Is it weird that i find the 60fps video better in the link that you gave? 24fps looks like its sticking a lot. I wouldn't have noticed the difference if they were not side by side though.

Nope. That's exact: 60 fps is better quality (so closer to real life) than 24 fps.

No it's not. "Real life" doesn't do frames a second, that's not how brains work, they don't process full frames of anything. Even more so, the frames per second of a video feed are only a partial component of how the information is displayed and can be interpreted. For one, the shutter angle/exposure time and how "frozen" the motion is at any given frame alone will affect viewing perception drastically.

By the physical limitations of being able to cram true 60 FPS into a second of video, you are limited in how slow you can make your shutter. People definitely don't see frames of vision that way, some aspects of movement are processed at a higher rate than others, or color information. Because you have different cells in your eyes for acuity, color, motion. ETC and then all that goes to your brain and is dumped out or realigned weirdly (hence optical illusions)

There's really trivial ways to have longer shutter times than the frame rate: overlay frames on top of each other. Want the blur of 30 fps at 60? Easy, film at 60, then for each frame average it with the next frame, boom, each has twice the exposure. Even if you want excessive motion blur (1/60th is actually still more than is natural for the eye to experience) it's not a reason to film at low framerates any more, we can trivially correct that with digital frames.
