Reference caps
| Model | Reference images | Reference video | Reference audio |

On the Seedance 2.0 family, reference audio cannot be sent on its own — an image or video reference has to accompany it.
A reference video changes the price
Attaching a reference video switches billing from the standard rate to the reference rate, and the total reference seconds plus the output seconds are billed with a 9 second minimum.

How billing works
Video is billed per second of output and only for what is actually generated. There is no monthly subscription, and credits stay valid for one year from the date of purchase. Failed generations are refunded.
