel in a composition, try changing the interpretation method.
If a footage item doesn’t have an alpha channel or transparency information, you can create an alpha channel in After Effects using a layer mask. See “Working with masks” on page 238.
Choosing an interpretation method for alpha channels
You can change the interpretation method for a file after you import the file. You can also change the default alpha channel interpretation in the Import Preferences dialog box, in the Interpret Unlabeled Alpha As pop-up menu. This is especially useful for importing footage from an application that consistently uses one type of unlabeled alpha channel.
ADOBE AFTER EFFECTS 5.0
The interpretation methods include:
Ask User Displays a dialog box containing interpretation options each time you import an
unlabeled alpha channel.
Guess Attempts to determine the type of alpha channel used in the image. If After Effects
cannot guess confidently, it beeps.
Ignore Disregards all transparency data in the file.
Straight (Unmatted) Interprets the alpha channel as straight alpha. If the application you
used to create the footage does not premultiply the alpha channel, select this option.
Premultiplied (Matted with Black) Interprets the alpha channel as premultiplied with black.
Premultiplied (Matted with White) Interprets the alpha channel as premultiplied with white.
To import a footage file containing an alpha channel:
1 Choose File > Import > File. Locate and select the file and click Open.
2 In the Interpret Footage dialog box, select an option for alpha channel type. If you select
Treat As Premultiplied (Matted with Color), you can click the eyedropper and select a color.
3 Click OK.
User Guide

2 For Interpret Unlabeled Alpha As, select the interpretation methods you want used by
default, and click OK.
CHAPTER 2
74
Preparing and Importing Footage
Importing Adobe Photoshop files
You can import an Adobe Photoshop file directly into an After Effects project with the option of preserving individual layers, layer masks, and so forth from Adobe Photoshop. Importing layers makes it easy to prepare still images for animation using the image­editing tools in Adobe Photoshop.
Preparing layered Adobe Photoshop files
Importing layers into After Effects makes it possible to prearrange a composition in Adobe Photoshop using layers, and preserve those layers in After Effects so that they are ready for animation. Preserving layers is also useful if you want to use a single Adobe Photoshop file as a source for both print and dynamic media.
Before you import a layered Adobe Photoshop file, prepare it thoroughly to reduce preview and rendering time. Avoid problems importing and updating Adobe Photoshop layers by naming them properly. Before you import them into After Effects, do the following:
Organize and name layers. If you change a layer name or delete a layer in an Adobe
Photoshop file after you have imported it into After Effects, After Effects is unable to find the original layer name, and the Project window lists that layer as Missing.
Make sure that each layer has a unique name, because After Effects manages layers by
their names. Duplicate layer names can cause problems when you update footage.
If you want to import a composited version of a layered Photoshop file along with a
layered version, select the Include Composited Image With Layered Files option in the Photoshop Saving Files Preferences dialog box.
Importing layered Photoshop files
After Effects imports attributes that were applied in Adobe Photoshop, including position, transfer modes, opacity, visibility, transparency (alpha channel), layer masks, adjustment layers, common layer effects, layer clipping-paths, vector masks, and clipping groups.
You can import a multilayered Adobe Photoshop file in the following ways:
As a new composition, with each layer in the Adobe Photoshop file becoming a separate
layer in the composition
As a single still footage item imported from any one layer in the Adobe Photoshop file
ADOBE AFTER EFFECTS 5.0
As a single still footage item imported from all the Adobe Photoshop layers merged
together
When you import a layered Adobe Photoshop file as a composition, all the layers contained in the composition retain their original positions as set in Adobe Photoshop. You can open the composition in After Effects and animate the layers.
To import a layered Adobe Photoshop file as a new composition:
1 Choose File > Import > File.
2 In the Import File dialog box, make sure that All Acceptable Files is selected for Files of
Type, and then locate and select the Adobe Photoshop file you want to import.
3 Choose Composition in the Import As pop-up menu, and then click Open.
The original filename is used twice in the Project window: for the file as a composition and for the folder containing each Adobe Photoshop layer as a separate footage items.

