Stream4D Mitigates Geometric Drift in Autoregressive Video Diffusion
August 19, 2026
Stream4D addresses geometric drift in long-horizon video generation by replacing static 3D Gaussian-Splatting critics with a dynamic alternative. This prevents the model from penalizing genuine object motion as reconstruction error, which previously caused videos to freeze or become static.
