# SymphoMotion: Joint Control of Camera Motion and Object Dynamics for Coherent Video Generation

SymphoMotion is a unified motion-control framework that jointly governs camera trajectories and object dynamics within a single model. It features a Camera Trajectory Control mechanism that integrates explicit camera paths with geometry-aware cues, and an Object Dynamics Control mechanism that combines 2D visual guidance with 3D trajectory embeddings.
