Sometimes when filming with a mobile phone, I shoot in portrait mode. Portrait mode is Okay for social media posts, but not really cool looking on larger screens.
Recently, when working on a larger home video in Adobe Premiere Pro, I discovered a few scenes shot in portrait mode, but actually where meant to be landscape.
Without further ado, here is how to rotate a video in Adobe Premiere Pro
Upload your clip, from the timeline select clip, and click on the effects control, from there under Motion click Rotate and change to 90 degrees
