Changing aspect ration in iMovie from 16:9 to 9:16
Hello. I have recently used the iMovie 10.1.9 version for making a short video for my IGTV channel. I am trying to change the aspect ratio of the movie from 16:9 to 4:5 or 9:16 (which is the IGTV specification). But I am unable to do it or know how to do it. Can someone let me know how best I can work through this.
I did read a few blogs where it said to navigate from "File" to "Project Properties" where the aspect ratio can be edited. I did try to look for the "Project Properties" but I am unable to find that under my file menu as well.
