UniMoCa: Unifying Motion and Camera Controls as Visual Proxies for Faithful Human Video Generation
Liming Tan, Ye Chen, Hao Zhang +3
Controlling human motion and camera movement is essential for faithful human-oriented video generation, yet remains challenging in multi-person scenes with large body motions, occl…

World Narrative Model for Highly Controllable Video Generation: A Paradigm Shift from Pixel Sampling to Physical World Orchestration
Ye Chen, Xuanhong Chen, Yupeng Zhu +23
The paper proposes the World Narrative Model, a framework that separates the specification of a 4D physical scene (geometry, motion, camera, lighting) from pixel generation, enabli…

Vectorized Video Representation with Easy Editing via Hierarchical Spatio-Temporally Consistent Proxy Embedding
Ye Chen, Liming Tan, Yupeng Zhu +2
Current video representations heavily rely on unstable and over-grained priors for motion and appearance modelling, \emph{i.e.}, pixel-level matching and tracking. A tracking error…
