This started happening a few months ago. I'm a novice at best but I didn't do anything different. Now I can't figure out how to fix this. I shoot most of my video on either an iphone 10 or a 12. I've tested with both and get the same results when I upload clips to Premiere Pro. I've attached an image to show you what I'm talking about. Also, when I make a white graphic in photoshop, it imports as grey in premiere. Any ideas?
