Every once in a while, we make the mistake of using our iPhone to record video as if we are making a still photograph. We tend to prefer vertical photos and accordingly, don’t always remember to rotate the phone to horizontal for video.
There’s a fix for that and it’s easy.
This works when you accidentally record video in vertical mode or even upside down on your iPhone. To fix that, just open the Photos App.
Find the ALBUMS tab. Scroll all the way down to MEDIA TYPES and choose VIDEOS.
Pick the video you want to rotate and choose EDIT. Then select the CROP ICON on the bottom right. Then you’ll see this ROTATE ICON. Just tap on it until the video is in the format you want and select DONE to finish. It’s that easy.