Note: When you import one Adobe Photoshop layer as a single footage item, its name in the Project window consists of the layer name followed by the Adobe Photoshop filename.
Using transparent areas and layer masks from Adobe Photoshop
Adobe Photoshop supports a transparent area and one optional layer mask (alpha channel) for each layer in a file. You can use these layer masks to specify how different areas within a layer are hidden or revealed. When you import one layer of an Adobe Photoshop file, After Effects combines the layer mask (if present) with the transparent area and imports it as a straight alpha channel.
CHAPTER 2
76
Preparing and Importing Footage
If you import a layered Adobe Photoshop file as a merged file, After Effects merges the transparent areas and layer masks of all the layers into one alpha channel that is premulti­plied with white. See “Importing layered Photoshop files” on page 74.
If a layered Adobe Photoshop file contains clipping groups, After Effects imports each clipping group as a composition nested within the main composition. After Effects automatically applies its Preserve Underlying Transparency option to each layer in the clipping-group composition, to maintain transparency settings.
When you import a Adobe Photoshop file as a composition, any clipping paths in the imported layers are converted to After Effects masks. You can then modify and animate these masks within After Effects.
After Effects also supports any blending modes applied to the file. For more information on the Preserve Underlying Transparency option, see “Preserving underlying trans­parency during compositing” on page 261.
Using adjustment layers from Adobe Photoshop
Adjustment layers in Adobe Photoshop versions 4.0 and later change the color and tonal qualities of an image without permanently modifying the original image. Adobe Photo­shop adjustment layers affect the appearance of all layers below them. When you import an Adobe Photoshop file containing one or more adjustment layers, After Effects directly converts the Adobe Photoshop adjustment layers to After Effects adjustment layers. Turn off the Adjustment Layer switch in After Effects to remove the effect and display the layer as a white solid. To remove the effect and the white solid, either delete the adjustment layer or turn off the Video switch for the layer. See “Creating an adjustment layer” on page 128 and “About After Effects Audio/Video switches” on page 146.
Using Adobe Photoshop layer effects (styles)
In Adobe Photoshop 5.0 and later, you can use a layer effect (or style) to modify the layer to which it is applied. When you import an Adobe Photoshop file as a composition, and one or more of the layers contain layer effects, then After Effects includes the effects and the layer as two or more separate layers in the Timeline window.
Note: Only some Adobe Photoshop styles (effects) can be imported into After Effects. These include Drop Shadow, Inner Shadow, Outer Glow, Inner Glow, Bevel and Emboss, and Color Fill.
ADOBE AFTER EFFECTS 5.0
You can edit or remove a layer effect by using either the Timeline window or the Effect Controls window. You can also animate these Adobe Photoshop layer effects over time.
To edit an Adobe Photoshop layer effect in After Effects:
1 Open the composition containing the layer effect.
2 In the Timeline window, select the layer containing the effect and press E to display the
effect properties.
3 Click the underlined value you want to change and type a new value.
A single Adobe Photoshop layer effect can become up to five layers and effects in After Effects. You may need to edit multiple copies to achieve the desired result.
Importing an Adobe Illustrator, PDF, or EPS file
You can import Adobe Illustrator, many PDF, and EPS files directly into After Effects. When you import an Adobe Illustrator file, After Effects converts all text information to paths, eliminating the need to create outlines in Adobe Illustrator before importing. If you import a file without creating outlines, make sure that all fonts used in the file are available to After Effects when you import.
User Guide
77
When you import an Adobe Illustrator file, After Effects automatically makes all empty areas transparent by converting them into an alpha channel.
After Effects can import Adobe Illustrator CMYK files. However, to maintain accurate
color, convert your CMYK images to RGB images in Adobe Illustrator. When you import Adobe Illustrator CMYK images, After Effects remaps the CMYK colors to RGB, and may subtly shift colors.

Continuously rasterizing an Adobe Illustrator file
You can continuously rasterize an Illustrator file at any time while designing your project. Whether you choose to continuously rasterize or not, if you view and render a composition using Best Quality, After Effects anti-aliases (smooths) the art. For general information about rasterizing, see your Adobe Illustrator documentation or visit the Adobe Web site and search for rasterize.

