Dataset Card for LongVideoBench
Large multimodal models (LMMs) are handling increasingly longer and more complex inputs. However, few public benchmarks are available to assess these advancements. To address this, we introduce LongVideoBench, a question-answering benchmark with video-language interleaved inputs up to an hour long. It comprises 3,763 web-collected videos with subtitles across diverse themes, designed to evaluate LMMs on long-term multimodal understanding.

VideoSIAH-Eval
Evaluation benchmark for LongVT, containing 652 unique QA pairs across 244 long-form videos with human-in-the-loop validation.
Update (2026-03): The initial release contained 1,280 entries due to unintentional duplication during data export. This version has been cleaned to 652 unique QA pairs. Since each entry was an exact copy, all evaluation metrics reported in the paper remain unchanged.
