What Is Seedance?
Seedance is an AI video foundation model family developed by ByteDance's Seed team. It can transform text, images, audio, and video into cinematic-quality clips. The name combines Seed and Dance, expressing the idea of “making creativity move.”
Three Core Breakthroughs of Seedance 2.0
Seedance 2.0 introduces practical upgrades for creative production: quad-modal generation, director-style reference control, and production-ready output specs.
Quad-modal Input
Unlike most tools that rely on text + image only, Seedance 2.0 can jointly process text, image, audio, and video in one generation workflow.
Omni Reference System
Upload multiple references and assign their role with @ tags in your prompt, which enables fine-grained and explicit creative control.
Output Profile
Supports up to 2K, 4-15s duration, ~70 credits per 5s, and reported availability above 90% for a stable production pipeline.
Omni Reference (@) in Practice
You can upload up to 12 references in one workflow and bind each file to a specific role in natural language. This interaction pattern is often described as director-level control.
Reference Capacity
Up to 9 images, 3 videos, and 3 audios can be provided as references.
Prompt Example
Generate an astronaut walking on Mars, use @app_music.mp3 as background music, use @char_ref.png for character appearance, and apply particles from @vfx_lens.mp4 for atmosphere.Output Specs

Horizontal Comparison
In overall capability, Seedance 2.0's key edge is complete multi-modal input plus fine-grained director control, while Veo 3 leads in peak resolution and Kling 3.0 leads in max duration.

Full Multi-modal Pipeline
The complete text-image-audio-video combination is Seedance 2.0's strongest differentiator.
Director-style Precision
@-tag mapping gives explicit control over identity, sound, style, and visual effects.
Trade-offs Are Clear
Seedance wins on control completeness, but not on top-end resolution or longest duration.
