HunyuanVideo-Avatar is a novel model for generating dynamic, emotion-controllable, and multi-character dialogue videos. It builds upon advancements in audio-driven human animation, addressing key challenges such as character consistency and emotion accuracy. The model leverages a multimodal diffusion transformer (MM-DiT) architecture and introduces innovations like a character image injection module, an Audio Emotion Module (AEM), and a Face-Aware Audio Adapter (FAA). These components enable realistic video generation with fine-grained emotion control and the ability to animate multiple characters simultaneously.
HunyuanVideo-Avatar distinguishes itself through its ability to generate high-dynamic and emotion-controllable videos from diverse input images, including photorealistic, cartoon, and 3D renderings. The model’s architecture addresses condition mismatch issues and offers independent audio injection for multi-character scenarios, leading to superior realism and versatility. Its open-source release facilitates experimentation and application across various domains.
