Wonder Studio is an AI tool that automatically animates, lights, and composites CG characters into real-world scenes. Users only need a camera and do not require complex 3D software or expensive production hardware. By uploading CG character models to one or multiple shots, the system automatically detects clips and tracks actors throughout the sequence. The system automatically detects actors' performances from single-camera shots and then transfers that performance to the user's chosen CG character, achieving automatic animation, lighting, and compositing. Wonder Studio has wide applications in film making, VFX production, and other related fields.
