162 Part II Rough Editing
4 Do one of the following:
 Drag the clip from the Viewer to the Replace section of the Edit Overlay in the Canvas.
 Click the Replace button in the Canvas.
 Press F11.
Important: Make sure that the clip in the Viewer contains enough media on either side
of the playhead to fill the duration of the clip you want to replace in the Timeline. If it’s
not, you’ll see an “Insufficient content for edit” message.
Another common use of the replace edit is to line up a frame in a clip that’s already in
your edited sequence with an audio cue in an adjacent clip. For example, if you have a
video clip of a man dancing and an audio clip in another track of music, you can use a
replace edit to place a different portion of the same video clip into your sequence at
the same location, aligning a frame showing a particular movement of his foot with a
particular beat of the music.
