Three new vision-centric evaluation benchmarks in temporal frame retrieval, video future prediction, and causal memory distortion are introduced, all designed around evaluating visual understanding capabilities in large video models, which complements the existing approaches to evaluate video understanding in frontier...

Experiments on a new approach for fine-grained evaluation demonstrate that this approach enhances a model’s ability to understand fine-grained differences.

A video benchmark should reward the capability it claims to measure, yet models can exploit answer options, question text, or partial visual evidence. We introduce the attack pyramid, five levels of shortcut attacks with increasing access to each item, and audit 115 video benchmarks with it. On 35 benchmarks, attackers...

VideoEvent is a lightweight and efficient training-free framework that segments an input video into question-relevant temporal events and selectively supplements them with low-level visual cues such as background and object layout, making it highly suitable for practical deployment.

This work conducts a large-scale evaluation of more than 20 recent MLLMs and shows that video instruction following remains challenging for current models, especially for instructions with many constraints, semantic constraints, or complex conditional structures that require selecting the correct branch or path based o...

This work compares six off-the-shelf VLMs against a transparent baseline that uses classical SIFT keypoint matching and a signal-quality index over retrieved images, and shows that a learned visual representation is not the bottleneck for this task: given retrieved images, a shape-appropriate classical similarity suffi...
