VideoChat3-Stage3-Training-Data

This repository includes all annotation files used across the four training stages of VideoChat3, from Stage 0 to Stage 3.

You can refer to the provided source-data links to download videos, images, and other multimedia data for training. In videochat3_data_annotations, we also provide a source field to indicate the source dataset for each entry.

To facilitate Stage 3 training reproduction using the high-quality open-source datasets we collected and curated, we additionally provide a more detailed introduction at VideoChat3-Stage3-Training-Data.

VideoChat3 Training Overview

Data Organization

Component Description
training_data_annotations Training annotation data for each stage
videochat3_data_annotations Annotation files for individual datasets
training_data_source_tables Source datasets and paths

In videochat3_data_annotations, the Stage 0 and Stage 2 annotation data partially overlap with our previously released VideoChat3-Academic2M and VideoChat3-LV116K. For convenience of downloading and use, we re-upload them here.

Because the training_data_source_tables contain data from a wide range of sources, there may be occasional errors. If you spot any issues, please feel free to contact me at zzhiqiu997@gmail.com.

Citation

If you use this data, please cite VideoChat3 and the original video datasets used by the annotations.
