Weird Video color issue

When I'm in Photos or iMovie viewing movies created on the new iPhone 12 all of my new movies filmed on it have a strange color balance issue that I can seem to remove. If I view the same movies on the iPhone they are all fine. They get distorted when the move from the cloud to my other devices. All the pictures come out fine, but I don't know how to resolve this strange issue. Any ideas. It is a brand new phone and I've only had it for a week or so.

thanks,
