# 🦜 VideoChat [[paper](https://arxiv.org/abs/2305.06355)]

![images](assert/framework.png)
In this study, we initiate an exploration into video understanding by introducing VideoChat, an **end-to-end chat-centric video understanding system**. It integrates video foundation models and large language models via a learnable neural interface, excelling in **spatiotemporal reasoning, event localization, and causal relationship inference**. To instructively tune this system, we propose a **video-centric instruction dataset**, composed of thousands of videos matched with detailed descriptions and conversations. This dataset emphasizes **spatiotemporal reasoning and causal relationships**, providing a valuable asset for training chat-centric video understanding systems. Preliminary qualitative experiments reveal our system’s potential across a broad spectrum of video applications and set the standard for future research.


# :fire: Updates
- **2023/05/11**: Release the 🦜**VideoChat V1**, which can **handle both image and video understanding!**
    - [Model](https://drive.google.com/file/d/1BqmWHWCZBPkhTNWDAq0IfGpbkKLz9C0V/view?usp=share_link) and [Data](https://github.com/OpenGVLab/InternVideo/blob/main/Data/instruction_data.md).