4 In the Import Adobe Illustrator dialog box, select a layer to import from the file, or
choose Merged Layers to import all layers in the file as a single layer in After Effects. Then click OK.
Importing Adobe Illustrator paths as masks
You can use an Adobe Illustrator path as a mask in an After Effects layer composition by copying the path in Adobe Illustrator and pasting it directly into the Layer or Composition window in After Effects. After Effects creates a mask for each closed path copied from Adobe Illustrator. For more information on using masks, see “Working with masks” on page 238.

To import an Adobe Illustrator path as a mask:
1 In Adobe Illustrator, create your path, select all of the points along the path, and then
choose Edit > Copy.
2 In After Effects, open the Layer window for the layer into which you want to import
the path.
3 Choose Edit > Paste.
Note: This process works best if your Adobe Illustrator Preferences are set with AICB Clipboard and Preserve Paths selected.

Importing an After Effects project

You can import one After Effects project into another. Everything from the imported project, including footage files, compositions, and folders, appears inside a new folder in the current Project window. When you want to repeat a complicated mask, effect, or anima­tion in a different project, you can import the project containing the effect and simply replace the source footage, keeping all the effect, composition, and layer settings intact.
See “Importing files into a project” on page 68 for the procedure for importing.
Importing After Effects projects from different platforms
You can open and import an After Effects project from a different operating system as long as you maintain the filenames, folder names, and either full paths or relative paths (folder locations) for all files in the project. To maintain relative paths, the source footage must reside on the same volume as the project file.
If a file format is not supported on the operating system you are using, if the file is missing, or if the reference link is broken, After Effects substitutes a placeholder item containing color bars. You can reconnect the placeholder to the appropriate file. You can use the same process to connect a footage item in the Project window to a different source file.
To relink a reference:
1 Select the placeholder or footage file in the Project window, and choose File > Replace
Footage > File.
2 In the Replace Footage File dialog box, locate and select the footage file you want to use.
Note: You can also open this dialog box by double-clicking the footage item.
ADOBE AFTER EFFECTS 5.0
For more information on substituting footage, see “Replacing and substituting footage” on page 97.
For information about creating projects for both Windows and Mac OS, see “Consider­ations for cross-platform projects” on page 40.

