contents We introduce World Consistency Score (WCS), a novel unified evaluation metric for generative video models that emphasizes internal world consistency of the generated videos. WCS integrates four interpretable sub-components - object permanence, relation stability, causal compliance, and flicker penalty - each measuring a distinct aspect of temporal and physical coherence in a video. These submetrics are combined via a learned weighted formula to produce a single consistency score that aligns with human judgments. We detail the motivation for WCS in the context of existing video evaluation metrics, formalize each submetric and how it is computed with open-source tools (trackers, action recognizers, CLIP embeddings, optical flow), and describe how the weights of the WCS combination are trained using human preference data. We also outline an experimental validation blueprint: using benchmarks like VBench-2.0, EvalCrafter, and LOVE to test WCS's correlation with human evaluations, performing sensitivity analyses, and comparing WCS against established metrics (FVD, CLIPScore, VBench, FVMD). The proposed WCS offers a comprehensive and interpretable framework for evaluating video generation models on their ability to maintain a coherent "world" over time, addressing gaps left by prior metrics focused only on visual fidelity or prompt alignment.
