Turn the video left, right or upside down, check the result, and create the corrected video.
Phones record orientation as a flag in the file, and plenty of software ignores it — which is how a video that looked upright in your camera roll ends up sideways on a laptop or after an upload. Rotating here turns the picture 90° left, 90° right or a full 180° and bakes the result into the pixels, so it looks correct in every player.
A phone camera sensor has a fixed orientation. When you hold the phone differently, the recording still stores the sensor’s view plus a rotation flag saying how to display it. Apps that honour the flag show the video upright; apps that don’t show it on its side. Rotating with this tool re-encodes the frames in their corrected orientation and writes a neutral flag, which removes the disagreement instead of relying on the next app to read the metadata properly.
If the top of your subject points left, rotate 90° right; if it points right, rotate 90° left; if everything is upside down, use 180°. Note that a 90° rotation swaps the width and height — 1920×1080 becomes 1080×1920 — so a rotated widescreen clip becomes vertical and vice versa. Check the preview before exporting, and if the result is upright but mirrored, the problem is a flip rather than a rotation.
Your phone honours the rotation flag stored in the file and the other program ignores it. Rotating here bakes the correct orientation into the frames, so both show it the same way.
A 90° rotation swaps width and height, so a 1920×1080 clip becomes 1080×1920. A 180° rotation keeps the same dimensions.
This tool handles quarter turns only, because they need no interpolation and lose nothing. Arbitrary angles would require rotating the pixel grid and cropping or padding the corners.
No. That is a mirrored image, typically from a front-facing camera, and the flip tool corrects it. Rotation alone cannot undo a mirror.
Quarter turns move pixels without resampling them, so the only loss comes from re-encoding the file. At a high quality setting the difference is not visible.
