Recent advancements in video-language understanding have been established on the foundation of image-text models, resulting in promising outcomes due to the shared knowledge between images and videos. However, video-language understanding presents unique challenges due to the inclusion of highly complex semantic details, which result in information redundancy, temporal dependency, and scene complexity. Current techniques have only partially tackled these issues, and our quantitative analysis indicates that some of these methods are complementary. In light of this, we propose a novel framework called RTQ (Refine, Temporal model, and Query), which addresses these challenges simultaneously. The approach involves refining redundant information within frames, modeling temporal relations among frames, and querying task-specific information from the videos. Remarkably, our model demonstrates outstanding performance even in the absence of video-language pre-training, and the results are comparable with or superior to those achieved by state-of-the-art pre-training methods.

我们提出了一种名为RTQ（Refine，Temporal model和Query）的新型框架，同时解决了视频语言理解中的信息冗余、时序依赖和场景复杂度等挑战，这种方法通过对帧内冗余信息的优化、建模帧之间的时序关系和从视频中查询任务特定信息来实现。令人惊讶的是，即使在无视频语言预训练的情况下，我们的模型也表现出色，并且结果与或优于最先进的预训练方法。
