The JKL shuttle is DaVinci Resolve-style: tap L (or J) again to go faster. It behaves identically in the full app, on a selected canvas clip, and in fullscreen.
Scrubbing
Section titled “Scrubbing”Drag the timeline to scrub. You can free-scrub while paused, and playback stays smooth on large or 4K clips thanks to an in-memory proxy. Press play after scrubbing on a zoomed-in timeline and the view recenters on the playhead.
Disk frame cache
Section titled “Disk frame cache”The player also builds a frame cache on disk in the background. The job leaves 2 CPU cores free and runs ffmpeg at below-normal priority, so scrubbing and playback stay responsive while the cache builds.
Use it when: you open a long 4K master and want to start reviewing immediately.
Zoom & fit
Section titled “Zoom & fit”| Action | Key |
|---|---|
| Toggle Fit to window ↔ 100% (actual pixels) | F |
| Zoom in / out | + / − |
| Reset zoom | 0 |
