Motion Fluidity Optimization

via “motion smoothness and optical flow quality assessment”

16-dimension benchmark for video generation quality.

Unique: Dedicates a specific evaluation dimension to motion smoothness and optical flow quality rather than bundling motion assessment into general temporal stability or perceptual quality metrics. Evaluates motion across diverse prompt categories to capture smoothness across different motion types and speeds.

vs others: Provides motion-specific evaluation separate from flickering or subject consistency, enabling developers to optimize motion naturalness independently from other temporal quality dimensions, rather than using aggregate metrics that conflate motion with other factors.