Importing Adobe Premiere projects

The ability to import Adobe Premiere projects eliminates the need to render the project before applying visual effects and animations in After Effects. When you import an Adobe Premiere 5.0 or later project, After Effects imports it into the Project window as both a new composition containing each Adobe Premiere clip as a layer, and as a folder containing each clip as an individual footage item. If your Adobe Premiere project contains bins, After Effects converts them to folders within the Adobe Premiere project folder.
After Effects preserves the order of clips in the Timeline, the footage duration (including all trimmed In and Out points), and the marker and transition locations. The arrangement of layers in the Timeline window is based on the arrangement of clips in the Premiere Time­line. After Effects adds Adobe Premiere clips to the Timeline window as layers in the order they appeared—from the bottom up and from left to right—in the Premiere Timeline.
User Guide
81
Transitions and titles included in your Adobe Premiere project appear in the After Effects composition as solid layers, maintaining their original location and duration. After Effects discards all transparency and motion settings. See “Importing files into a project” on page 68 for the procedure for importing.
Import Adobe Premiere projects in the same way you import footage files: choosing File > Import > File, and locating the Adobe Premiere project file that you want to import.
Importing 3D-image files
After Effects can import 3D-image files saved in Softimage PIC, RLA, and Electric Image EI format. These 3D-image files contain red, green, blue, and alpha (RGBA) channels, as well as auxiliary channels with optional information, such as z depth, object IDs, texture coordinates, and more. The Standard Version of After Effects reads and displays the RGBA information.
CHAPTER 2
82
Preparing and Importing Footage
With RLA files, all of the auxiliary channels are included in a single file. Softimage PIC files have a corresponding ZPIC file that contains the z-depth channel information. Although you can’t import a ZPIC file, you can access the additional channel information as long as the ZPIC file is stored in the same folder as the imported PIC file.
Similarly, Electric Image (EI) files can now have associated EIZ files with z-depth channel data. Just as with ZPIC files, you cannot import EIZ files into After Effects; instead, you store them in the same folder as the EI files. For information about creating EIZ files, see your Electric Image documentation.
Importing an audio file
You can import a variety of audio file formats directly into After Effects. When you add audio-only files to a composition, they appear as layers in the Timeline window. You can adjust the audio preview settings, such as sample rate, in the General Preferences dialog box. These settings change the quality of audio playback when you preview the compo­sition, not when you render it. For more information, see “Using audio layers” on page 153.
Importing Cineon files
You can import Cineon 4.5 or Digital Picture Exchange (DPX) files directly into an After Effects project as individual frames or as a sequence of numbered stills. Once you have imported a Cineon file, you can use it in a composition and then render the composition as a Cineon sequence. See “Importing a sequence of still-image files” on page 70.
Cineon files are commonly used to transfer motion-picture film to a digital format. To preserve the full dynamic range of motion-picture film, Cineon files are stored using loga­rithmic 10 bits per channel (bpc). However, After Effects internally uses linear 8-bpc color, (or 16-bpc, for the Production Bundle only). By default, After Effects stretches the atten­dant logarithmic values to the full range of values available. You can then use the Cineon Import Options dialog box or the Cineon Converter effect to control the conversion. (If you are working with a film sequence in which exposure conditions vary over time, you can vary the conversion over time by setting keyframes.) For information on using the Cineon converter, see online Help.
ADOBE AFTER EFFECTS 5.0
To import a Cineon sequence:
1 Choose File > Import > File.
2 For the file type, select Cineon, and then select Cineon Sequence.
3 Locate and select the first numbered Cineon sequence file.
4 Select the Cineon Sequence option, and then click Open.
The Cineon file or sequence appears in the Project window.
To convert a Cineon sequence from logarithmic to linear:
1 Select the sequence in the Project window, and choose File > Interpret Footage > Main.
2 In the Interpret Footage dialog box, click More Options.
3 In the Cineon Conversion dialog box, select the Logarithmic Conversion option, click
OK, and click OK again.
When you are ready to produce output from the Cineon file, it is important that you reverse the conversion from logarithmic to linear.

Preparing motion footage for import

Some of the source footage you use may have been created digitally (for example, in Adobe Photoshop or Adobe Premiere), but other footage may need to be transferred to the computer from analog sources, such as film and videotape. When you work with After Effects, understanding some of the differences among media can help you decide how to handle footage as you transfer it between digital and analog devices. For information on the different types of video, see online Help.
Preparing a movie for import when final output is NTSC interlaced video
You can edit and prepare video footage in other applications, such as Adobe Premiere, before importing it into After Effects. If you want to render the footage from After Effects as NTSC interlaced video, do not field-render or create interlaced frames when you render the movie from the other application. It’s acceptable to render interlaced video for tempo­rary files, but 60 progressive gives better quality. Make sure that you keep track of the orig­inal field order so you can correctly render it in After Effects. See “Field rendering” on page 87 and “Testing the field-rendering order” on page 387.
CHAPTER 2
84
Preparing and Importing Footage
As long as the footage is on a computer, it should remain noninterlaced. Keeping the footage in noninterlaced format preserves more image quality and saves you the extra step of separating fields in After Effects. Once it’s ready to go to your nonlinear editor, such as Adobe Premiere, it should be interlaced.
When you render the movie from the other application, render it at 60 fps of frame­rendered (noninterlaced) video. After you integrate it into a composition, After Effects can render it to high-quality field-rendered (interlaced) frames at 30 fps for videotape.
Preparing motion-footage frame rates for final output
When you import motion footage into After Effects, the file’s frame rate does not change. If you plan to output your footage to a different frame rate, you can make it conform to the new frame rate in After Effects. Conforming ensures that frames disperse evenly over the new output frame rate.
Conforming footage does not alter the original footage, only the reference that is used by After Effects. When it conforms, After Effects changes the internal duration of frames but does not change the frame content. If the conformation is a large amount, the footage plays back at a different speed. For example, if you change the frame rate from 15 fps to 30 fps, the footage plays back faster.
It’s best to make the frame rate the same as the final output frame rate for your project. This way, After Effects renders each frame, and the final output does not omit or duplicate frames. However, in order not to drastically change the speed of your motion footage, it may be beneficial to conform only by a small amount, making the new frame rate divisible by the output rate. For example, if your original footage has a frame rate of 29.97 fps and you want to output it for playback on CD-ROM at 10 fps, you can conform to 30 fps. At 30 fps, the frames are divisible by 10, so After Effects can evenly render every third frame.
Note: If you want to output original NTSC footage as PAL or vice versa, you must have access to hardware that supports each format.
To change the frame rate of a motion footage file:
1 Select the footage file in the Project window.
2 Choose File > Interpret Footage > Main.
ADOBE AFTER EFFECTS 5.0
3 Select Conform to Frame Rate, and type a new frame rate in the Frames Per Second box.
Then click OK.
Note: This procedure can change the synchronization of audio and video files. Be sure to check your files and make any necessary adjustments.

