I was using lossless compressed image sizes becuase they were relatively easy to find. So those 4K 16-bit frames were more like 12 MB instead of 50. That's where the compression comes from. Lossless image compression details were much easier to find than losses video compression details, and I could test them myself easily. The 12 MB will depend on the original image, as some compress much more readily than others, but it's reasonable.
As I said I'm sure we could make screens that could do that. They would be absurdly expensive and heavy and stupid, but it could be done. Not worth it though.
And it looks like at least 16k cameras have been made.
So more like 20TBs. And again, that's lossleslly compressing the individual images, but not the video. The video is still uncompressed. Lossless video compression would significantly reduce that.
It is a huge file, but it's just as tractable as that film.
I don't think there's any reason we couldn't make a store 18k video.
And we could make screen at much higher resolutions that that at imax size, or even quite a bit smaller, though I suspect it would be absurdly expensive.
Some people do like the distortion that analog audio provides, that's true. But it is because of something that wasn't in the original audio. It's an artistic choice.
Well, the problem is that we see so many other people fall for propaganda we recognize as ridiculous.
