If you’ve recorded a video in the wrong orientation, you can use Gallery app on your Samsung Galaxy S10 to correct it.

This can be helpful if you start shooting a video in one orientation and then rotate the camera while shooting the video – the Camera app won’t rotate the video while you’re recording, so you’ll end up with most of the video in the wrong orientation.

And occasionally, your phone simply won’t change its orientation when you rotate it. If you don’t notice that the controls are sideways, you’ll capture a video that is oriented incorrectly.

In either case, rotating a video after the fact is easy to do in a native app for Galaxy phones.

Unfortunately, if you shot a video in the wrong orientation intentionally - if you held the phone vertically and shot the video in portrait mode, for instance - rotating the video will simply make it appear sideways. The only way to fix this is to edit the video in a photo editing program on a computer, and manually change its aspect ratio from portrait to landscape (or vice-versa).

4. If the orientation of the video changes during recording, press the play button and let the video run until you reach the part that's rotated, so you can be sure you're properly correcting the rotation.

5. Tap the Rotate button to the right of the video timeline. Depending on the orientation of the video, you may need to tap it between one and three times.
