Key points
- It provides 2,826 hours of real-world video, 128,892 clips, and camera trajectories with hierarchical annotations across 113 countries.
- It creates 649,597 time-level segments that separate subject motion, environmental change, static scenes, and camera behavior.
- It offers 982 loop videos revisiting 360-degree panoramas, which provide supervision for long-range spatial consistency.
- It cross-validates that the captions generated independently of camera annotations are aligned with actual camera motion.
- It provides a scalable data foundation for video generation, camera control, and pretraining interactive world models.
