Show HN: FableCut – A browser video editor AI agents can drive (zero deps)

FableCut is a browser-based, Premiere-style video editor designed for AI agent control. Its unique feature is exposing the entire timeline as a JSON document, allowing AI agents (like Claude Code) to edit videos by modifying this project file. The UI hot-reloads live, enabling simultaneous human and AI collaboration. It offers extensive editing, visual, motion, and text features, including AI background removal and the ability to remake videos from a reference.
