Frequently Asked Questions
How much does the Seedance API cost?
Credits depend on resolution, duration and audio. 480p 4s no-audio costs 7 credits, 720p 12s with-audio costs 84 credits. Audio-enabled doubles the cost.
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.
