Frequently asked questions
Rotation requires re-encoding the video — every frame needs to be decoded, rotated, and re-encoded. This is CPU-intensive. Stream copy cannot be used because the pixel data itself changes. A 300 MB video may take 2–5 minutes.
Rotating turns the video 90° or 180° around the centre. Flipping mirrors it along an axis — horizontal flip produces a mirror image (left becomes right), vertical flip turns it upside down along the horizontal axis.
Most sideways phone recordings need 90° clockwise. If that produces an upside-down result, try 90° counter-clockwise instead. Some phones embed a rotation metadata flag instead of baking in the rotation — players that respect that flag show the video correctly, but editors that ignore it show it sideways. Re-encoding via this tool bakes the rotation in permanently.
Yes, slightly. Because rotation requires full re-encoding, there is a small quality reduction — the same trade-off as any transcode. At the default H.264 quality settings this tool uses, the difference is not visible to the naked eye on most content.
If the source video has embedded rotation metadata (common with iPhone and Android clips), some players already show it correctly before rotation. Applying an additional 90° rotation in that case will double-rotate the video. Check how the file looks in your target editor before deciding which rotation to apply.
