Seedance 2 Fast overview
Seedance 2 Fast helps teams test video ideas quickly with text prompts and image guidance. Choose reference images or first and last frames to explore framing, motion, and scene direction. Enable generated audio when needed, then develop the strongest concept into a more polished production pass.
Creative examples
Hook testing for ads and social promos
Generate multiple opening moments, framing ideas, and motion cues quickly so marketing teams can compare which creative direction feels strongest before investing in full production assets.
Storyboard previews with image references
Use reference images to hold key visual intent while testing movement, pacing, and subject emphasis. This is especially useful for teams turning approved design frames into motion concepts.
First and last frame variations
Set the opening and ending images, then describe the motion between them. Compare alternate scene directions for different campaigns or channels.
Generated sound for early concepts
Enable generated audio to explore the atmosphere of a short clip alongside its visuals. Review the sound and refine the final mix in your editor.
SEO landing-page motion and feature loops
Fast iterations make it practical to produce supporting loops for product pages, feature explainers, and comparison content where motion helps communicate the value proposition more clearly.
Internal creative reviews before final render
Creative leads can review composition, scene logic, and mood in a cheaper environment first, which reduces wasted spend on high-end passes that would be rejected for concept reasons anyway.

Seedance 2 Fast is useful for testing prompts, image references, and first and last frames early in a project. Enable generated audio when you want to review the atmosphere of the clip alongside its visuals.
How should I use Seedance 2 Fast in a workflow?
A good pattern is to use Fast for concept search, opening-hook testing, scene variation, and stakeholder review. Once a concept proves itself, you can promote the winning idea into a higher-quality production pass.
Can Seedance 2 Fast generate audio with the video?

Use frames when you have a specific opening or ending composition. For broader visual guidance, choose reference images instead. Keep these modes separate and describe the desired motion in your prompt.
