New method refines video generators using frozen world models

By PulseAugur Editorial · [1 sources] ·

Researchers have developed Off-Manifold Refinement (OMR), a novel inference-time technique designed to improve the physical consistency of video generators. OMR injects feedback from a frozen world model directly into the sampling trajectory of a video generator. This method augments the generator's velocity with the gradient of an adapter-space V-JEPA 2.1 surprise energy, guiding the latent representation towards more physically plausible regions. The approach demonstrated a 5.0 percentage point absolute increase in the joint Semantic-Adherence-and-Physical-Commonsense metric on the VideoPhy-2 dataset, while only slightly increasing runtime compared to other methods.

    Off-Manifold Refinement: Guiding Video Generators with a Frozen World Model

    arXiv:2608.29904v1 Announce Type: new Abstract: Modern video generators routinely fail at physical dynamics: objects float, trajectories violate gravity, contacts vanish. Standard denoising and flow-matching objectives fit visual data distributions but do not explicitly penalize …
