Researchers have analyzed two video foundation models, V-JEPA 2 and VideoMAE-v2, to understand their spatiotemporal representations. The study found that both models effectively encode camera motion and exhibit moderate performance in anomaly detection, but struggle with intuitive physics tasks, indicating limited reasoning about physical principles. Additionally, the research revealed that temporal features within videos form smooth trajectories in the models' representation space, enabling geometry-aware steering for smoother video interpolation.
