• Abstract: Recent advances in diffusion-based video generation have yielded unprecedented quality in visual content and semantic coherence. However, current approaches predominantly rely on statistical learning from vast datasets without explicitly modeling the underlying physics of motion, resulting in subtle yet perceptible non-physical artifacts that diminish the realism of generated videos. This paper introduces a physics-informed frequency domain approach to enhance the physical plausibility of generated videos. We first conduct a systematic analysis of the frequency-domain characteristics of diverse physical motions (translation, rotation, scaling), revealing that each motion type exhibits distinctive and identifiable spectral signatures. Building on this theoretical foundation, we propose two complementary components: (1) a physical motion loss function that quantifies and optimizes the conformity of generated videos to ideal frequency-domain motion patterns, and (2) a frequency domain enhancement module that progressively learns to adjust video features to conform to physical motion constraints while preserving original network functionality through a zero-initialization strategy. Experiments across multiple video diffusion architectures demonstrate that our approach significantly enhances motion quality and physical plausibility without compromising visual quality or semantic alignment. Our frequency-domain physical motion framework generalizes effectively across different video generation architectures, offering a principled approach to incorporating physical constraints into deep learning-based video synthesis pipelines. This work seeks to establish connections between data-driven models and physics-based motion models.
