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.
1 Effects Concepts and Settings
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
22
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 195.
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 379.
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 359.
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 249.
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 249.
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 279.
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 305.
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 539.
23
1 Effects Concepts and Settings
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 183.
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.
24
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 25.
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 149.
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.
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 150. You have
several options for how to proceed in these circumstances:
•For playing alone, you can use the Video Display settings to ease the playback demands.
For more information, see “Options for Controlling Real-Time Effects Playback” on
page 151.
•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 156.
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 149.
Color Coding on Effect Icons
Relationship color corrections (Symphony only) are also real-time effects that display in the
n
Timeline with a green dot. For more information, see “Displaying Color Correction
Information in the Timeline” on page 768.
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.
25
1 Effects Concepts and Settings
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 559.
Displaying and Adjusting the Effect Palette
This topic provides basic information on displaying and adjusting the Effect Palette. For
information on the organization and purpose of the Effect Palette, see “Understanding the
Effect Palette” on page 26.

effect category list and the templates in that bin appear on the right.
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 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
n
colors, and then converts back to 709 color space. For more information, see
“Understanding the Safe Color Limiter Effect” on page 913.
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 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.
Changing Timeline View Settings for Effects
PAL output with pulldown also duplicates certain frames but is less likely to exhibit
n
perceptible 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 207.
For more information on how your Avid editing application handles 24p or 25p material, see

“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.
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
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.

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 81.
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.
