PRIVATE BROWSER PROCESSING
Rotate a video when the camera orientation was wrong, not the moment
A good clip shot sideways is still a good clip. Rotate it 90° clockwise, 90° counter-clockwise or 180° and export a corrected MP4 locally.
Rotate video
Orientation mistakes are boring, which is exactly why the fix should be simple
Rotation re-encodes the video so the corrected orientation is baked into the frames rather than relying only on display metadata that players may interpret differently.
Privacy and limitations
Processing uses FFmpeg WebAssembly locally. The video is not uploaded by this tool. Closing or refreshing the page clears the working file. Speed depends on the browser, device memory, source codec, duration, and resolution, and tools that re-encode are not lossless.
Common questions
Which video formats are supported?
The FFmpeg core handles common formats such as MP4, MOV, WebM, MKV, AVI, MPEG, M4V, 3GP, TS and WMV, though the browser may not preview every format.
Is my video uploaded to DJAI?
No. The source file is read and processed in your browser on your device.
Why can the first run take longer?
The browser downloads an FFmpeg WebAssembly core of roughly 31 MB the first time processing is needed; caching can help later runs.
