Researchers have introduced SNF-Bench, a new evaluation framework designed to better assess long-horizon video generation, particularly for fixed-camera nature scenes. Traditional metrics often conflate desirable motion (like water or fire) with undesirable background drift, leading to ambiguous scoring. SNF-Bench addresses this by separating static fidelity, flow persistence, and drift leakage, providing a more nuanced understanding of video generation quality. Initial audits using SNF-Bench on publicly available models revealed that metrics rewarding background drift can lead to different model rankings compared to those that strictly measure motion and temporal consistency.
