Frame nudge
Frame nudge moves the video alignment offset by exactly ±1 frame at a time. Use it after auto-align when the video is close but not quite on the cut or beat — a single frame of drift is often visible and audible when the video audio and the reference audio are compared carefully.
The nudge buttons
In the Video Reference panel header, two buttons with left and right arrow icons nudge the video alignment:
- Left arrow (−1 frame) — shifts the video one frame earlier relative to the audio.
- Right arrow (+1 frame) — shifts the video one frame later relative to the audio.
The current offset value displayed in the panel updates after each press.
Frame size
One frame corresponds to the duration at the project's current frame rate. At 25 fps a frame is 40 ms; at 29.97 fps a frame is approximately 33.37 ms. The nudge button always moves by exactly one frame in the active frame rate.
What nudge does not do
Frame nudge applies an additive offset on top of whatever alignment is currently set. It does not re-run the waveform comparison — if you want to redo the automatic alignment, click Re-sync to audio instead and then nudge from there if needed.
Workflow
The recommended workflow is: import → let auto-align run → check the result visually in the panel → nudge ±1 frame until the video cut lines up with the waveform feature you expect. Typically two or three nudges are enough to correct a sub-frame auto-align error.
