What is rea-video?
rea-video is a command-line tool that breaks down any video frame by frame to determine how it was produced. It classifies each shot as live footage, AI-generated, or code-based, then explains the specific techniques used for visuals, captions, editing, and audio. The tool outputs structured reports in English or Chinese and provides a step-by-step plan to recreate the video yourself.
It analyzes multiple video formats including talking-head recordings, AI short dramas, 3D animations, motion graphics, and mixed edits. For each segment, it identifies camera setups, lighting, color grading, text styling, cut timing, and audio sources. Captions and styled text are extracted with precise timestamps and exported to SRT or ASS formats. Audio analysis covers voice type, music BPM, and sound effect placement.
The project is designed to run inside AI coding agents like Claude Code or Codex. Users can point it at a local video file, and the agent handles installation, workflow execution, and report generation. It requires Python 3.10+ and ffmpeg. Detailed documentation is available in the repository.
