Why movies look weird at 48fps, and games are better at 60fps, and the uncanny valley…

Let’s end this debate once and for all. Humans can see frame rates greater than 24fps. Once you’ve accepted that fact, the next question is why do movies at 48fps look “videoy”, and why do movies at 24fps look “dreamy” and “cinematic”. Why are games more realistic at 60Hz than 30Hz?
Unfortunately, you’re also going to get the audience extracting much more detail out of that scene than at 24Hz. Which unfortunately makes it all look fake (because they can see that, well, the set is a set), and it’ll look video-y instead of dreamy – because of the extra motion extraction which can be done when your signal changes at 40Hz and above.
The short version is, to be “cinematic”, you really need to be well under 41Hz, and above the rate where motion becomes jerky – also known as the phi phenomenon or “apparent motion”—which is ~16Hz, so that the motion looks like motion.
Of course, realistically, the proof of the pudding is in the eating.
Some of this post is speculation – at least until experiments are performed on this. It may actually be real new science by the end of the day. Smile I’d love to hear from any actual professionals in the field who’ve done research in this area.
