Rea Video

Rea video is an open source command-line tool that reverse-engineers any video shot by shot to generate recreation plans.

Rea video is a tool designed for AI assistants to reverse-engineer videos. It processes live action, AI video, digital humans, 3D animations, code motion, screen recordings, and mixed media. The tool splits videos by shots, analyzes visual elements, subtitles, text graphics, editing pace, and audio, and outputs a complete HTML report. It runs via agents in environments like Claude Code or Codex, requiring ffmpeg and Python 3.10 or higher. Users can configure vision models like Gemini or Doubao for higher accuracy and prompt generation. It helps creators learn video structure, lighting, camera angles, and rendering methods.
