 - **Event** — event-driven semantic peaks, adopting the replay-based annotations from Mr. HiSum.
 - **Emotion** — affective facial moments, annotated via a scalable two-stage automatic pipeline (frame-level facial expression recognition + multimodal LLM verification).

+- **Nature** — aesthetic scenic highlights, annotated via scenic localization (person/landscape detection) followed by frame-level aesthetic scoring. Features are sampled at 1 FPS, same as Event.
 
 The three perspectives are intentionally complementary rather than redundant (cross-perspective IoU as low as 0.002–0.052 on Mr. HiSum), enabling structured analysis of heterogeneous highlight patterns beyond the traditional single-perspective paradigm. This repository provides only the precomputed CLIP ViT-B/32 features (and Emotion ground-truth labels) used in the paper's experiments — see the paper for full annotation pipeline details.
