New dataset LF-VideoQA challenges AI models on long-form video understanding

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced LF-VideoQA, a new dataset designed to evaluate the long-form understanding capabilities of Vision--Language Models (VLMs) on narrative videos. This dataset focuses on theory-of-mind questions, which require synthesizing information distributed across extended periods, averaging 23 minutes per question. Initial evaluations of state-of-the-art VLMs reveal significant challenges, with even oracle models falling short of complete answers and current non-oracle models achieving only half the recall of the oracle. The results indicate that visual evidence is crucial, and recall is the primary bottleneck for these models. AI

IMPACT This dataset will push the development of AI models capable of deeper, more contextual understanding of long-form video content.

    LF-VideoQA: Evaluating Long-Video Understanding with Long-Form Theory-of-Mind Questions

    arXiv:2611.00383v1 Announce Type: cross Abstract: The hardest part of understanding a long video is not pinpointing any one moment but synthesizing many, e.g., answering a question that requires tracking what develops across hours of content and articulating how the pieces fit to…
