Recently, Alibaba announced its latest technological achievement, Animate Anyone 2. This groundbreaking technology enables precise character replacement in videos. According to the project’s official website showcasing case studies, users only need to provide the original video and target character images, allowing the system to achieve real-time character replacement while preserving the original video’s motion trajectory. Experimental data shows that the system can completely transfer a soccer player's shooting motion to an animated character while maintaining the true physical characteristics of the ball's movement. This addresses the complex needs in film production.
