1Effects Concepts and Settings
This chapter describes concepts you should understand before you begin creating effects and
common settings adjustments that affect how you work with effects:
•Types of Effects
•Real-Time Effects and Non-Real-Time Effects
•Color Coding on Effect Icons
•Understanding the Effect Palette
•Displaying and Adjusting the Effect Palette
•Working with Effects in HD and in Progressive Frame Projects
•Changing Timeline View Settings for Effects
•Adjusting Trim Settings for Effects
•Setting Effect Grid Options
•Setting Effect Aperture Options
Types of Effects
You can divide the effects in Avid editing applications into a number of groupings, which are
described in the remainder of this topic.
There is considerable overlap within these groupings. For example, Timewarp effects are one of
the main types of motion effects in Avid editing applications, but they are also examples of segment effects. The following descriptions give you a basic understanding of the range of effects
available, and an introduction to some of the terminology Avid uses in its effects documentation.
Transition Effects
You apply transition effects at the cut point between two video clips that are on the same track
(the same video layer) in a sequence. Examples of transition effects are dissolves, fades, and
wipes.
Types of Effects
Segment Effects
You apply segment effects to an entire clip or group of clips in a sequence. For example, you
might apply a Color Effect to several segments in a sequence to tint those segments, suggesting
that the action they contain is taking place in the past.
Segment effects fall into two subgroups:
•Single-layer
You apply a single-layer segment effect to a segment on one video track. A single-layer
segment effect only needs one stream of video to create its effect. For example, the Mask
effect lets you mask out some parts of the video in a segment, replacing it with a solid color.
•Multilayer
You apply a multilayer segment effect to the top layer or a middle layer of segments that
contain two or more video tracks that will play simultaneously. A multilayer segment effect
requires more than one video stream to create its effect. For example, a Picture-in-Picture
effect displays video from an upper video track inside video from a lower track.
Motion Effects
Motion effects manipulate the motion characteristics in a clip, for example, by freezing action or
by varying the speed at which a clip plays. You create motion effects either by generating new
clips with fixed motion characteristics, or by using the Timewarp effects to change the motion
characteristics of clips already in a sequence. For information on motion effects, see “Creating
and Customizing Motion Effects” on page 199.
Title Effects
Title effects contain text and graphic objects that you create with one of the title tools in your
Avid editing application. You save title effects into bins as a special clip type, and edit them onto
their own layers in a sequence, usually above all other video layers. For information on title
effects, see “Creating Titles” on page 381.
2D Effects and 3D Effects
Effects in Avid editing applications are either 2D or 3D. 2D effects appear to be acting in the two
dimensions of the screen the viewer is watching and do not give an impression of depth. 3D
effects give an impression of depth, for example, by wrapping a video image around a sphere.
Some Avid effects are 2D only or 3D only, while others have both 2D and 3D versions, or can be
promoted from 2D to 3D. For specific information on working with 3D effects, see “Working
with 3D Effects” on page 361.
21
Types of Effects
Nested Effects
You apply nested effects inside other effects on the same video layer. Effect nesting allows you
great flexibility to apply multiple effects to the same segment in a sequence. For example, you
might want to apply a color effect within an existing Picture-in-Picture effect. To do this, you can
nest the color effect inside the Picture-in-Picture. For more information, see “Layered and
Nested Effects” on page 253.
Key Effects
Key effects use specific rules to define how parts of one image show through another image. The
best-known example of a key effect is a chroma key, for example, where an actor shot in front of
a blue or green screen appears to be standing in front of another background. The key effect
replaces the blue or green color in the foreground shot with parts of the background shot. For
more information, see “Layered and Nested Effects” on page 253.
Camera Effects
Camera effects control aspect ratio, format, or the apparent motion of the camera. For example,
Avid editing applications can reformat video media to different aspect ratios, allowing you to
select the area of video that is preserved in the new aspect ratio. For more information, see
“Working with Camera Effects” on page 283.
Motion Tracking and Stabilization Effects
Motion tracking lets you track the motion of an area in an image and then use the tracking data to
control the motion of another effect. You can also use tracking to stabilize an image to
compensate for camera motion. For more information, see “Motion Tracking and Stabilization”
on page 309.
