A friend is attempting to fix the Funi 30ANIV BluRays of Z, and he’ll prolly hand them off to me to encode. (Which means I’ll prolly do the same voodoo I did with the Levels.)
Might only be worth 480, he suggested (because the processing he’s using to mitigate the filter damage does include some blurring), though his experiments have been at 720.
Honestly I don’t see a point in doing anything with FUNi’s 30th anniversary set since it’s trash through and through. There’s friggin artificial grain added to the footage for christ’s sake presumably to mitigate complaints about the lack of grain which was stupid because it would have been easier to just tone back the DNR and everything wouldn’t have been so bad, something between the grain on the level sets and Kai would be the sweet spot imo (the level sets while fantastic looking had a little too much grain for my tastes, Kai on the other hand has too little grain, it isn’t as bad at the 30th anniversary sets mind you but Kai still went a little bit overboard), add that and the fact that the cropping for the 4:3 framing is complete overkill and it’s a waste of time, even if one could make it look better it’d just be a stop-gap measure at best, you’d be better off working on deinterlacing the DBOX footage (assuming it needs to be deinterlaced) and working from there.
