AI video generation that makes motion follow basic rules of the real world.
It is like a movie stunt coach watching every scene. The skateboard lands on the ramp. It does not float off like a balloon.
It makes moving objects look more real. You may see it in animation, ads, and robot training.
Diffusion
Physics rules can guide Diffusion to make smoother video.
World model
A World model predicts how objects may change or move.
Video-Action Model
Physics rules make action-driven video look more real.
