World from Motion turns a monocular video into a dynamic 3D Gaussian scene that
can be rendered from new viewpoints. A video model refines views rendered from
an initial reconstruction, then those generated views are distilled back into
the scene. The core video pipeline combines MoSca reconstruction with DiffSynth video generation.
## Getting started
1. Build the environment using the installation guide.
2. Prepare the model bundle.
3. Reconstruct your video with the usage guide.
4. Reproduce **Ours (sample)** and **Ours (distill)** on DyCheck using
 REPRODUCTION.md, including the benchmark-specific setup,
 commands and reference numbers.
Model weights are distributed separately. The DyCheck Table 1 checkpoint is on
Hugging Face at `liyzzz/World-from-Motion`,
and the released evaluation masks are at
`liyzzz/World-from-Motion-DyCheck-Masks`.
The download location for the video-pipeline model bundle will be added when it is published.
