Synchronize and compare multiple videos on a Mac

Supra Player is a Mac app for comparing and reviewing several videos in one workspace. Users can load multiple camera angles or versions of an edit, synchronize them using their audio, and play or scrub through the clips together. Grid, single-video, and freeform canvas layouts support different kinds of review.
The app includes an A/B comparison slider, linked zoom, annotations, and controls for adjusting each clip's starting position. Reviewers can mark in and out points, trim a section, and export the current layout as a video. Supra Player suits editors, creators, and post-production teams comparing takes, color grades, visual effects, or synchronized camera footage.
