Seedance 2.0 Image to Video API

Seedance 2.0 Image-to-Video

Seedance 2.0 is Seed's latest video generation model, built on a unified multimodal architecture. The Image-to-Video mode generates production-grade cinematic videos from reference images and text prompts — preserving the input image's subject, composition, and style while adding expressive motion with native audio synchronization.

Key Features

• Unified multimodal architecture A single model that handles text, image, audio, and video inputs for comprehensive creative flexibility.

• Image-faithful generation Preserves the reference image's subject identity, composition, lighting, and style while animating it into motion.

• Multi-image reference support Guide generation with up to 4 reference images for consistent style, characters, or scenes.

• Native audio-visual synchronization Generates video with synchronized audio in a single pass.

• Director-level control Granular control over camera movement, lighting, shadows, and character performance through prompts.

• Exceptional motion stability Industry-leading motion coherence with stable subjects, consistent physics, and fluid transitions.
