Hey Product Hunt! 👋Most FFmpeg utilities are designed as standalone web tools, but we noticed developers frequently need to provide video timeline configurations inside their own custom web dashboards, CMS platforms, or internal applications.We built FFmpegLab to be the ultimate free, embeddable video timeline component for FFmpeg. Instead of writing complex canvas or rendering pipelines from scratch, you can drop FFmpegLab right into your app.Because collaborative script editing shouldn't mean slow loading screens, we engineered it around a local-first architecture. We integrated Evolu CRDT sync with SQLite on the frontend for instant, offline-capable multiplayer collaboration and Supabase on the backend for robust data preservation and auth. Teams can edit project layers simultaneously and leave nested, frame-accurate comments without ever waiting on a server response. When the edit is done, it outputs production-ready terminal strings.You can test the collaborative features right now—we have a live multiplayer demo running directly on ffmpeglab.com! Open it in two browser windows or share the link with a teammate to see the real-time syncing and threaded comments in action.We're keeping this completely free and open source. Check out the demo and let us know what kind of applications you plan to embed it into! 👇
