AI-generated video that's way too good

She pushes buttons on a jukebox and you can see the fingers exerting force. * Ankle musculature is right. * Dancing with a partner looks right. * Fingers running along a doorframe have proper stick-slip. * Standing on a padded seat shows the upholstery bending properly.
