2024.06.13🌟 We are very proud to launch VideoNIAH, a scalable synthetic method for benchmarking video MLLMs, and VNBench, a comprehensive video synthetic benchmark!
We propose VideoNIAH (Video Needle In A Haystack), a benchmark construction framework through synthetic video generation. VideoNIAH decouples test video content from their query-responses by inserting unrelated image/text 'needles' into original videos. It generates annotations solely from these needles, ensuring diversity in video sources and a variety of query-responses. Additionally, by inserting multiple needles, VideoNIAH rigorously evaluates the temporal understanding capabilities of models.
We utilize VideoNIAH to compile a video benchmark VNBench, including tasks such as retrieval, ordering, and counting. VNBench contains 1350 samples in total. VNBench can efficiently evaluate the fine-grained understanding ability and spatio-temporal modeling ability of a video model, while also supporting the long-context evaluation.
VideoNIAH is a simple yet highly scalable benchmark construction framework, and we believe it will inspire future video benchmark works!
Download the raw videos in VNBench from the google drive link. Download the annotation of VNBench from the huggingface link License:
VNBench is only used for academic research. Commercial use in any form is prohibited.

Prompt:
The common prompt used in our evaluation follows this format:
<QUESTION>
A. <OPTION1>
B. <OPTION2>
C. <OPTION3>
D. <OPTION4>
Answer with the option's letter from the given choices directly.
Evaluation:
We recommend you to save the inference result in the format as example_result.jsonl. Once you have prepared the model responses in this format, please execute our evaluation script eval.py, and you will get the accuracy scores.
python eval.py \
--path $RESULTS_FILEIf you want to use GPT-3.5 for evaluation, please use the script wo provided gpt_judge.py.
python gpt_judge.py \
--input_file $INPUT_FILE \
--output_file $OUTPUT_FILE - Evaluation results of different Video MLLMs. Please visit the leaderboard for more details.
