MVBench: A Comprehensive Multi-modal Video Understanding Benchmark

Guo Chen, Jilan Xu, Kunchang Li, Limin Wang, Ping Luo, Yali Wang, Yi Liu, Yinan He, Yi Wang, Yizhuo Li, Yu Qiao, Zun Wang

Most multi-modal AI models fail at temporal understanding in videos, but a new benchmark and training method lift performance by more than 15 percent.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

the existing MLLMs are far from satisfactory in temporal understanding, while our VideoChat2 largely surpasses these leading models by over 15% on MVBench.

C2weakest assumption

That automatically converting public video annotations into multiple-choice QA pairs accurately measures the intended temporal skills without introducing annotation biases or allowing single-frame shortcuts.

C3one line summary

MVBench is a benchmark of 20 temporal video understanding tasks built by transforming static tasks into dynamic ones, with VideoChat2 outperforming prior MLLMs by over 15%.
