Video Rotate

A video recorded with the phone held upright but started while it was flat on a table often comes out sideways. Videos from action cameras mounted upside down need a 180° turn. Screen recordings of a phone may need turning for a landscape presentation. Clips received through messaging apps can lose the rotation flag and appear sideways on a computer even though they looked right on the phone. In each case, one rotation fixes the file permanently, so you never have to rotate it again in a player or editor, and anyone you share it with sees it the right way up.

Look at the preview and pick the turn that makes the picture upright. Turning by 90° swaps width and height, so a landscape video becomes portrait and the other way round.

Many tools rotate a video by only changing a flag in the file that tells players to turn it while playing. That is fast, but some players, editors, websites and older TVs ignore the flag, so the video still appears sideways. This tool re-encodes the frames already turned, so the picture is upright for every app. Re-encoding takes longer than changing a flag, and uses a high quality setting so the difference is not visible.

Front cameras often save a mirror image, so writing on a whiteboard or a T-shirt reads backwards. Turn on Mirror to flip the picture left to right; combine it with a turn if the video is also sideways. Mirroring is also useful for dance and fitness videos, where following a mirrored teacher is easier.

The rotated video is saved as H.264 MP4 at a quality suited to its size, using your device's video encoder. Videos the browser cannot decode, such as some HEVC files from iPhones on Windows without the HEVC extension, are explained with a message. Long videos take a while to process; you can cancel at any time. Nothing is uploaded, so personal recordings stay on your device. To also change the size or remove part of the picture, use the Video Resizer or the Video Cropper.
