DynFrame: Adaptive Reasoning-Driven Multimodal Framework with Dynamic Frame Augmentation for Complex Video Understanding
arXiv:2605.26680v1 Announce Type: cross Abstract: Recent video multimodal large language models (MLLMs) increasingly couple step-by-step reasoning with on-demand visual evidence retrieval, allowing models to revisit relevant video segments during inference. However, two structural gaps remain in existing thinking-with-video systems. (i) Sampling density is not a learnable decision: existing methods may let the model decide where to look, but the per-window frame rate is largely fixed. As a result, fine-grained evidence is often recovered through repeated retrieval calls, which increases infere
The rapid advancement in multimodal large language models necessitates more sophisticated and efficient video understanding capabilities to handle complex, real-world scenarios, particularly balancing reasoning with visual evidence retrieval.
Improving complex video understanding will unlock new applications for AI in various sectors, from autonomous systems to automated content analysis, by enabling more nuanced and adaptive interpretation of dynamic visual information.
Current fixed-frame-rate limitations in video MLLMs are being addressed by dynamic frame augmentation, allowing models to adaptively sample visual input, which can lead to more efficient and accurate reasoning.
