TimeScope is an open-source benchmark designed to measure how well vision-language models understand long videos, evaluating localized retrieval, information synthesis, and fine-grained temporal perception across videos from 1 minute to 8 hours.

## Evidence

Verbatim from https://huggingface.co/blog/timescope-video-lmm-benchmark:

> TimeScope is an open-source benchmark designed to measure how well vision-language models understand long videos. By adding short “needle” clips into videos ranging from 1 minute to 8 hours, it evaluates three skills: localized retrieval, information synthesis, fine-grained temporal perception.
