Slow Motion

Apply slow motion effect to an overlay.

How It Works

Provide speed_multiplier < 1.0 for slow motion. 0.5 = half speed, 0.25 = quarter speed. Backend computes exact frames.

More Editor Core Tools

Change Speed
Change the playback speed of an overlay.
Batch Speed Change
Apply a speed change to multiple overlays at once.
Move Overlay
Move an overlay to a new start position on the timeline without changing its duration. Pushes neighbors on the same row.
Extend Duration
Increase an overlay's duration by a delta. Pushes neighbors on the same row.
Shorten Duration
Shorten an overlay by removing a number of seconds/frames from the end. Use this when user says 'make shorter', 'reduce duration', 'shorten by X seconds'. Do NOT use trim_to_playhead for this — trim_to_playhead is only for cutting at the playhead position.
