Research questionHow can we evaluate physical reasoning in video models without reliable motion calibration?Absolute motion measurements in video can be misleading when scene scale, timing, and camera calibration are unknown. This makes it difficult to tell whether a video model has captured physical laws or merely produced plausible-looking motion.

Latest papersRecent research connected to this question, newest first.Principia: Relational Physics Tests for Video ModelsThe source evaluates generated videos using relational consistency between paired objects across eight Newtonian phenomena, with a calibration-independent image-space score. It reports results for six video generators and tests whether vision-language models can detect relational physics violations; the evidence comes from controlled real-world scenes and thousands of generations.research paper · Sep 3, 2026
