You are correct! UHD is still 1080p for subtitles, so maybe the urgency isn’t really there. Faithwyn did discover what must be a bug in Cyberlink PowerDVD 16 with 1080p subs on 4K video though.

So maybe 4K subs aren’t actually needed at all (it is just text after all). Nevertheless it’ll be nice to have the capability, should there be a need. I’m thinking there may actually be a use for some of the 35mm theatrical alien subs in native 4K (I’m in the process of grabbing some new ones from 4K77 now). Not so sure about the others except to have them in the Super Awesomest High Resolution for MKV’s. Cause they really do look pretty sharp, when your eyeball is right up against the screen.

But I’ve also been sitting on changes to this project for going on two years, and the changes are certainly significant enough to warrant a release. So a newer version is well overdue, even if the 4K business isn’t really a thing.
