Frequently asked questions
- No. RuruSpace runs a WebAssembly build of FFmpeg inside your browser tab. The video is read from disk into memory and never touches the network.
- WASM encoding runs roughly 2–5× slower than native FFmpeg. A one-minute 1080p clip typically takes 1–3 minutes depending on your CPU.
- CRF 23 is visually transparent for most content. 28 halves the size again with mild softening; below 18 gains little.
