– How are 4K UHD edits of movies made?

515 views

I’m watching [this](https://youtu.be/7VxNY2WsJn0) official preview of Back To The Future 3 in 4k, and while it looks amazing, when you watch it on a 4k UHD device, something seems off with the characters, as if they were greenscreened onto another edit of the film or something. I used to imagine they were done with the original prints on film, but it looks too digitial.

They’re re-captures from the original analog films, but using substantially higher resolution capture modern equipment. Not sure if the UHD implies some other process being ran on the capture, but i wouldn’t be surprised. There are interesting techniques for improving fidelity of capture (some of it even uses neural nets), and i wouldn’t be surprised if some of those post-production edits make it seem unnatural.
