🚀🚀🚀 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]
• 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.
