Playback Loop
The playback loop lets you replay a passage continuously -- ideal for fine-tuning subtitle timing on a specific moment, or for checking the synchronization of fast dialogue.
Creating a loop
There are several ways to define the loop region:
From a selection -- select one or more subtitles and press L. The loop covers the span from the first to the last selected subtitle.
From the playhead -- pressing L without a selection creates a 10-second loop around the current position (5 seconds before, 5 seconds after).
Manually on the ruler -- Cmd + drag on the timeline ruler to draw a loop region with the exact dimensions you need.
Using IN/OUT shortcuts:
| Action | Shortcut |
|---|---|
| Set loop start | Opt + [ |
| Set loop end | Opt + ] |
| Toggle loop on/off | L |
During looped playback
When the playhead reaches the end of the region, it automatically jumps back to the beginning. The loop is visible on the timeline as a colored zone, with handles at each end for adjusting the boundaries by dragging.
Using the loop for export
If a loop is active when starting a video export, Scene Cut offers the choice between exporting the full video or only the looped portion -- handy for sending a short clip for approval.
