FAQ
Common questions about Seedance 1.5 Pro.
What is Seedance 1.5 Pro?
Seedance 1.5 Pro is ByteDance’s audio-video generation model. On UniRoute, you can use a text prompt and an output option to create video in the browser or through the media API.
Can I supply a starting image or control the audio?
Not currently. The UniRoute catalog exposes a text prompt and a resolution and duration option. It does not expose reference images, first or last frame inputs, or an audio switch.
What should I put in the prompt?
Describe the scene, who is in it, what happens and how the camera moves. ByteDance’s description also discusses dialogue and sound within the scene; UniRoute does not provide separate audio parameters.
How much does Seedance 1.5 Pro cost?
From $0.05 / clip. Requests are priced for the whole clip according to the selected option. See the Pricing section for every option and rate (prices updated 2026-11-08).
How do I call Seedance 1.5 Pro from code?
Use the media API to quote the selected model and option, create a task with an Idempotency-Key and a maximum cost, then poll its status until the video is ready. The API section includes a complete request example.
Is there a free trial or free credits?
No. Generation is paid from your wallet balance. You can open the workspace and review the price without paying, create an account to see a live quote for your exact settings, and you are charged only for requests that are accepted.
