4K video editing on iPhone glitch & pushing Photos to iCloud

I’m recording daily videos in 4K for a YouTube project on my iPhone…anywhere from 3-10 minutes long.

I crop the video directly after shooting, but frequently when I open the video in iMovie, I get the uncropped version, and I can’t find a pattern with it.

Ideas?

Nobody needs to see my bowl of mixed veggies or Clue Jr. on the table…

Also…had an error message tonight when I was exporting the finished video to Photos from iMovie that there wasn’t enough space on my device to do so (even though I have over 100GB free). Got me to thinking…is there a way (besides “Optimize iPhone Storage” to push all of these videos to iCloud?
