How to Break Down Any Video With rea-video

You watch a video, it hits, and you have no idea how it got made. Real footage, AI, or some editing trick — nobody can tell anymore. rea-video is an open-source tool that ends the guessing, and it caught an AI music video that a vision model had already called real footage.

It is free, it runs offline, and it does not stop at a verdict. Drop in a TikTok, an ad, or an AI music video and it reports every shot as filmed, AI-generated, or built with code, then hands you a remake plan split into what to film, what to generate, and what to code.

What You Need

• Claude Code or Codex already installed, since the tool runs inside one of them.
• The video file on your machine, plus its path, like /path/to/video.mp4.

Tutorial

1. Open Claude Code or Codex. rea-video runs inside either one, and it is free and works offline.
2. Paste the repo URL into the chat and ask it to install. That single install request is the whole setup step.
3. Type break down this video: /path/to/video.mp4, with the real path to your own file in place of the placeholder.

Wrapping Up

What lands in your hands is a one-line verdict, a full report with a screenshot of every shot, and a remake plan split into what to film, what to generate, and what to code. The report also covers the cuts and pacing, subtitle and text styling, whether the voice is real or AI, and whether the music came from AI or a stock library, down to the BPM. Run it on that video you keep replaying, then go make your own version better.
