Use hyperframes beats when an existing HyperFrames project needs the Studio-compatible beat file for its music track. This is a CLI utility, not a complete video workflow.
npx hyperframes beats
npx hyperframes beats ./my-video
npx hyperframes beats ./my-video --jsonThe project must contain a local music <audio> source. Mark it with data-timeline-role="music"; an id containing music, bgm, or soundtrack is also recognized. The command analyzes that file in headless Chrome and writes beats/<audio-relative-path>.json.
If no beats are detected, the command fails and writes nothing. If Chrome is unavailable, run:
npx hyperframes browser ensureFor a complete beat-synced video, route through /music-to-video. That workflow owns a different audio-driven pipeline and its audiomap.json; do not replace its analyzer with this Studio utility.
