研究人员开发了一个名为QCA的新框架，用于在长视频中选择关键帧以提高视频理解能力。该方法是查询和内容感知的，意味着它优先考虑与特定查询相关且能捕捉重要内容变化的帧。QCA动态地为不同的视频片段分配关键帧，并选择最大化多样性同时保持语义相关性的帧。该框架无需额外训练，即可集成到现有的Video-LLMs中，并在LongVideoBench等基准测试中展现出最先进的性能，其关键帧选择效率优于GPT-4o。 AI
影响 该方法可以提高处理长视频内容的AI模型的效率和有效性，有可能降低计算成本并提高视频搜索和分析等应用的准确性。

Video understanding is often plagued by severe temporal redundancy, where processing dense frame sequences is both semantically inefficient and computationally expensive. This challenge is further amplified when only a small subset of frames is truly relevant to the given query. …
