长视频质量理解基准LongVQUBench发布
摘要
LongVQUBench是一个针对大视觉语言模型的长视频质量理解基准，包含1200多个视频和1500个问题，涵盖电影、纪录片等多种类型。它通过三个层次评估模型对局部、跨事件和全局质量的理解，并嵌入“针尖失真问答”任务。实验显示，现有模型在长视频和深度推理上表现不佳。
背景解释
现有视频质量基准多聚焦短视频和孤立失真，忽略了长视频的时间连续性和累积退化。LongVQUBench通过分层评估和稀疏失真插入，系统测试模型的长程感知和推理能力，为提升LVLMs在视频监控、内容审核等实际应用中的表现提供基础。

Abstract:The evaluation of long-term video quality understanding remains an open challenge for large vision-language models (LVLMs). Existing video quality benchmarks predominantly focus on short clips and isolated distortions, overlooking the temporal continuity, cumulative degradation, and reasoning complexity inherent in long-duration content. To address these limitations, we present LongVQUBench, a comprehensive benchmark for long-term video quality understanding. LongVQUBench contains over 1200 diverse videos spanning movies, documentaries, surveillance footage, egocentric recordings, and animated content, accompanied by 1500 multiple-choice and open-ended questions for validation and testing. To assess perceptual reasoning across different temporal scopes, we introduce three progressively complex evaluation levels: (i) local event quality understanding (LQU) for analyzing localized distortions; (ii) cross-event quality reasoning (CQR) for integrating multiple degraded events; and (iii) global quality understanding (GQU) for holistic perceptual evaluation over extended durations. Furthermore, a needle distortion question-answering (NDQA) paradigm is embedded across all three levels, where spatial or temporal artifacts are sparsely inserted to probe fine-grained detection and reasoning capabilities. Extensive experiments on 14 state-of-the-art LVLMs reveal significant performance degradation with increasing video length and reasoning depth, highlighting their limited capacity for long-range temporal integration and perceptual attribution. We envision LongVQUBench as a foundational step toward the systematic, hierarchical, and explainable evaluation of LVLMs' long-term video quality understanding.
