CREST method efficiently selects key frames from long videos

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. AI

IMPACT This method could improve the efficiency of AI models processing long video content by focusing on critical frames.

    CREST: Curvature-Regulated Event-Centric Sampling for Efficient Long-Video Understanding

    arXiv:2605.09223v2 Announce Type: replace Abstract: Selecting informative frames from long videos is a combinatorial problem that existing methods address either through efficient heuristics without explicit modeling of query-conditioned temporal structure, or through multi stage…
