Editing Controls
The Timeline editing controls determine which tracks are selected and enabled for
editing and playback.
 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 “
 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 Express HD 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 “
