Wasn’t normal 35mm film about the equivalent of somewhere between 4k and 8k depending on the film stock?
Plus, the projector optics will always limit the sharpness of the picture. No lense is ideal, and even ideal lenses would have fundamental limitations due to diffraction.
As far as lens optics, we’re really splitting hairs here. 70mm through a quality lens in an imax theater is going to look absolutely fantastic and stunning. Digital is just more convenient and at some point it will catch up and surpass film.
My point was more like that even IMAX film doesn’t quite get to 18k equivalent, more like 12 to 16k. Honestly, anything above 4k (for normal widescreen content) even on big screens is barely noticeable if noticeable at all. THX recommends that the screen should cover 40° of your FOV; IMAX is what, 70°, so 8k for it is already good enough. Extra resolution is not useful if human eye can’t tell the difference; it just gets to the meaningless bragging rights territory like 192 kHz audio and DAC-s with 140 dB+ S/N ratio. Contrast, black levels, shadow details, color accuracy are IMO more important than raw resolution at which modern 8k cameras are good enough and 16k digital cameras will be more than plenty.
Yup that’s why people can go back and rescan old film movies to make them into 4k now that we have better cameras, but you can’t do that with movies that were recorded with digital
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.
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.
The screens aren’t the problem. It’s often the hardware driving it. The current top generation of gaming gpus struggles at 8k. There’s very little chance of being able to render and play 16/18k
You are in fact wrong lol. Actual film has a resolution equivalent of something like 18K.

Something like that.

Speaking of projectors, don’t they max at something like 100 nits?

Storing it isn’t the problem, you’ll still need to be able to record and project at that resolution.

Rendering video and rendering games are pretty different. Video is generally easier especially once it’s mixed down.
It is technically possible but you’re right it would be absurdly expensive.
Not enough to justify using such a proprietary technology
Not like the off the shelf stuff you can get to store and show 18K.
