reelbench-skills reached 249 stars in a day by letting ffmpeg do the measuring and the model only the judging
eternityspring/reelbench-skills was created 2026-09-11 and had 249 stars and 30 forks by 2026-09-12. It packages two Claude Code and Codex skills: `video-shots` breaks a finished video into a per-shot analysis table of duration, shot size, category, camera movement, framing and pacing, and `video-sync` renders the video beside a shot list that scrolls and highlights in sync with cuts. The design note worth stealing is that cut points and durations are measured by ffmpeg while the model judges only what requires judgment, with 15 quality gates reconciled one by one; dependencies are just node 18+ and ffmpeg.
