Scrub both clips frame by frame, drop key moments on each, and tap a number to jump both videos to the same action. The gap shows itself.
Frame by frame
Both moves. One screen.
Your clip and the reference, side by side or stacked. A CapCut-style filmstrip sits under each clip with a fixed playhead — drag through time, pinch to zoom from the full clip down to a single second.
Key moments
Line up the same move.
Mark up to 10 key moments on each clip and name them your way. Tap a number and both videos jump to the matching action instantly.
AI Skeleton
See the shape of every move.
Overlay an AI skeleton on your clip and export it in three styles: skeleton only, translucent, or on the real background.
Every sport
Bouldering to golf.
Climbing, swimming, running, tennis, weightlifting, skating, dance, golf — anywhere the same move shows up twice. Landscape or vertical, every aspect ratio works.