Using interlaced video in After Effects

If you want to use interlaced or field-rendered footage (such as from NTSC video) in an After Effects project, you will get the best results if you separate the video fields when you import the footage. After Effects separates video fields by creating a full frame from each field, preserving all of the image data from the original footage.
When importing interlaced video that was originally transferred from film, you can remove the 3:2 pulldown that was applied during the transfer from film to video as you separate fields so that effects you apply in After Effects don’t appear distorted. See “Removing 3:2 pulldown from video transferred from film” on page 87.
Separating fields
Separating fields is critical if you plan to make significant changes to the footage. When you scale, rotate, or apply effects to interlaced video, unwanted artifacts, such as crossed fields, are often introduced. By separating fields, After Effects accurately converts the two interlaced frames in the video to noninterlaced frames, while preserving the maximum amount of image quality. Using noninterlaced frames allows After Effects to apply edits and effects consistently and at the highest quality.
User Guide
85
After Effects creates field-separated footage from a single formerly interlaced field by splitting fields into two independent frames. Each new frame has only half the infor­mation of the original frame, so some frames may appear to have a lower resolution than others when viewed at Draft quality. When you render the final composition, After Effects reproduces high-quality interlaced frames for videotape. When you render a movie at Best quality, After Effects interpolates between the scan lines of a field to produce maximum image quality.
Note: After Effects automatically separates fields for D1 and DV video footage files. You can manually separate fields for all other types of video footage in the Interpret Footage dialog box. For more information, see “Specifying interpretation rules” on page 67.
CHAPTER 2
86
Preparing and Importing Footage
To separate video fields in imported footage:
1 Select the footage item in the Project window.
2 Choose File > Interpret Footage > Main.
3 Select an option from the Separate Fields pop-up menu.
4 Click Motion Detect to increase image quality in nonmoving areas when the image is
rendered at Best quality. Then click OK.
Interpreting field order
Interlaced video has a field order defining the order in which the two video fields (upper and lower) are displayed. A system that draws the upper lines before the lower lines is called upper-field first; one that draws the lower lines before the upper lines is called lower- field first. The order in which the fields are displayed is important, especially when the fields contain motion. If you separate video fields using the wrong field order, motion will not appear smooth.
Some programs, including After Effects and current versions of Media 100, label the field order when rendering interlaced video files. When you import a labeled video file, After Effects honors the field order label automatically. You can override the field order using the Interpretation Rules file. For more information about field order, see “Specifying interpretation rules” on page 67.
If a file does not contain a field order label, you can match the original field order of your footage. If you are not sure which field order was used to interlace a footage item, use the procedure below to find out.
To determine the original field order:
1 Select the item in the Project window.
2 Choose File > Interpret Footage > Main.
3 In the Interpret Footage dialog box, select Upper Field First from the Separate Fields
pop-up menu, and then click OK.
4 In the Project window, press Alt (Windows) or Option (Mac OS) as you double-click
the footage to open it in a Footage window.
5 If the Time Controls palette is not visible, choose Window > Show Time Controls.
6 In the Footage window, find a segment that contains one or more moving areas.
ADOBE AFTER EFFECTS 5.0
7 Using the Frame Advance button ( ) on the Time Controls palette, step forward at least
five frames in the Footage window. Moving areas should move consistently in one direc­tion. If the moving areas move backward every other frame, the wrong field-separation option has been applied to the footage.
Note: Analog capture cards can vary. DV or footage captures from IEEE 1394 FireWire/i.Link are always lower field first.
Field rendering
When you render a composition containing separated footage, set the Field Rendering option to the same field order as your video equipment. If you don’t field-render the composition, or if you field-render with the incorrect settings, the final movie may appear too soft, jerky, or distorted. See “Testing the field-rendering order” on page 387.
Removing 3:2 pulldown from video transferred from film
When you transfer 24-fps film to 29.97-fps (NTSC) video, you use a process called 3:2 pulldown, in which the film frames are distributed across video fields in a repeating 3:2
pattern. It’s important to remove 3:2 pulldown from video footage that was originally film, so that effects you add in After Effects synchronize perfectly with the original frame rate of film. Removing 3:2 pulldown reduces the frame rate by 4/5: from 30 to 24 fps or from 29.97 to 23.976 fps, which also reduces the number of frames you have to change. To remove 3:2 pulldown, you must also indicate the phase of the 3:2 pulldown. For more information on 3:2 pulldown, see online Help.
User Guide
87
Before you remove 3:2 pulldown, separate the fields as either upper-field first or lower­field first. Once the fields are separated, After Effects can analyze the footage and deter­mine the correct 3:2 pulldown phase and field order. If you already know the phase and field order, choose them.
Note: If your footage file contains frames from different sources, the phase may not be consis­tent. If this is the case, import the footage once for each phase. Then, add the footage to your composition as many times as there are phases and trim each layer to use only the appropriate frames for each phase.
To remove 3:2 pulldown from video transferred from film:
1 In the Project window, select the footage from which you want to remove 3:2 pulldown.

