Real rotation
The frames are rotated and re-encoded, rather than just setting a rotation flag that some players ignore, so the result plays correctly in every app.
Frequently asked questions
Is my video uploaded?
No. Processing uses FFmpeg compiled to WebAssembly and runs entirely in your browser. Your files never leave your device.
Why is it slower than desktop software?
Browser processing runs on a single CPU thread without hardware encoders. Short clips finish quickly; for long 4K videos, reducing the resolution to 1080p or 720p speeds things up considerably.
