im still a little confused. I have an iPad Pro. I know you can edit 4K video in iMovie. However, you can't actually watch it in 4K it appears? I export it to my camera roll, or watch the preview in iMovie and it certainly isn't 4K. Am I doing something wrong, or is it purely just to edit 4K video on and not watch it on. I would love the ability to actually watch 4K video (or 2K) on apps like Videos, and YouTube!
