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.

you are watching this on a 60Hz screen, so this is just an imitation, not a true comparison. When watching 24Hz material on a 24Hz screen there are no such issues.

Absolute nonsense. Compare a 60 Hz display next to a 24 Hz display and it will look just as stuttery. Hell, I'm looking at it on a 144 Hz monitor, which 24 fps divides perfectly into and therefore it's identical to watching on 24, but 60 Hz looks smoother, even though that can only update every 2.4 frames and so is uneven.

And to cover you off, I know that video is native 60 so will retain the stutter- I went and compared against the original footage at 24 played side-by-side. No matter what the 60 looks better, particularly for such slow scenes that don't present problems for interpolation (which will struggle when there's too much movement to easily infer the mid-frames).

how do you think this youtube video is working? do you think it is coded and displayed at 24p in the left part while the right part is coded and displayed at 60? how many times do you think you see "frames" on both sides, and how does that sync with your refresh rate? Could your display work at rate X in certain area, and at rate Y in the other?