Intraframe Effects
Intraframe effects let you perform paint or animated matte effect operations within one or more
individual frames in a clip. For example, you can identify part of an image with drawing tools
and apply a blur to only that part of the image. You can also use this technique to repair scratches
and other flaws on individual frames. For more information, see “Intraframe Editing” on
page 471.
PlasmaWipe Effects
PlasmaWipe effects use gradient image bitmaps to create highly-customizable wipes and
segment effects. You can use one of the many preset effects or create your own using new
gradient images. For more information, see “PlasmaWipe Effects” on page 541.
22
Real-Time Effects and Non-Real-Time Effects
AVX Plug-In Effects
Avid editing applications support the Avid Visual Extensions (AVX™) standard. AVX is a
cross-platform technology that allows software effect modules (plug-ins) to be dynamically
linked to an Avid editing application. Some effects that Avid supplies with your Avid editing
application use the AVX technology, while others do not. In general, you work in exactly the
same way with both types.
Third-party developers use AVX to create effect plug-ins that you can purchase, install, and use
to extend the effects functionality of your Avid editing application. Third-party AVX plug-in
effects might have controls that look very similar to standard Avid effect controls, or they might
have custom user interfaces.
For more information on working with third-party plug-ins, see “Working with Plug-In Effects”
on page 187.
Real-Time Effects and Non-Real-Time Effects
Effects in Avid editing applications can be either real-time or non-real-time. A real-time effect is
one that you can apply to a sequence and play without having to render it first. Rendering is a
processing operation that your Avid editing application performs to merge effect layers, creating
one stream of digital video for playback in real time. (Rendering takes time and creates a new
media file that occupies drive space.) You must render non-real-time effects before you can play
them back. You can preview non-real-time effects, or play them as an outline, without rendering
them.
A real-time effect has a small green dot in the Effect Palette and within the effect icon in the
Timeline. Effects that you must render have a small blue dot within the effect icon in the
Timeline. For more information, see “Color Coding on Effect Icons” on page 24.
You can create a sequence that has any number of real-time and non-real-time effects. However,
there are limits on how many real-time effects your Avid editing application can play at once
without rendering or otherwise reducing the amount of processing necessary during playback.
For more information, see “Real-Time Playback of Video Effects” on page 153.
When you want to play a sequence that includes effects at full quality, you might have to render
some of the effects. You will have to render any effect that is non-real-time, and you might need
to render some of the effects that are normally real-time.
23
Color Coding on Effect Icons
The exact number of effects that you must render for output depends on the following factors:
•Whether or not you have Avid input/output hardware attached to your system. If you do not
have Avid input/output hardware attached, you must render all effects before you perform a
digital cut.
•How complex your sequence is, and especially how your effects are layered on multiple
video tracks. If you have Avid input/output hardware attached to your system, real-time
effects might cause dropped frames during a digital cut. You can have your Avid editing
application select and render real-time effects that might cause dropped frames. For more
information, see “Recording a Digital Cut to Tape (Remote Mode)” and “Recording a
Digital Cut to Tape (Local Mode)” in the Help.
If you attempt to play or output a sequence that your Avid editing application cannot play in
real-time, you can display information in the Timeline that shows where the demands of the
sequence are preventing successful real-time play. For more information, see “Understanding
Real-Time Playback Information in the Timeline” on page 155. You have several options for
how to proceed in these circumstances:
•For playing alone, you can use the Video Quality menu or Video Display settings to ease the
playback demands by reducing the display quality of the video. For more information, see
“Options for Controlling Real-Time Effects Playback” on page 156.
•For output, where anything less than the best quality is not an option, you can use the
ExpertRender feature to identify the minimum number of effects that you must render in
order for the sequence to play in real time. For more information, see “ExpertRender” on
page 160.
Color Coding on Effect Icons
Effect icons in the Effect Palette and in the Timeline display colored dots to help you determine
whether an effect is real-time or non-real-time.
Real-time effects show a green dot. Real-time effects play in real time in a sequence, subject to
the playback capabilities and constraints of your Avid editing system. For more information, see
“Real-Time Playback of Video Effects” on page 153.
