VChain: Inference-Time Visual Reasoning Improves Video Generation Coherence
ziqi_huang_ · x · 2026-08-14
Video generation models often produce smooth clips but fail at complex dynamics. VChain introduces a chain-of-visual-thought framework that uses multimodal models to reason critical states and generate sparse keyframes, guiding the generator at key moments without retraining. Experiments show significant quality improvement. Author Ziqi Huang presents on Aug 14.
