4K - the future?

Bigger numbers are always the future, that's what the marketing men would like us to believe anyway.
 
I've only watched the first few minutes of this but whilst they are rightly downplaying the importance of increased resolution by itself they are talking as if Rec 709 is some sort of showstopper for increased dynamic range and gamut. It isn't--Rec 2020 has been agreed and implementations are being worked on.

But AFAIK it's not a proprietary system like Dolby which they are reaching for as the answer, so maybe that's why they haven't heard of it. :)

Indeed, there are a number of proposed solutions being investigated.
 
But why are proprietary ones the ones that get pushed forward?

I'm still not sure why there are proprietary soundtracks (DTS-MA, Dolby TrueHD) on blu rays when uncompressed PCM is available, and by definition at least as good.

Apart from commerce.
 
I don't think the future for 4K technology is short. 4K has x4 times the resolution compared to High Definition and shifting 4K video at 60hz is immense, shifting that massive amount of video data through current gfx cards is pushing the limits of current technology. Even if they made an 8K resolution monitor at 60hz I would bet that the modern computer/gfx card wouldn't be able to handle such huge amounts of data, not for quite a long, long, long while. At a guess you are looking at least between 5 to 10+ years for 8K monitors AND computers that could technically support it.

By computers supporting 8K I am talking about mainstream consumer computers. High end workstations possibly could, but if you were processing 8K raw uncompressed lossless video then you would probably have to use a huge RAM disk as a SATA III drive would simply not be able to keep up with the huge bitrate of uncompressed 8K video stream at 60hz.

Quite a few films these days are shot of RED cameras, as far as I am aware the highest resolution supported by the RED cameras is 6K (Red Dragon), which isn't out yet. As far as I am aware there aren't any commercial cameras that shoot 8K resolution. Even if you could have a camera that could shoot at 8K it doesn't follow that you would get the extra detail vs 4K or 6K as the quality of the glass in the lenses at that high resolution would become a limiting factor in image quality. Chances are that 4K will become the defacto standard for quite a long time.
 
The Red is a 6k Bayer sensor. So approx. 4k actual resolution.