24
Understanding the Effect Palette
Non-real-time effects have no dot in the Effect Palette. In the Timeline, the effect icon shows a
blue dot until you render the effect.
In the Effect Palette (left), green dots indicate real-time effects. (Real-time effects might not be playable in real time
depending on system resources and the complexity of your sequence.) Non-real-time effects have no dot in the
Effect Palette. Non-real-time effects have a blue dot in the Timeline (right) until they are rendered.
All colored dots disappear in the Timeline when you render effects.
Understanding the Effect Palette
The Effect Palette lists all transition and segment effects, and some motion effects, that are
available for your Avid editing application. The Effect Palette is the primary tool that you use to
apply effects to your sequences. For information on accessing the Effect Palette, see “Displaying
and Adjusting the Effect Palette” on page 26.
The left side of the Effect Palette displays a list of effect categories. The right side shows the
various effects that are available for the currently selected effect category.
The Effect Palette displays all of the effect categories available for your Avid editing application,
including any third-party AVX plug-in effects you have installed. If you save any effect
templates to a bin, and have that bin open, those templates also display in the Effect Palette. For
reference information on all Avid effects, see “Effects Reference” on page 562.
25
Displaying and Adjusting the Effect Palette

Working with Effects in HD and in Progressive Frame Projects
Working with Effects in HD and in Progressive Frame
Projects
Many video effects work the same way regardless of the project type or video format. This topic
describes several situations where effect behavior varies depending on whether a project is SD or
HD, or is interlaced or progressive.
Effects Considerations for HD Projects
Effects that use square geometry automatically use the correct pixel aspect ratios. These effects
include Titles, Box Wipes, and certain paint modes like Mosaic. Effects such as Color
Correction, Color Effect, and Luma keys automatically use the correct color space (ITU-709 for
HD).
The Safe Color Limiter effect converts from 709 to 601 color space before limiting unsafe colors,
n
and then converts back to 709 color space. For more information, see “Understanding the Safe
Color Limiter Effect” on page 838.
Note the following:
•You do not need to generate 4:3 media for titles.
•Timewarp effects use a 60p input and output format in 720p/59.94 projects.
Effects Considerations for Progressive Frame Projects
Effects in progressive frame projects are frame based rather than field based, so their normal
behavior is slightly different from effects in interlaced projects. In particular, temporal artifacts
might appear in some effects under certain circumstances. This topic explains when temporal
artifacts might appear and suggests ways to create effects that do not show perceptible temporal
artifacts.
Effects that do not involve any movement across the screen — for example, masks, Color
Effects, and dissolves — always look the same in progressive projects as they do in interlaced
projects.
Effects that involve movement across the screen — for example, wipes, 3D shapes, or moving
titles — might look different in 24p or 25p projects from their equivalents in interlaced projects
for the following reasons:
•Because the effect uses 24 or 25 progressive frames per second (24p or 25p), motion across
the screen is interpolated in 24 or 25 increments per second. (Contrast the 50 increments per
second for a PAL interlaced project or the 60 increments per second for an NTSC interlaced
27
Working with Effects in HD and in Progressive Frame Projects
project.) For example, the edge of a 1-second Horizontal Edge Wipe effect appears in 24 or
25 different positions across the screen. For effects of short duration in particular, this
difference might be perceptible to the viewer.
•When the 24p or 25p media is output (to the interlaced Client monitor or as a digital cut), it
is interlaced again and pulldown is inserted to achieve 60 fields per second (NTSC). Your
Avid editing application inserts pulldown by duplicating some of the existing frames to
create the correct number of fields per second. Viewers might notice temporal artifacts
created by this duplication process. This behavior is a normal result of the pulldown
insertion process and is often perceptible in conventional transfers of films to video formats.
PAL output with pulldown also duplicates certain frames but is less likely to exhibit perceptible
n
temporal artifacts since fewer frames require duplication.
Motion effects that you create in 24p or 25p projects, such as Variable Speed effects, might also
look different from motion effects that you create in interlaced projects. For more information on
24p or 25p motion effects, see “Considerations for Motion Effects in Progressive Projects” on
page 211.
