Personally I just shoot in 4K, and then downscale to 1080. So except for the transcoding everything is exactly like it has always been for me. I have to add that I have edited an interview-ish thing between two people that i didnt shoot, where I got 4K files delivered. I edited that in 4K on a 1080 timeline to be able to punch in on just one face. So that was easier than setting up 3 cameras. Final delivery was still in 1080.
