We introduce MagicPose4D, a novel framework for 4D generation providing more accurate and customizable 4D motion retargeting. We propose a dual-phase reconstruction process that initially uses accurate 2D and pseudo 3D supervision without skeleton constraints, and subsequently refines the model with skeleton constraints to ensure physical plausibility. We incorporate a novel Global-Local Chamfer loss function that aligns the overall distribution of mesh vertices with the supervision and maintains part-level alignment without additional annotations. Our method enables cross-category motion transfer using a kinematic-chain-based skeleton, ensuring smooth transitions between frames through dynamic rigidity and achieving robust generalization without the need for additional training.

MagicPose4D accepts two distinct types of input prompts: (i) appearance prompts and (ii) motion prompts. Both images and textual descriptions can function as appearance prompts, delineating the desired object and its visual characteristics. In a departure from existing approaches, MagicPose4D enables users to specify precise motions and trajectories by providing a video/mesh sequence that represents the anticipated movement. MagicPose4D comprises three critical components: (i) the 4D Reconstruction module, (ii) the Cross-Category Motion Transfer module, and (iii) the Image-to-3D Generation module. Each module is tailored to facilitate distinct aspects of dynamic modeling, enabling adaptive 4D reconstructions that align with user-defined specifications.