Setting pixel aspect ratio

It is important to set the pixel aspect ratio for a footage file at its original ratio, not the ratio of the final output. For general information about pixel aspect ratio, see online Help.
Set pixel aspect ratios for footage and compositions with these approximate values:
Square Pixels Uses a 1.0 pixel aspect ratio. Use this setting if your footage has a 640 x 480
or 648 x 486 frame size.
D1/DV NTSC Uses a 0.9 pixel aspect ratio. Use this setting if your footage has a 720 x 480
or 720 x 486 frame size, and your desired result is a 4:3 frame aspect ratio.
D1/DV NTSC Widescreen Uses a 1.2 pixel aspect ratio. Use this setting if your footage has
a 720 x 480 or 720 x 486 frame size, and your desired result is a 16:9 frame aspect ratio.
D1/DV PAL Uses a 1.0666 pixel aspect ratio. Use this setting if your footage has a 720 x 576
frame size, and your desired result is a 4:3 frame aspect ratio.
D1/DV PAL Widescreen Uses a 1.422 pixel aspect ratio. Use this setting if your footage has
a 720 x 576 frame size, and your desired result is a 16:9 frame aspect ratio.
Anamorphic 2:1 Uses a 2.0 pixel aspect ratio. Use this setting if your footage was shot
using an anamorphic film lens.
D4/D16 Standard Uses a 0.948 pixel aspect ratio. Use this setting if your footage has a
1440 x 1024 or 2880 x 2048 frame size, and your desired result is a 4:3 frame aspect ratio.
D4/D16 Anamorphic Uses a 1.896 pixel aspect ratio. Use this setting if your footage has a
1440 x 1024 or 2880 x 2048 frame size, and your desired result is an 8:3 frame aspect ratio.
