Summary

A human-view perspective on LLM-based video understanding, published on 2026-06-05, proposes a unified framework organized around three functional abilities: watching, remembering, and reasoning. This approach moves beyond isolated benchmarks to analyze how video MLLMs acquire evidence, preserve context, and produce grounded outputs. The work introduces a formulation based on perceptual representations, memory states, reasoning traces, and predictions. It identifies key challenges in spatio-temporal perception, efficient long-video processing, memory modeling, streaming understanding, and faithful reasoning. Representative methods are categorized by their roles in perception, memory, and reasoning, covering applications like egocentric, sports, instructional, medical, and narrative videos, alongside relevant datasets and benchmarks. The analysis concludes by outlining open problems for scalable, memory-aware, and evidence-grounded video intelligence.

Key takeaway

For AI Scientists developing multimodal large language models for video understanding, this human-view perspective provides a crucial framework. You should adopt its watching, remembering, and reasoning structure to systematically analyze evidence acquisition, context preservation, and grounded output generation. Prioritize addressing challenges in efficient long-video processing, memory modeling, and faithful reasoning to build scalable and evidence-grounded video intelligence systems.
