Seedance 2.0 — Next-Generation AI Video Model
Seedance 2.0 delivers cinematic AI video generation with 720p output, 4–15 second durations, and three input modes: text, image, and multimodal reference.
Overview
Seedance 2.0 is ByteDance's latest video generation model, delivering major improvements in visual quality, motion realism, and creative control. Through Seedance2API you get access to the complete Seedance 2.0 model matrix with competitive pricing and a developer-friendly interface.
Core Capabilities
Text-to-Video
Generate cinematic videos from natural language descriptions. Seedance 2.0 understands complex scenes, camera movement, and artistic styles. Optionally enable the web_search parameter to let the model autonomously look up fresh information for time-sensitive content.
Image-to-Video
Animate 1–2 static images: 1 image as a first-frame driver, or 2 images as first-last-frame transition. Ideal for e-commerce product showcases, social media content, and creative projects.
Multimodal Reference-to-Video
In a single request, combine up to 9 images + 3 videos + 3 audio clips as reference assets, and assign each asset a role using natural language in your prompt. This is the core differentiator versus Sora 2, Kling 3.0, and Veo 3.1.
