Frequently Asked Questions
Are my media files uploaded?
No. Processing uses ffmpeg.wasm in your browser. Files never leave your device. The first run downloads a ~25MB media engine from a CDN.
Why is the first run slow?
The media engine (~25MB) downloads once per browser session from a CDN, then stays cached.
Which formats work?
Most MP4/WebM/MOV and common audio formats your browser and ffmpeg.wasm can decode. Exotic codecs may fail.
