The next step forward will be a smaller improvement still and so on as we inch interminably towards perfection.
I doubt I'll bother with whatever comes after Bluray...
Does black and white standard definition video from old TV shows work still to tell stories? yes. Does it look great on a 60" HDTV or projected to 100" ? No.
TOS still works on DVD on a 13" color TV. The stories still hold you. The transition to high definition as a standard has taken time.
The idea of 4k UHDTVs starts at 60" really. The idea of 8k UHDTVs are wall-sized like in Back to the Future II
. With that much resolution it's not just about being able to get close but about how big you can make your screen display without necessarily using a projected light image onto a screen from across a room.
Things like UHD takes alot of time to get a consensus on between all the tech companies. It takes even longer for adoption.
This thread deals with how producers (not the TV buying public now or in 5 years) will plan for shooting the next Trek TV series in a 2-10 years so as to not have major issues in 20-50 years with acceptance and the most milking of their Trek franchise cash cow. Yes 4k probably will take 15 years and never fully catch on. The idea is futureproofing a franchise so a TNG-R project never has to happen with the next TV series being shot.
ENT season 4 is locked into 1080p as the resolution. Down the road this might
hurt TPTB from doing a ENT-R to 4k/8k project as only seasons 1-3 were shot on 35mm film. While the series is not the most liked it was at least framed for 16:9 ratio and season 3 looked damn good for a 2003-2004 scifi TV series.
