COMPARE WITH PRECISION

Compare the same moment—not a best guess.

For sports, training, rehearsal, music, and dance. Align two movements at a shared reference point and inspect the difference with your own eyes.

01 / SYNC

Reference-point sync

Mark impact, foot strike, or another key moment in each video. Play, pause, seek, and step through both on one timeline.

02 / VIEW

Three comparison views

Compare side by side or stacked. Overlay both videos and tune position, scale, rotation, and opacity.

03 / DETAIL

Inspect and export

Use slow playback, precise frame stepping, and loop ranges. Save the result as an image or MP4 video.
