iMovie only exporting in 720p
I've been struggling to export a video to 1080p but iMovie will only let me go to 720. I tried the trick of uploading a 1080p clip in the beginning, did all of the steps correctly, and it won't register 1080p clips as 1080p or let me export them. I reset my iMovie, too, deleted all of its preferences and restarted the program/my computer several times. I'm looking for a different trick or some way to get it through my computer's head that I'm putting in 1080p clips!!!
