Free to try. iPhone, iPad and Mac - one Pro purchase covers all your devices.

How it works

1. Load two clips

A reference attempt and the one you want to compare.

2. Mark the same instant

Scrub each clip to the same moment (for example, take-off) and press Mark. The timelines lock together.

3. Play them as one

Sync playback, slow motion, frame-by-frame, and a blend slider.

4. See the difference

Normal ghost overlay, Lighten, or Difference to light up exactly where the two diverge.
