reelbench-skills
A video-side Claude Code / Codex skill: shot-by-shot film analysis where ffmpeg measures every cut and the report must clear 14 quality gates.
reelbench-skills currently ships video-shots, a 拉片 (film-breakdown) skill that turns a finished video into a per-shot analysis table — duration, shot size, category, camera movement, frame. Cut points and durations are measured by ffmpeg/ffprobe; the model only judges the four things a model should judge, and 14 quality gates reconcile the report line by line. The output is a single self-contained interactive HTML page: embedded player that highlights shots in sync and jumps on click, a rhythm strip, a searchable/filterable/sortable shot table with first-and-last keyframes per shot, statistical distributions, and the quality checks. The bundled demo was produced from a 202.9-second AI short: 53 shots, average 3.83 seconds, 15.7 cuts per minute, all 14 gates green. Zero npm dependencies, zero API keys; needs node >= 18 and ffmpeg/ffprobe. Apache-2.0, bilingual.
What it does
- Cut points and durations measured by ffmpeg/ffprobe — the model only judges shot size, category, camera movement and frame content
- Every report must clear 14 quality gates, reconciled line by line before it ships
- Output is one self-contained interactive HTML page — embedded player with synced shot highlighting, rhythm strip, searchable and sortable shot table with per-shot keyframes
- Zero npm dependencies and zero API keys, running on your current session quota; installs by symlink so a git pull takes effect immediately
When to use it
Breaking down reference films, competitor video ads or your own footage into checkable shot data — pacing, cut density and camera patterns as evidence instead of vibes.
Getting started
git clone https://github.com/eternityspring/reelbench-skills.git cd reelbench-skills ./scripts/install.sh # symlinks into ~/.claude/skills and/or ~/.codex/skills # ./scripts/install.sh --claude only Claude Code # ./scripts/install.sh --codex only codex # ./scripts/install.sh --uninstall # deps: node >= 18, ffmpeg/ffprobe (macOS: brew install node ffmpeg)
Things to know
One skill in the pack so far (video-shots), first published September 2026 — the README frames it as the start of a video-side toolkit. ffmpeg and ffprobe must be on PATH, or the measured columns can't exist.
