Photos on iMovie go black after editing
When I inserted still photos to overlay video on iMovie, the photos showed up fine with the first play-through. However, when I edited the Ken Burns style on the photos, they all just show up as a black screen. I've done this before without this problem. Help, please, I'm working to deadline!
Running Catalina 10.15.7 on iMac and iMovie is 10.2.2
