A new research paper investigates whether video diffusion models, like Video Diffusion Transformers (DiTs), internalize physical principles or merely mimic familiar motion patterns. The study found that physical quantities such as kinematic motion and rigid-body dynamics are accurately decodable from the models' internal representations early in the denoising process. This suggests that the models actively construct physical information rather than just reproducing it from input, with the information being localized in on-object tokens and computed globally but stored locally.
