The clip overwrites other items on the destination tracks for the duration of the edit,
and uses the default transition.
Performing a Replace Edit
A replace edit is a specialized form of overwrite edit. A replace edit places the frame at
the current Viewer playhead position at the Canvas/Timeline playhead location in your
sequence. You can use a replace edit to:
 Edit a clip into your sequence so that the current frame in the Viewer is placed at the
current playhead location in your sequence
 Quickly replace an entire shot that’s already in your edited sequence
 Resynchronize a video or audio clip item with an unlinked clip item in an adjacent track
For example, if you have two clips, each of which shows a different camera angle of the
same action, you may decide you want to replace the shot currently used in the
Timeline with the other angle. You can place both the Viewer and Timeline playheads
on frames where the action matches in each shot, and then replace the sequence clip
with the clip from the Viewer.
