I detailed this in another post and saved it, I'll copy and paste so as to avoid breaking any rules about linking. Before I go on, I'll mention that some of that "uncanney valley", that unnatural feeling is not always present or at least not as bad. I'm not big on the technical side of filming or cameras, but I imagine there are a lot of intricacies involved that can be toyed with or tweaked to alleviate some of the worst of it. As well as just plain differences in cameras, same way some computer components will handle things differently.
Anyhow, here's the long version about FPS in film and how our brains work in general:
As far as film goes.
60fps + high resolution can create a situation where the information being beamed at you is hyper realistic and it runs into that same place in our perception that some 3d stuff does, that "uncanny valley."
In real every day life, we're fed a constant stream that is unlimited, yet we fail to process a lot of of it. When it's pushed at us in film, it can be jarring, too much in focus(or out), too much contrast, too much definition of everything. Because of this, some 60FPS playback almost looks as if it is in fast forward just a smidge. (some TV shows, Benny Hill specifically, would do such things frequently, raise playback speed just a tiny bit for a bit of comedic effect)
For example. A slow motion shot of someone getting punched, you see the shockwave travel through the cheeks and it looks all weird and distorted because we do not catch all that detail in real life. 60fps or more is like that, you're just playing it back faster and it forces us to see some of that, what we would otherwise just fail to see.
You've taken out some of that motion blur that is the closest approximation to what our brains are doing when they disregard information, and replaced it with detailed information.
What we've done is stepped up from flickering(~15fps) into ~30 interpolated, and then stepped beyond that to true 60. ~30 was the ideal middleground or hybrid that simulated how the brain prioritizes information and we're now experiencing the opposite effect of flickering, which is hyper realism, seeing too much, more than what our brains typically handle.
We can perceive isolated events at over 30, even over 60, by some estimates over even 200, but for everything to be captured and replayed at 200 would make a great many people not feel well.
On motion blur
At 30 fps capture, you will get motion blur very akin to how our minds deal with rapid movements. This is information we either disregard or cannot process fast enough, because of exposure time of the capture device, it is captured much in the same way that the human visual system would perceive it(more data in a longer time frame) and comes across as more "normal" to more people.
That is why motion blur in video games often looks like ass. Because it is based on an algorithm, it is merely another approximation, a trick, and our brains do not like being tricked. It's like fake cheese substitute on that school pizza that you hate. It can be close, but it's never quite right.
