常见问题

How much does the Seedance API cost?

Credits depend on resolution, duration and audio. 480p 4s no-audio costs 8 credits, default 720p 8s no-audio costs 28 credits, and 720p 12s with-audio costs 84 credits.

What makes Seedance different from other video models?

Seedance specializes in human motion and dance, producing more natural body movements than general-purpose video models.

Does Seedance support audio?

Yes. Set generateAudio to true to generate audio alongside the video. This doubles the credit cost.
