QSVideo: Human-Style Search that Tames Long Videos

This episode breaks down QSVideo, a human-inspired framework that finds the few critical frames in long videos by rewriting questions, weighting object/action/location importance, and scoring frames with a lightweight semantic ranker.

QSVideo uses diversity based metric, an anchor-and-expand (or recency-first for streams) traversal, and parallel ranking to deliver notable accuracy gains on LVBench and StreamingBench, run much faster than prior methods, and plug into existing video-language models without retraining.
