rea-video

Breaks down any video shot by shot to show how it was made and how to remake it.

New this week

What it does

rea-video looks at a video and works out how each shot was made. It tells you whether a shot was filmed for real, generated by AI, built in 3D, made with code, or captured from a screen. It also covers captions, stickers, cuts, voices, music and sound effects.

It cuts the video into shots, separates voice, music and effects, and gathers clues such as camera noise, frame timing and hidden AI tags. Where clues conflict, the AI assistant running it checks those shots by eye. You get a one-line summary, a remake plan split into what to film, generate and code, and a full report page with frames and notes.

It is designed to run inside AI coding assistants such as Claude Code or Codex. Adding a video-capable AI model such as Gemini or Doubao makes its calls more accurate and lets it write an AI prompt for every shot, but its makers say it still works without one.

Who it's for

Video creators, marketers and curious viewers who want to know how a clip was made, or who want a plan to make something similar.

Can I use it without coding?

With some setup. You ask an AI assistant like Claude Code or Codex to install and run it, or install it by hand with a few commands plus ffmpeg and Python. New to this? Start here.

Can I run it?

Cost
Free, but needs an AI accountThe software is free, but it uses an online AI service (like OpenAI or Anthropic), which usually charges for use.
Runs on
Mac, Linux

Your choice: run it on your device or use an online service

Try it

  1. Open an AI assistant that can run commands, such as Claude Code or Codex.
  2. Make sure ffmpeg and Python 3.10 or newer are installed.
  3. Ask the assistant to install rea-video from its GitHub page and break down your video file.

Using Claude Code, Cursor or another AI coding assistant? Paste the prompt and it will walk you through the setup.New to this?
