Vidi: Large Multimodal Models for Video Understanding and Editing

Homepage: https://bytedance.github.io/vidi-website/

Github: https://github.com/bytedance/vidi

Demo: https://vidi.byteintl.com/

We introduce Vidi, a family of Large Multimodal Models (LMMs) for a wide range of video understanding and editing (VUE) scenarios. The first release focuses on temporal retrieval (TR), i.e., identifying the time ranges in input videos corresponding to a given text query.

This model is the Vidi1.5 model version for temporal retrieval.
