I think one of the reasons why generated video often feels "off" is a kind of agnosticism about momentum and gravity.

When generating frames the algorithms are indifferent to "before" and "after." This is why people move as if in zero G. Everything is smooth and continuous, but the direction of motion and things like acceleration wobble.
An object falling can suddenly rise. Hair moves as if underwater.
Much of physics works identically irregardless of the direction of time. So to AI video.

AI generated video is always differentiable. And of course it's derivative.
