Inference-time 'Reasoning Guidance' can be derived by converting MMGR's logical constraints into differentiable energy functions, significantly improving physical consistency in video generation without retraining.

Feasibility: 8 Novelty: 7

Motivation

Current video generation models optimize for perceptual quality (FVD) rather than logical consistency, often hallucinating physically impossible transitions. While MMGR evaluates these failures, it doesn't solve them; using the benchmark's constraints as an active guidance signal during the diffusion reverse process could bridge the gap between visual fidelity and reasoning.

Proposed Method

Develop a set of differentiable logic functions corresponding to MMGR's categories (e.g., object permanence, gravity). During the sampling phase of a latent diffusion video model, calculate the gradient of the generated latent regarding these logic functions (similar to classifier-free guidance). Update the latent vector at each denoising step to minimize the 'reasoning error' while maintaining the original text-condition.

Expected Contribution

A plug-and-play inference method that boosts MMGR scores for existing models (like Sora or Stable Video Diffusion) and demonstrates that reasoning can be imposed as a constraint rather than just learned from data.

Required Resources

Access to weights of a state-of-the-art open-source video model (e.g., SVD or AnimateDiff), high-end GPU cluster for inference experimentation, and the MMGR dataset definitions.
