  This paper introduces InternVid, a large-scale video-centric multimodal
dataset that enables learning powerful and transferable video-text
representations for multimodal understanding and generation. The InternVid
dataset contains over 7 million videos lasting nearly 760K hours, yielding 234M
video clips accompanied by detailed descriptions of total 4.1B words. Our core
contribution is to develop a scalable approach to autonomously build a
high-quality video-text dataset with large language models (LLM), thereby
showcasing its efficacy in learning video-language representation at scale.
Specifically, we utilize a multi-scale approach to generate video-related
descriptions. Furthermore, we introduce ViCLIP, a video-text representation
learning model based on ViT-L. Learned on InternVid via contrastive learning,
this model demonstrates leading zero-shot action recognition and competitive
video retrieval performance. Beyond basic video understanding tasks like
recognition and retrieval, our dataset and model have broad applications. They
are particularly beneficial for generating interleaved video-text data for
learning a video-centric dialogue system, advancing video-to-text and
text-to-video generation research. These proposed resources provide a tool for
researchers and practitioners interested in multimodal video understanding and
generation.
