Hunyuan Avatar

Hunyuan Avatar

Hunyuan Avatar is an advanced audio-driven avatar generation model that creates talking head videos from a single image and audio track. Upload a portrait and audio file, and the model generates a realistic video with synchronized lip movements, facial expressions, and natural head motion.

Why It Stands Out

• Audio-driven animation: Generates realistic talking head videos synced to any audio track.
• Single image input: Create animated avatars from just one portrait photo.
• Natural expressions: Produces lifelike facial movements, lip sync, and subtle head motion.
• Prompt support: Add optional prompts to guide style and expression. Use the Prompt Enhancer for optimization.
• Resolution options: Choose between 480p for faster processing or 720p for higher quality.
• Reproducibility: Use the seed parameter to recreate exact results.

Parameters

Parameter	Required	Description
audio	Yes	Audio file for lip sync (upload or public URL).

prompt	No	Optional text to guide expression or style.

How to Use

1. Upload your audio — drag and drop a file or paste a public URL.
2. Upload a portrait image — provide a clear, front-facing photo.
3. Add a prompt (optional) — describe desired expressions or style. Use the Prompt Enhancer for AI-assisted optimization.
4. Select resolution — choose 480p for speed or 720p for quality.
5. Click Run and wait for processing.
6. Preview and download the animated avatar video.
