Weave is a React app that provides a multi-track timeline editor to perform basic video edits like trimming, stitching, transitions, audio tracks etc. which maps directly to an FFmpeg command to render the video.I tried my best to have the React "video" preview closely replicate the FFmpeg lavfi filtergraph output, but naturally this is not perfect (especially replicating the `eq` filter using SVG filters is quite inaccurate).I've built this as a prototype for another project I'm working on, so I don't plan to actively maintain it, but I thought it'd be cool to share it.Try it live: https://weave.salviano.xyz/

Could you build this?
Partial A multi-track React timeline UI is within reach of AI assistance, but mapping an interactive canvas preview accurately to FFmpeg filtergraphs (lavfi) with frame-perfect synchronization requires deep media processing expertise.
What it would actually take: Built with React/TypeScript on the front end, using Web Audio API and HTML Canvas/WebCodecs for playback previews. The core challenge is writing a deterministic compiler that translates timeline operations (cuts, transitions, audio mixing) into complex FFmpeg filter graphs (`complex_filter`) executed via FFmpeg WebAssembly (Wasm) or a headless FFmpeg backend while keeping real-time preview synchronized.
