What is it?

reelbench-skills is a set of three agent skills for Claude Code and Codex that work with video files. The video-shots skill turns a finished film into a shot-by-shot table with duration, shot size, camera move, frame description and rhythm role. Cut points and durations are measured with ffmpeg, while the model only makes the judgments that need interpretation.

video-sync composites the footage with its shot data: the video plays on one side while the current shot's details appear on the other, switching at each cut and highlighting the active row in the list. video-scrub rebuilds a video as a clean file that keeps only picture and sound, removing GPS, device info, account IDs and telemetry tracks, including data that ffprobe cannot display.

The skills are installed by symlinking them into ~/.claude/skills/ or ~/.codex/skills/. They require node 18 or later and ffmpeg/ffprobe, with no npm dependencies and no API keys.

Key features

  • 01Breaks a video into shots with duration, shot size, camera move and frame description.
  • 02Measures cut points and durations with ffmpeg rather than estimating them.
  • 03Syncs video playback with a shot data panel that highlights the current shot.
  • 04Strips GPS, device, account and telemetry metadata while keeping picture and sound.
  • 05Generates an interactive HTML report that works offline.

Use cases

  • Analyzing the pacing and shot structure of a finished short film or ad.
  • Reviewing shot-by-shot breakdowns alongside footage for editing or study.
  • Removing identifying metadata from video before sharing it publicly.

Quick start

  1. 1

    Clone the repository

    git clone https://github.com/eternityspring/reelbench-skills.git
  2. 2

    Enter the project folder

    cd reelbench-skills
  3. 3

    Install the skills by symlinking them

    ./scripts/install.sh

Things to know

  • Requires ffmpeg and ffprobe installed separately, plus node 18 or newer.
  • Works as Claude Code or Codex skills, so it needs one of those tools.
