Create instant replays
You can apply an instant replay to a range selection within a clip or a whole clip. Final Cut Pro duplicates the range or clip, appending the duplicated frames to the end of the selection as a new segment. You can then modify the speed of the new segment to achieve the instant replay effect you’re looking for.
Create an instant replay
Choose Instant Replay from the Retime pop-up menu in the toolbar.
A duplicate of the range or clip is appended to the end of the selection and plays back in forward motion at the selection’s original speed. (By default, the instant replay is set to play back at 100 percent speed.)
If you want to adjust the speed of the instant replay segment, drag the retiming handle to the left to increase the speed or to the right to decrease it.
To see the instant replay effect, play back the original selection and the instant replay segment.
