Researchers have analyzed whether video foundation models encode intuitive physics knowledge within their representations. Using frozen-feature probing on benchmarks like IntPhys2 and Minimal Video Pairs (MVP), they compared models such as V-JEPA, VideoMAE, and LTX-Video. The study found that V-JEPA performed best, particularly with probes focusing on temporal dynamics, indicating that intuitive physics knowledge emerges in these models but its accessibility varies with pretraining methods and model depth.
