Understanding the dynamic physical world, characterized by its evolving 3D structure, real-world motion, and semantic content with textual descriptions, is crucial for human-agent interaction and enables embodied agents to perceive and act within real environments with human‑like capabilities. However, existing datasets are often derived from limited simulators or utilize traditional Structure-from-Motion for up-to-scale annotation and offer limited descriptive captioning, which restricts the capacity of foundation models to accurately interpret real-world dynamics from monocular videos, commonly sourced from the internet.To bridge these gaps, we introduce DynamicVerse, a physical‑scale, multimodal 4D modeling framework for real-world video. We employ large vision, geometric, and multimodal models to interpret metric-scale static geometry, real-world dynamic motion, instance-level masks, and holistic descriptive captions. By integrating window-based Bundle Adjustment with global optimization, our method converts long real-world video sequences into a comprehensive 4D multimodal format. DynamicVerse delivers a large-scale dataset consists of 100K+ video with 800K+ annotated masks and 10M+ frames from internet videos. Experimental evaluations on three benchmark tasks---video depth estimation, camera pose estimation, and camera intrinsics estimation---validate that our 4D modeling achieves superior performance in capturing physical-scale measurements with greater global accuracy than existing methods.
