iMovie is a built-in video editing tool on iOS and MacOS. It doesn't have a Windows version. If you want to use iMovie to change the aspect ratio on a desktop, make sure you have a Mac.
iMovie 10 or later version can only export your videos in the aspect ratio of 16:9 by default. To adjust the aspect ratio, you need to crop your video. Here is how you can change the aspect ratio in iMovie on Mac.
Open the iMovie and upload the video that you want to change the aspect ratio of.
Head to the top and click on the Crop icon. Next, adjust the cropping frame to decide the aspect ratio manually.
Click on the blue Check mark button on the top right corner of iMovie.
For Mac users, iMovie is a convenient tool to change the aspect ratio. However, it can only be set by manually cropping the video. In other words, you can only set a general aspect ratio in iMovie. If you want a standard aspect ratio like 9:16, iMovie on Mac couldn't help you with that.
