4 Without moving the Timeline playhead, press the F key to perform a match
frame operation.
This opens the master clip that the video clip in your sequence came from in the
Viewer, placing the playhead in the Viewer over the same frame that was under the
playhead in the Timeline. For more information on match frame editing, see “
Matching
Frames Between Sequence and Master Clips ” on page 430.
5 Move the playhead in the Viewer to the new frame that you want to align with the
audio cue that you selected in the Timeline.
6 Now that the Timeline playhead is lined up with the audio cue in your sequence and
the Viewer playhead is lined up with a video frame that you want to sync to it, perform
the edit by doing 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.
The original video clip item in your sequence is replaced with a new copy of the clip,
which is synchronized with your audio cue.
