FAQ
- Is my media uploaded?
- Not to app servers by default. FFmpeg.wasm tools transcode in the browser; the wasm core is fetched from CDN first time.
- Large files?
- Browser memory limits apply. Test with short clips first.
- Why first run is slow?
- FFmpeg core download. It can be cached afterwards.
