Researchers present World from Motion, a method that generates freely renderable dynamic 3D Gaussian Splatting (3DGS) representations from monocular video by conditioning a video model on pixel-aligned renderings encoding appearance, geometry, and 3D scene motion. The approach trains on aligned multiview video pairs with simulated monocular reconstruction artifacts, then distills model generations back into a consistent dynamic 3DGS at test time. The method claims state-of-the-art results in 4D reconstruction and generalizes to in-the-wild videos with large viewpoint changes and dynamic content.
