Track Area
The main part of the Timeline, to the right of the Timeline layers list, is called the track
area. Objects in your project are each represented by a colored bar. Different colors
represent different types of objects. For example, behaviors and filters are purple and
audio layers are green. For a complete table of colors, see “
Group tracks differ from individual object tracks in two ways. First, when an object that
resides in a group is selected, a thinner group bar appears above the layers within the
group. Second, when the group itself is selected, the group track displays a special
indicator that identifies how many objects reside within that group. Layers, cameras,
and lights are counted in that total; effects such as masks, behaviors, and filters are not
counted in that total.
You can collapse a group track so the tracks for the individual objects within the group
are temporarily hidden.
