Researchers have introduced VideoDetective, a novel framework designed to enhance the understanding of long videos by multimodal large language models (MLLMs). This approach addresses the challenge of limited context windows by integrating both query-based relevance and the video's intrinsic structural relationships. VideoDetective constructs a visual-temporal affinity graph and employs a hypothesis-verification-refinement loop to identify critical video segments for accurate question answering. Experiments demonstrated significant accuracy improvements, with gains of up to 7.5% on the VideoMME-long benchmark. AI
