SkyReels V3 Pro Multi Avatar API

Skywork AI SkyReels V3 Pro Multi Avatar

Skywork AI SkyReels V3 Pro Multi Avatar generates a two-speaker avatar video from a single first-frame image plus separate left and right audio tracks. It is designed for higher-quality multi-character speaking scenes, with stronger realism, smoother facial animation, and more polished lip-sync than the Standard variant.

Why Choose This?

• Higher-quality multi-avatar performance The Pro variant is built for stronger realism, cleaner lip-sync, and more polished facial animation.

• Separate left and right speaker control Upload different audio clips for the left and right speakers to drive each character independently.

• Prompt-guided scene behavior Add a prompt to guide mood, scene setup, speaking style, or camera feel.

• Speaker detection control Use bboxes_type to control whether speaker detection is based on body or face.
