 In total, Camera Clone Dataset comprises 391K visually authentic videos shooting from 39.1K different locations in 40 scenes with 97.75K diverse camera trajectories, and 1,155K triple video sets are constructed based on these videos. Each video has a resolution of 576 X 1,008 and 154 frames.
 
+**3D Environment:** We collect 40 high-quality 3D environments assets from [Fab](https://www.fab.com). To minimize the domain gap between rendered data and real-world videos, we primarily select visually realistic 3D scenes, while choosing a few stylized or surreal 3D scenes as a supplement. To ensure data diversity, the selected scenes cover a variety of indoor and outdoor settings, such as city streets, shopping malls, cafes, office rooms, and the countryside.
+
+**Character:** We collect 66 different human 3D models as characters from [Fab](https://www.fab.com) and [Mixamo](https://www.mixamo.com).
+
+**Animation:** We collect 93 different animations from [Fab](https://www.fab.com) and [Mixamo](https://www.mixamo.com), including common actions such as waving, dancing, and cheering. We use these animations to drive the collected characters and create diverse datasets through various combinations.
+
+**Camera Trajectories:** To prevent clipping, trajectories are constrained by a maximum movement distance \\(d_{max}\\), determined by the initial shot position in the scene. The types of trajectories contain:
+  * **Basic**: Simple pans/tilts (5°-75°), rolls (20°-340°), and translations along cardinal axes.
+  * **Arc**: Orbital paths, combining a primary rotation (10°-75°) with smaller, secondary rotations (5°-15°).
+  * **Random**: Smooth splines interpolated between 2-4 random keypoints. Half of these splines also incorporated with multi-axis rotations.
