A local, prompt-driven motion-design editor. Every scene is a small piece of code; you change it by chatting with Claude Code or Codex next to a live preview, down to the millisecond. Finished videos export to MP4.

Inspired by Caleb Porzio's tweet about the editor he vibe-coded for his video.

• Chat per scene, or about the whole video, next to a live preview.
• Music that drives the edit: beats, bars and phrases are detected, and cuts snap to them.
• Sound effects placed on the same timing as the animation.
• Optional: Your agent composes the soundtrack and generates realistic sound effects, on your own machine.

You need macOS or Linux and Node.js 22.12 or newer.

git clone https://github.com/saeedvaziry/caleb-video-editor.git
cd caleb-video-editor
./storyboard setup
./storyboard start

Setup walks you through the rest (ffmpeg, your Claude Code or Codex login, and whether you want music and sound-effect generation) and installs everything inside this folder. Run it again any time to change your choices. It installs packages with npm ci --ignore-scripts, so no package's install script ever runs: don't use npm install here.

Install a current Codex CLI (0.159.0 or newer recommended) and run codex login. Choose Codex in setup or in the chat's agent selector; Claude Code is not required. The model selector reads the models and reasoning levels in Codex's local catalog, with Codex default available even before the catalog is populated.

For non-interactive setup: ./storyboard setup --yes --provider=codex. To override the default at startup: STORYBOARD_PROVIDER=codex ./storyboard start. Both agents remain available in the editor when installed.

./storyboard setup --yes --host=0.0.0.0 --port=5299 saves the bind address and port (--ip also works). Then run ./storyboard start, or ./storyboard restart app if it is already running. Open http://<server-LAN-IP>:5299 from another device. The default remains localhost only.

Network access has no login: anyone who can reach the port can edit projects and use your agents. Use a trusted network/firewall, never the public internet. See configuration.
