🚀🚀🚀 Official implementation of ShareGPT4Video: Improving Video Understanding and Generation with Better Captions.

Here is a video for introducing ShareGPT4Video clearly:

• Authors: Lin Chen*, Xilin Wei* Jinsong Li*, Xiaoyi Dong, Pan Zhang, Yuhang Zang, Zehui Chen, Haodong Duan, Bin Lin, Zhenyu Tang, Li Yuan, Yu Qiao, Dahua Lin, Feng Zhao📧, Jiaqi Wang 📧
• Institutes: University of Science and Technology of China; The Chinese University of Hong Kong; Peking University; Shanghai AI Laboratory
• Resources: [Paper] [Project Page] [ShareGPT4Video Dataset] [Colab]
• Models: [🤗ShareGPT4Video-8B] [🤗ShareCaptioner-Video]
• Demo: [🤗ShareGPT4Video-8B] [🤗ShareCaptioner-Video]

• 🔥 A large-scale highly descriptive video-text dataset, 40K GPT4-Vision-generated video captions, around 400K implicit video split captions.
• 🔥 A general video captioner for various video durations, resolutions, and aspect ratios, approaching GPT4-Vision's caption capability, featuring two inference modes targeted for quality and efficiency, separately.
• 🔥 A superior large video-language model ShareGPT4Video-8B, lasting 5 hours on 8xA100 GPUs of training respectively.
• 🔥 Improving Text-to-Video performance with high-quality video captions generated by our ShareCaptioner-Video. Thanks to Open-Sora-Plan.

You can directly use our ShareGPT4Video model for conversation with your own video by the following command:

python run.py --model-path Lin-Chen/sharegpt4video-8b --video examples/yoga.mp4 --query Describe this video in detail.

Or you can build your local demo to enjoy our ShareGPT4Video-8B with the following command:

python app.py

You can build your local demo for enjoying our ShareCaptioner-Video with the following command:

cd captioner

python app.py

git clone https://github.com/ShareGPT4Omni/ShareGPT4Video
conda create -n share4video python=3.10 -y
conda activate share4video

cd ShareGPT4Video
pip install --upgrade pip
pip install -e .
pip install -e ".[train]"
pip install flash-attn --no-build-isolation

To validate the effectiveness of high-quality video captions for helping to improve the LVLMs' comprehension capabilities. We choose the VideoLLaVA and LLaMA-VID models as our baselines. The SFT data used for both models is LLaVA-mix665K image data plus VideoChatGPT-100K video data. We replace 28K caption data in VideoChatGPT-100K with 28K high quality caption data from ShareGPT4Video. Next, we take VideoLLaVA as the example.

You need to follow the instructions in VideoLLaVA to prepare the images and videos first, then download the 28K videos used in ShareGPT4Video from HuggingFace (only involves bdd100k, ego4d, and panda).

Finally, you can specify the llava_v1_5_mix665k_with_video_chatgpt72k_share4video28k.json file in the finetune.sh to perform the SFT to reproduce the results in the paper.
