If your video was on its right you can click to rotate left option 3 times and your movie file should be good to go. No video editing software is needed! To do this, locate the video file in question, right click or control click the video, and select “Rotate Left”. Now there is a great feature built into macOS Mojave that allows you to very quickly rotate a video directly in the Finder. In the previous years you would need to drop this video into a video editing app such as iMovie and it would take a while to edit, export, and save properly. Lo and behold, Apple has a solution for this. Shorten the clip: Drag the edge of the clip toward its center.

To extend a clip, there must be unused portions of the clip available. Do one of the following: Extend the clip: Drag the edge of the clip away from its center.

Now there are also times that I have experienced when someone starts recording video in portrait and flips the phone to landscape while recording has all ready begun. In the iMovie app on your Mac, skim to the beginning or end of a clip in the timeline that you want to extend or shorten. Now don’t get me wrong, I personally believe there is a place for portrait video! If you are sending a video to someone and you know for sure it will only be viewed on a mobile phone, then sure - go for it! If you feel that now or in the future you may ever want to view this video on a television, computer screen, conference room display, etc - shoot the video in landscape. If you don’t do this, you’ll be seeing your video with 2 black bars on both sides of your footage.
