Timeline Track Area
The main part of the Timeline, to the right of the Timeline layers list, is called the track
area. Each objects in a project is represented by a colored bar (known as a timebar).
Different colors represent different types of objects. For example, behaviors and filters
are purple and masks are gray. For a complete table of colors, see Timeline Tracks.
When a group containing more than one object is selected, the group track displays an
indicator that identifies how many objects reside in that group. Layers, cameras, and
lights are counted in that total. Effects such as masks, behaviors, and filters are not counted.
Timeline Ruler
At the top of the track area is the ruler that provides a gauge for the positions and
durations of objects in your project.
In point
Playhead
Project marker
Out point
The ruler can contain indicators to help mark important frames or sections of the project
such as the playhead, play range indicators (also called In and Out points), and markers.
The ruler can be viewed in frames or timecode.
