Good luck editing 8K60p, even if your editor can do it. Personally I’m more interested in what a sensor like this and the accompanying electronics, brings to the table in terms of downsampling to 4K. Just as HD benefits from being downsampled from 4K, we will hopefully see quality gains in 8K>4K.
Shooting in 8K will require some hefty SD cards and data rate requirements, assuming that Sony would continue to use SD cards.
It would be quite an accomplishment for Sony to have not only conquered the 4K60p issue, but to have also done that with 8K60p and not encounter overheating.
For me, the larger question with 8K for this audience, is do we really need 8K? Many people can’t see the difference between quality HD and 4K at typical viewing distances. Having been to many high end video display shootouts, I’ve seen this phenomenon at work. As we move up the ‘law of diminishing returns’ curve, the ability to now see the differences between 4K and 8K will be even less. That’s simply the nature of human visual acuity. To benefit from 8K, you’ll need a huge screen and closer seating distances. Both of these become very difficult to achieve in the typical home.
Personally I found the difference in going from an LCD to an OLED screen, with its perfect blacks, more exciting. To me, perfect blacks have a greater impact on the overall viewing experience than nudging up in resolution. Don’t get me wrong, I love 4K and I can see the resolution advantage, but there are other PQ aspects that can be just as important, if not more so.
A couple of years ago I saw an 8K demo in Vegas. It was fascinating to watch crowds of people walk right past the 85” 8K screen (I think that was the size, it might have been a bit larger) and not even notice! I did the same thing and I was actually looking for the demo! When I turned back and finally noticed it, I like many others, was not overly impressed. I literally put my nose 1” from the screen, looking for the added detail. Yes, at very close proximity it was interesting to see the additional detail and absence of any observable pixel structure, but once you backed up to about 2-4’, it looked like an ordinary 4K screen. I stood there for about 15 minutes after I viewed, just to see other attendee’s reaction. There were many ‘shrugs’ of the shoulders, no exaggeration.
So yes, NHK has begun 8K broadcasts just as they led with 4K, but it’s quite a hassle for them to do so and they’re alone in this project. Here in the US, years after 4K’s introduction, we still have 4K only available from streaming sources (Netflix, Amazon etc) and BluRay. Broadcast? Nope, not a single broadcaster has pulled the trigger. Directv has some 4K content on 3 proprietary channels, but most of this content is repeated endlessly.
The infrastructure costs are considerable as is the bandwidth and that’s why 4K movement among broadcasters is almost non-existent. Now 8K? Okeedokey.
