24fps looks a little different on a real film projector than on nearly all home screens, too. There's a little time between each frame when a full-frame black is projected (the light is blocked, that is) as the film advances (else you'd get a horrid and probably nausea-inducing smear as the film moved). This (oddly enough!) has the effect of apparently smoothing motion—though "motion smoothing" settings on e.g. modern TVs don't match that effect, unfortunately, but looks like something else entirely (which one may or may not find intolerably awful).
Some of your fancier, brighter (because you lose some apparent brightness by cutting the light for fractions of a second) home digital projectors can convincingly mimic the effect, but otherwise, you'll never quite get things like 24fps panning judder down to imperceptible levels, like a real film projector can.
Me at every AirBnB: turn on TV "OH MY GOD WTF MY EYES ARE BLEEDING where is the settings button?" go turn off noise reduction, upscaling, motion smoothing.
I think I've seen like one out of a couple dozen where the motion smoothing was already off.
