MoVieS: Motion-Aware 4D Dynamic View Synthesis in One Second

Understand

We present MoVieS, a Motion-aware View Synthesis model that reconstructs 4D dynamic scenes from monocular videos in one second.

• It represents dynamic 3D scenes with pixel-aligned Gaussian primitives and explicitly supervises their time-varying motions.
• This allows, for the first time, the unified modeling of appearance, geometry and motion from monocular videos, and enables reconstruction, view synthesis and 3D point tracking within a single learning-based framework.
• By bridging view synthesis with geometry reconstruction, MoVieS enables large-scale training on diverse datasets with minimal dependence on task-specific supervision.