For more information on how your Avid editing application handles 24p or 25p material, see
n
“Displaying 24p and 25p Media” in the Help.
If an effect in a 24p or 25p project does not look completely smooth, do one or more of the
following:
•Slow down the effect.
For example, a 2-second Horizontal Edge Wipe effect, while it is still performing at the same
rate (24 increments per second), moves across the screen in 48 steps. These smaller
movements make the wipe appear smoother to the viewer.
•Soften the edges of the effect.
The more the edges of the effect are blurred, the less noticeable are the movements between
the increments of the effect.
•When working with moving titles, avoid small font sizes and sharp edges.
In a moving title such as a roll, lines of small text might move less smoothly than lines of
larger text.
In a 24p or 25p project, if you select Output to DV Device from the Video Quality menu in the
n
Timeline, the Realtime Encoding option is automatically turned off. For more information, see
“Playing Back to a DV Device” in the Help.

Changing Timeline View Settings for Effects
Changing Timeline View Settings for Effects
All effect icons display in the Timeline by default. You can change the Timeline settings to
display all effect icons, all effect icons except Dissolve Effect icons, or no effect icons. If you
change the setting to display no effect icons, you must reset it before you begin applying effects.
The fewer effect icons you display, the faster your Avid editing application refreshes the screen.
To change the Timeline settings:
1. In the Timeline window, click the Fast Menu button, and then do one of the following:
tTo display all effect icons in the Timeline, select Effect Icons.
tTo display all effect icons except Dissolve icons, select Effect Icons and deselect
Dissolve Icons.
tTo display no effect icons, deselect Effect Icons. Dissolve Icons appears dimmed and is
now unavailable.
2. (Option) To save your Timeline settings, click the Timeline View Name button, select Save
As, and type a view name.
Timeline View Name button and menu below Timeline
Adjusting Trim Settings for Effects
In Trim mode in some Avid editing applications, you can control whether or not the effects you
apply are computed immediately on the screen (that is, on-the-fly) or appear later when you
render them. For example, viewing transitions as cuts (without rendering on-the-fly) can make
trimming easier.
For more information on changing Trim settings, see “Trim Settings Basics” in the Help.
n
To change the Trim settings for Render On-the-Fly:
1. In the Project window, click the Settings tab.
The Settings list appears.
2. Double-click Trim.
The Trim Settings dialog box opens.
3. Click the Features tab, and then select or deselect Render On-The-Fly.
4. Click OK.

Setting Effect Grid Options
You can display a grid in the Effect Preview monitor in Effect mode to guide you as you create
and adjust effects. For information on using the grid, see “Understanding the Effect Grid” on
page 80.
The Grid Settings dialog box lets you customize the grid.
To set the default grid values, do one of the following:
tIn the Settings list of the Project window, double-click Grid.
tIf the effect you are working with has a Grid parameter group, click the Other Options
button for the Grid parameter group in the Effect Editor.
The Grid Settings dialog box opens.
For information on the Grid Settings options, see “Grid Settings” in the Help.
Setting Effect Aperture Options
In some Avid editing applications, the Effect Aperture setting lets you control the number of
horizontal lines of an image that are used to create an effect. For example, if you are working
with DV media and notice black lines above and below Picture-in-Picture effects, you can
instruct the system to ignore the lines by changing the effect aperture.
Setting Effect Grid Options
The Effect Aperture feature applies only to NTSC projects.
n
For uncompressed and non-DV resolutions, your Avid editing application uses all 243 horizontal
lines per field to display the image. For DV media, your Avid editing application uses 240 lines
for the image and adds two black lines above the image and one black line below the image. The
effect aperture lets you decide whether or not to use the three black lines when you create effects.
In a DV project the black lines can become visible when you create effects such as
Picture-in-Picture or Squeeze effects.
The following illustrations show four PIP effects. In the first illustration, which uses the default
ITU 601 aperture, you can clearly see the black lines between the effects. The second illustration
displays the same media with the DV25 effect aperture — the black lines do not appear between
the effects.
