Researchers have developed CREST, a novel method for efficiently selecting key frames from long videos. This training-free approach leverages the temporal geometry of query-frame relevance, specifically focusing on local curvature to identify salient events and distinguish them from redundant segments. CREST demonstrates superior accuracy compared to heuristic methods on benchmarks like LongVideoBench and VideoMME, while significantly reducing preprocessing costs compared to more complex retrieval pipelines.
