Researchers have introduced GMM-EVA, a novel framework designed to improve the efficiency and effectiveness of Large Vision-Language Models (LVLMs) in understanding long videos. Unlike existing methods that sample frames uniformly, GMM-EVA utilizes Gaussian Mixture Models to identify and segment events within videos. This allows for a differentiated allocation strategy, preserving high-resolution keyframes for primary event details while using lower-resolution frames for temporal context, thereby optimizing token usage. The framework is training-free and plug-and-play, demonstrating significant performance improvements over uniform sampling and achieving comparable results with roughly half the token budget on various long video benchmarks.
