Tracks

Every item in the Track View hierarchy has a track that displays what happens to the item over time.

There are two types of tracks:

• Range tracks indicate when items below the track are animated. A range bar in the track displays the range of time over which the animation occurs.
• Animation tracks contain the actual animated values for an item. Only controller items have an animation track.

The values in an animation track are usually displayed as keys. Some controllers don’t use keys and instead display their values as a range bar or some other graphic symbol. For example, the Wave Form item displays a sound file as a two-channel sound wave.

Animation tracks are also the only track type that can be displayed as a function curve.

Tracks also appear in Video Post, where they are used to show the time values of the events that make up the Video Post queue.
