Beat Mask: tap a subject once and effects play the person instead of the whole frame, locked to the kicks and snares of your track, with the background left untouched.

Problem: beat-sync editing tools flash or cut the entire frame. Creators who want an effect on the subject, on the beat, have to rotoscope by hand.

How it works: 1) Load a short clip and a track. 2) Tap the subject on frame one. The tap goes to SAM 3.1 through the Meta Model API as a point prompt, and SAM segments and tracks that subject through every frame. 3) The track is analysed for kicks, snares and tempo. 4) Pick an effect, or type a vibe such as "make it aggressive" and Muse Spark returns an effect plan (effect, which drum drives it, intensity). 5) Effects: glow (kicks), color flash (snares) and stutter (every beat), applied only inside the feathered subject mask. 6) The export checks itself before it is handed over: six checks (format, subject present, background untouched, effect lands on every beat, subject not lost, mask does not flicker or slip), with up to 3 re-renders using stronger mask smoothing, then a human signs off on the exact file hash.

Built solo by Garrick Jordan, with Muse helping: a bit of both. Local Python app, MIT license. A Reel Studio module.
