Working with Multiple Tracks
As your project progresses, you might need to add and edit with addi-
tional audio or video tracks. The Avid system allows you to edit up to
24 tracks of video and 24 tracks of audio. In addition, you can step into
tracks to create additional tracks for nested effects.
While working with multiple tracks, you can use the Track Selector
panel to select, manipulate, delete, lock, patch, and monitor your
tracks. You can use multiple tracks to layer audio effects and sound,
or to add video titles and other effects, as described in this section.

Multiple video tracks do not immediately play back at the same time until you
apply an appropriate effect that composites the layers. Multiple audio layers,
however, do play back immediately if correctly monitored.
About Effects Editing
Your primary use for multiple tracks of video is in the use of effects.
Effects editing techniques in the Avid system fall into the following
basic categories:
• Motion effects, such as freeze-frame and slow-motion or fast-
motion effects, involve applying frame-motion parameters to
selected footage, usually on a single video track.
• Transition effects, such as dissolves and wipes, involve making the
transition from one edited clip to another on the same video track.
• Segment effects, such as picture-in-picture, keys, or color effects, are
applied to whole segments. These often require multiple layers of
video.

Composer Effects Guide.
