Independent workflow

This page now uses its own component and API route instead of the old shared Seedance wrapper chain.

Clear parameter boundaries

Text mode shows aspect ratio, while image mode exposes start and last-frame guidance without pretending every control still applies.

Credit visibility

Resolution, duration, and audio state all feed the same dedicated Seedance 1.5 Pro credit calculator used by the backend.

FAQ

What does this page support?

This page supports both text-to-video and image-to-video workflows, plus optional last-frame guidance when you start from an image.

Why does aspect ratio disappear after I upload a start image?

In image-to-video mode, the provider follows the uploaded image framing, so the page hides aspect ratio instead of pretending it still controls output.

Does the audio switch affect credits?

Yes. Audio generation costs more, so the credit preview updates immediately when you turn it on or off.
