TimeScope: How Long Can Your Video Large Multimodal Model Go?

Hugging Face introduces TimeScope, a benchmark designed to evaluate video large multimodal models (LMMs) across varying video lengths and temporal reasoning demands. The benchmark targets a known gap in existing evaluations: most video benchmarks use short clips, leaving long-video understanding largely untested. TimeScope aims to systematically probe how model performance degrades or holds as video duration increases.
