🌟 We released LVBench, a new benchmark for long video understanding!
👀 Introduce to LVBench
LVBench is a benchmark designed to evaluate the capabilities of models in understanding long videos. We collected extensive long video data from public sources, annotated through a mix of manual effort and model assistance. Our benchmark provides a robust foundation for testing models on extended temporal contexts, ensuring high-quality assessment through meticulous human annotation and multi-stage quality control.
Features
- Core Capabilities: Six core capabilities for long video understanding, enabling the creation of complex and challenging questions for comprehensive model evaluation.
- Diverse Data: A diverse range of long video data, averaging five times longer than the longest existing datasets, covering various categories.
- High-Quality Annotations: Reliable benchmark with meticulous human annotation and multi-stage quality control processes.

Our dataset is under the CC-BY-NC-SA-4.0 license.
LVBench is only used for academic research. Commercial use in any form is prohibited. We do not own the copyright of any raw video files.
If there is any infringement in LVBench, please contact shiyu.huang@aminer.cn or directly raise an issue, and we will remove it immediately.
Download
Install video2dataset first:
pip install video2dataset
pip uninstall transformer-engine
Then you should download video_info.meta.jsonl
from Huggingface and
put it in the data
directory.
Each entry in the video_info.meta.jsonl
file has a key field corresponding to a YouTube video's ID. Users can download
the corresponding video using this ID. Alternatively, users can use the download script we provide, download.sh, for
downloading:
cd scripts
bash download.sh
After the execution, the video files will be stored in the script/videos
directory.
Install LVBench
pip install -e .
Get Evaluation Results and Submit to Leaderboard
(Note: if you want to try the evaluation quickly, you can use the scripts/construct_random_answers.py
to prepare a
random answer file.)
cd scripts
python test_acc.py
After the execution, you will get an evaluation results file result.json
in the scripts
directory. You can submit the
results to the leaderboard.
