Film making at 24fps (while originally selected for pragmatic reasons having to do with film cost and sound fidelity) turned out to be a happy accident. It produces an Impressionistic Effect entirely similar to a money painting. 24fps is absolutely not reality. Our brains know it too. The same way they know that those giant brush strokes in a Van Gough painting are also NOT REALITY. Turns out our brains like to be toyed with. Art is just always “trying to document precisely what our senses would have experienced if we were there”.
That is just a false premise and one they misunderstands art in general.
