Working with Multiple Tracks
Your Avid editing application lets you edit up to 24 tracks of video and 24 tracks of audio,
including multichannel audio tracks, and one data track. 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.
Multichannel audio tracks contain more than one channel of audio in a single track. Stereo
multichannel tracks, for example, contain two stereo channels in one track. You can edit
multichannel audio tracks in the same way that you edit mono audio tracks.

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.
Occasionally, effects editing involves a procedure known as nesting. Nesting involves stepping
into existing tracks to reveal added layers for combining multiple images and digital video
effects. When you apply an effect, you can step out to view and render the effect as one segment
on the track. You can nest up to 24 additional tracks within each track.

Understanding the Track Selector Panel
The Track Selector panel provides a quick display of track information. You can see which tracks
are available, active, patched, monitored, or locked on the source and record sides at any time.
The Track Selector panel can look very different depending on the nature of the source material
or the work underway in the sequence. The following configuration shows only one example.

You cannot patch a data (D) track.
