Reframe runs FFmpeg compiled to WebAssembly
(FFmpeg.wasm) in a Web Worker, so your video
is processed on your own device and the page stays responsive. When the site is
cross-origin isolated (the Cross-Origin-Opener-Policy and
Cross-Origin-Embedder-Policy headers), browsers allow SharedArrayBuffer and
Reframe uses the faster multi-threaded FFmpeg; otherwise it falls back to the
single-threaded build. The details are in docs/ARCHITECTURE.md.
You need Bun 1.x and Node.js 20.9 or newer.

Your videos never leave your device. Reframe collects anonymous performance and error data to improve export reliability; you can opt out in Settings. Exactly what is sent, and what never is, is listed on the privacy page and in docs/DATADOG.md.
