The Pulse of Motion: Measuring Physical Frame Rate from Visual Dynamics

ArXi:2603.14375v1 Announce Type: cross While recent generative video models have achieved remarkable visual realism and are being explored as world models, true physical simulation requires mastering both space and time. Current models can produce visually smooth kinematics, yet they lack a reliable internal motion pulse to ground these motions in a consistent, real-world time scale. This temporal ambiguity stems from the common practice of indiscriminately
