📝 摘要(中文)
视频理解正被多模态大语言模型(MLLMs)迅速转变,研究从短视频片段扩展到长视频和知识密集型场景。这些场景要求模型处理稀疏证据、长程依赖、多模态对齐以及在有限计算预算下的可靠推理。本文从人类视角出发,围绕观看、记忆和推理三个功能能力,提出了一种统一的结构来分析视频MLLM如何获取证据、保持上下文并产生有根据的输出。我们还识别了在时空感知、长视频处理、记忆建模、流式理解和可靠推理等方面的挑战,并探讨了在不同应用领域的表现。

📄 摘要(原文)
Video understanding is being rapidly transformed by multimodal large language models (MLLMs), as research moves from short clips to long, multimodal, and knowledge-intensive video scenarios. These scenarios require models to handle sparse evidence, long-range dependencies, multimodal alignment, and reliable inference under limited computational budgets. This work presents a human-view perspective on LLM-based video understanding, organized around three functional abilities: watching, remembering, and reasoning. Rather than treating video tasks as isolated benchmarks, this view provides a unified structure for analyzing how video MLLMs acquire evidence, preserve context, and produce grounded outputs. We introduce a formulation that characterizes video understanding systems by their perceptual representations, memory states, reasoning traces, and final predictions. Based on this formulation, we identify challenges in spatio-temporal perception, efficient long-video processing, memory modeling, streaming understanding, and faithful reasoning. Representative methods are organized by their roles in video MLLM systems. Watching covers fine-grained, comprehensive, audio-visual, and efficient perception. Remembering includes offline and streaming memory, while reasoning covers text-only reasoning and thinking with videos. We further examine application domains such as egocentric, sports, instructional, medical, and narrative videos, and cover training datasets and evaluation benchmarks across task types, supervision formats, modalities, and capability dimensions. Finally, we outline open problems and future directions for scalable, memory-aware, and evidence-grounded video intelligence.
