Having worked in the industry, I've seen UltraHD with a proper setup. (with the 192 channel sound)

for documentaries and sports, yeah, its brilliant.

But for "film"? it sucks.

why?

Because it looks like a play, but with bad acting. Everything that we have learnt, subconsciously, about film, is based on 24 FPS. Any action of any narrative substance in a modern film is linked to a slowmo. This relies on 24FPS. Because things are smooth, we register it as different.

Now, I suspect where High framerate will be a thing is in VR. But thats a new medium, in the same way the talkies were.

Watch a bunch of 60fps movies and I assure you that you will look back at 24fps movies and think those look weird.

... I have, I do, I see lots of them.

ultraHD is 8k @ 60fps.

its great for sports and nature documentaries. films look like plays. actors look stilted and wooden.
