How it ranks: per-frame audio energy, onset density, dynamic range, and voice activity, the same signal stack our beat-sync engine uses, retuned for hype detection.

100% in-browser: your video never leaves your machine. Web Audio analyses the soundtrack, ffmpeg renders the crops. No upload, no servers.

Tip: 10-30 minute videos finish in 30-90 sec on a recent laptop. Long videos work, just take proportionally longer to render the chosen clips.
