122 Chapter 7 Timeline Playback, Navigation, and Editing
Basic Timeline UI Elements
The Timeline is divided into a number of tracks, containing the shots, grades, and
keyframes used by your program.
 Render Bar: The render bars above the Timeline Ruler show whether or not a shot is
unrendered (red), or has been rendered (green).
 Timeline Ruler: Shows a time scale for the Timeline. Dragging within the Timeline
ruler lets you move the playhead, scrubbing through the program.
 Playhead: Shows the position of the currently displayed frame in the Timeline. The
position of the playhead also determines the current shot that’s being worked on.
 Video Tracks and Shots: Each shot in the program is represented within one of the video
tracks directly underneath the Timeline Ruler. Color only allows you to create up to five
video tracks when you’re assembling a project from scratch, but will accommodate
however many superimposed video tracks there are in imported projects.
Note: Color does not currently support compositing operations. During playback,
superimposed clips take visual precedence over clips in lower tracks.
 Track Resize Handles: The tracks can be made taller or shorter by dragging their resize
handles up or down.
 Lock Icon: The lock icon shows whether or not a track has been locked.
 Grades Track: Color allows you to switch among up to four primary grades applied to
each shot. This lets you quickly preview different looks applied to the same shot,
without losing your previous work. Each grade is labeled Grade 1–4.
