Before I even start let me say that I know the suggestion is to put 4k into it own library…
99% of my movies are 1080p and that is my preference for space and quality balance. However, there are a few choice movies that I’ll want a 4k version of. I would rather my users get defaulted to the highest non-4k version but then have the option to select a different version if they were savy enough to do that.
Feels like it shouldn’t be a terribly complicated feature. Have a “include x quality in default version selection”. Or hell for my random case use if I could just manually reorder them I’d be happy.
if you have multiple versions of a film (1080, 4K) when playing, your client should present a picker. if you can’t trust your users to choose the version you wish them to, put one into a library only available to them and the other into a library only available to you.
I wish the choices were more granular, but, currently, they’e not.
