MIMO is a versatile video synthesis model that can mimic any individual interacting with objects during complex motions. It synthesizes character videos with controllable attributes such as characters, actions, and scenes based on simple inputs provided by the user (e.g., reference images, pose sequences, scene videos, or images). MIMO achieves this by encoding 2D video into compact spatial codes and decomposing them into three spatial components (main subject, underlying scene, and floating occlusions). This method allows users to flexibly control spatial motion representation and create 3D perceptive synthesis, suitable for interactive real-world scenarios.
