📢 Latest Updates

  • Jan-2: Thanks to Xiao Xia , Shengbo Tong and Beining Wang, we have refactored the code to now support both the LLAMA and ChatGLM3 architectures. We translated the training data into Chinese and fine-tuned a Chinese version based on the ChatGLM3-6b.
  • Dec-14: Released the training code and data. All the resources including models, datasets and extracted features are available here. 🔥🔥
  • Dec-4: VTimeLLM: demo released.

VTimeLLM Overview 💡

VTimeLLM is a novel Video LLM designed for fine-grained video moment understanding and reasoning with respect to time boundary.

VTimeLLM adopts a boundary-aware three-stage training strategy, which respectively utilizes image-text pairs for feature alignment, multiple-event videos to increase temporal-boundary awareness, and high-quality video-instruction tuning to further improve temporal understanding ability as well as align with human intents.

Contributions 🏆

  • We propose VTimeLLM, the first boundary-aware Video LLM, to the best of our knowledge.
  • We propose the boundary-aware three-stage training strategy, which consecutively leverages i) large-scale image-text data for feature alignment, ii) large-scale multi-event video-text data together with the temporal-related single-turn and multi-turn QA to enhance the awareness of time boundary, and iii) instruction tuning on the high-quality dialog dataset for better temporal reasoning ability.
  • We conduct extensive experiments to demonstrate that the proposed VTimeLLM significantly outperforms existing Video LLMs in various fine-grained temporal-related video tasks, showing its superior ability for video understanding and reasoning.

Installation 🔧

We recommend setting up a conda environment for the project:

conda create --name=vtimellm python=3.10
conda activate vtimellm

git clone https://github.com/huangb23/VTimeLLM.git
cd VTimeLLM
pip install -r requirements.txt

Additionally, install additional packages for training cases.

pip install ninja
pip install flash-attn --no-build-isolation

Running Demo Offline 💿

To run the demo offline, please refer to the instructions in offline_demo.md.
