DVD-Bench

A benchmark for Dialogue-centric Video Description, evaluating "When, Who, and What is Said" in dialogue-centric videos.

Repository layout

DVD-Bench/
├── data/
│   └── en/
│       └── test.parquet       # English test split annotations
└── videos/

Annotation schema

Each row in data/en/test.parquet contains:

field	type	description
video	string	Video filename, e.g. e-mNCJPxQvQ.mp4. The actual file is at videos/en/<video> in this repo.
character	list<string>	List of character descriptions appearing in the video.
dialogue	list<struct{speaker: string, content: string, time: list<string>}>	Ordered list of utterances; time = [start, end] in MM:SS.

Quickstart

from datasets import load_dataset

ds = load_dataset("tsinghua-ee/DVD-Bench", name="en", split="test")
print(ds[0])

# To get the actual video file, download it from videos/en/<video>:
from huggingface_hub import hf_hub_download
video_path = hf_hub_download(
    repo_id="tsinghua-ee/DVD-Bench",
    repo_type="dataset",
    filename=f"videos/en/{ds[0]['video']}",
)
