movies and games are not the same thing
movies are prerendered and everything is set up and is displayed exactly how the creators wanted you to see it
games are interactive and give the player the ability to control what's going on and are rendered live. having a lower framerate on a game means that control is less responsive and it 'feels' different to the player
but this isn't a game
it's a video
there's no responsiveness here (also, I can play a game on 24fps, but that's probably because I'm forced to with my computoaster), it looks the same
I just played the video through with 480p and then 720p and then back, they look exactly the same.
