Editing Controls
The Timeline editing controls determine which tracks are selected and turned on for
editing and playback.
Destination control
Track Visibility control
Source control
Auto Select control
Lock Track control
Locked tracks are
cross-hatched.
• Source and Destination controls: These allow you to connect (or patch) clip items of the
source clip in the Viewer to tracks in the Timeline. These controls are primarily used in
three-point editing to determine which source clip items’ tracks are edited into your
sequence, and where they are placed.
The number of available Source controls corresponds to the number of clip items of
the source clip currently open in the Viewer. For example, a typical DV clip has one
video track and two audio tracks. In this case, one video and two audio Source controls
appear in the Timeline. If, instead, you open a clip in the Viewer that has one video
item and four audio items, then one video and four audio Source controls appear in
the Timeline. For more information, see
“Three-Point Editing.”
• Track Visibility control: Determines whether the contents of a track are displayed and
rendered in your sequence. When a track is disabled, it appears darkened in the Timeline,
but its contents remain in your sequence and can still be edited. When you play back
your sequence, disabled tracks don’t appear in the Canvas or on an external monitor,
nor will they be rendered or output to tape with that sequence.
Note: Render files for a track are deleted if the track is disabled. You can have
Final Cut Pro display a warning before this occurs by selecting the “Warn if visibility
change deletes render file” option in the Editing tab of the User Preferences window.
For more information, see
“Choosing Settings and Preferences.”
