It is arguable, if scanning and remastering a video could be called creative work.

If a judge decides that putting days to work as creative work, the specific version could be qualify as copyrighted, while the movie itself is not, so everyone could still share the old not copyrighted masters.

I think I read somewhere that companies who have a license to release a movie, still needs specific video master licenses, if they don’t want to make their own.

We could make a test: you upload it, share it, and then we call criterion, and see what happens… 😄 (just a joke)
