RankVideo

RankVideo is a video-native reasoning reranker for text-to-video retrieval, fine-tuned from Qwen3-VL-8B-Instruct.

The model explicitly reasons over query-video pairs using video content to assess relevance. It was introduced in the paper RANKVIDEO: Reasoning Reranking for Text-to-Video Retrieval.

Training Data

This model was trained using the MultiVENT 2.0 dataset.

Usage

You can use the model for scoring query-video pairs via the rankvideo library as follows:

from rankvideo import VLMReranker

reranker = VLMReranker(model_path="hltcoe/RankVideo")

# Score query-video pairs for relevance
scores = reranker.score_batch(
    queries=["person playing guitar"],
    video_paths=["/path/to/video.mp4"],
)

print(f"Relevance score: {scores[0]['logit_delta_yes_minus_no']:.3f}")
