Override Face Tracking: Manual Crop and Custom Keyframes

Automatic face tracking gets the crop right most of the time, but sometimes you want to override it — center on a specific detail, shift the frame to include a second person, or hold a position the algorithm didn't choose. Bitcut lets you manually adjust the crop at any point after analysis.

Drag to Reposition

The simplest adjustment is dragging the crop in the preview:

1

Enter face tracking mode

Select a clip and tap the Face button to open face tracking. The preview shows the current vertical crop.

2

Scrub to the moment you want to adjust

Move the playhead to the exact time where you want a different crop position.

3

Drag the preview to shift the crop

Drag horizontally on the preview to reposition the vertical frame. A new keyframe is created at the current time with your chosen position.

Adding Custom Keyframes

When you drag the crop, Bitcut automatically inserts a keyframe at the playhead position. This keyframe overrides the automatic tracking at that moment. The camera will smoothly transition from the previous keyframe to your custom one, then continue to the next.

You can add as many custom keyframes as needed. Each one appears as a diamond marker on the face strip.

Hold a position. To keep the crop fixed for a section, add two keyframes at the same position — one at the start and one at the end of the section you want to lock. The camera will hold steady between them.

Resetting to Automatic

If your manual adjustments aren't working out, you can re-run analysis to regenerate all keyframes from scratch. Tap Re-analyze in face tracking mode. This discards all manual keyframes and rebuilds tracking from the original face data.
