How Does It Work?
Ditto’s character replacement feature is powered by a sophisticated understanding of human pose and appearance. When you provide Ditto with a video and a text prompt describing the new character, it goes through a multi-step process:
- Pose and Motion Analysis: Ditto first analyzes the source video to understand the pose and motion of the original character.
- Character Generation: It then uses a powerful diffusion model to generate a new character based on your text prompt.
- Compositing and Blending: Finally, it composites the new character into the original scene, carefully blending it with the background and lighting to create a seamless and realistic result.
