Then why have films run at 21fps? o.0

I don't know if you are playing with the other guys or not but in case not, I will come here to ruin everything...

Movies themselves don't 'run' anywhere. The entire idea we have about moving image is false. Truth is that still image after still image is shown to your eyes in rapid flashes, which in your brain then creates the illusion of movement. Exactly the same as if you drew image after image on every page in your notebook and flip through the entire thing. It looks like it is moving. Add sound to the mix and you have the "moving" image.

Movies by default run at 24 (23,97) frames. Then they add motion blur to have smoothness in video. Of course, nowadays we have 30, 60, 120, 240 all the way up to 10,000s of frames per second and it's still growing but movie industry still uses 24 frames by default. Recent years some directors have chosen to do 48 with some movies, like The Hobbit: The Desolation of Smaug (btw, I was laughing my ass off at the theater when I saw the part where they recorded with GoPro!). Basic idea is that the more frames there is the harder it is for your brain to tell when the still image changes from one to another, thus creating "smoother movement".

Personally I am interested what is the maximum framerate and resolution human brain can possibly distinguish or if it's endless. YouTube also has supported 8K since either 2014 or 2015, which is crazy... Very high amounts of hard drive space is needed for that.

Anyway, if someone wants to look deeper then here's a nice 15 minute video:
