> Motion-capture works fine because that's real motion
Except in games where they mo-cap at a frame rate less than what it will be rendered at and just interpolate between mo-cap samples, which makes snappy movements turn into smooth movements and motions end up in the uncanny valley.
It's especially noticeable when a character is talking and makes a "P" sound. In a "P", your lips basically "pop" open. But if the motion is smoothed out, it gives the lips the look of making an "mm" sound. The lips of someone saying "post" looks like "most".
At 30 fps, it's unnoticeable. At 144 fps, it's jarring once you see it and can't unsee it.
