An open-source, layer-based desktop video editor with cut editing, keyframe animation, audio mixing, Whisper-based auto captions, chromakey, and FFmpeg rendering. It exposes its live timeline over MCP so Claude Code can cut from a transcript, add subtitles, or restage clips, landing in the app's own undo history. Installs as a Claude Code plugin.

About Editing
Tools that work on footage you already have: cutting, captions, B-roll, silence removal and recaps, often driving FFmpeg or an NLE.
