rea-video is built for AI agents. In Claude Code, Codex or any agent that can run commands, say:

Install https://github.com/JuneYaooo/rea-video, then break down this video: /path/to/video.mp4

The agent installs the CLI, learns the workflow and runs the whole thing. You need ffmpeg and Python 3.10+.

<details><summary>Install by hand</summary>

brew install ffmpeg            # or: sudo apt install ffmpeg
git clone https://github.com/JuneYaooo/rea-video && cd rea-video
bash scripts/install_skill.sh  # installs the CLI (pip, or pipx / a local .venv if pip is blocked) and links the skill into ~/.claude, ~/.codex, ~/.agents
rea-video --help

You get:

• a one-line summary, e.g. "41% AI video + 59% code UI, 8 s of real screen recording, library music at 122 BPM"
• a remake plan, split into what to film, what to generate and what to code
• a full report.html with per-shot frames, evidence, prompts, camera and lighting notes, and the audio breakdown

Add a video-capable model — Gemini or Doubao both work: give the agent the endpoint and key. It makes live/AI/3D calls more accurate and writes a reverse-engineered prompt for every shot. Without one it still works; if your agent can see images, it will check the uncertain shots itself.
