An independent physics-consistency checker, Haga, has identified a failure mode in the CogVideoX-5b-I2V model. When prompted with a "ball and block fall" scenario, the model generated videos where the object remained airborne with minimal motion instead of falling. A pre-registered test using a frozen detector confirmed this "static_hover" failure in 100% of nine held-out clips, while real physics footage remained unaffected. AI
