metric

VQeval composite long-video quality metric.

The upstream implementation exposes six evaluators that share CLIP, DINOv2, pyiqa, and optical-flow state. Registering one FastVideo metric preserves that sharing and returns the individual dimension results under details.

Classes

fastvideo.eval.metrics.vqeval.metric.VQevalCompositeMetric 

VQevalCompositeMetric()

Bases: BaseMetric

Run VQeval's active dimensions and return its weighted composite.

sample["fps"] is required because VQeval samples long videos based on duration and frame rate. sample["text_prompt"] is optional; when it is absent, VQeval omits text alignment and redistributes its weight exactly as the upstream pipeline does.
