Use Seedance models to generate videos from a text prompt. Omitting mediaUrls (or imageUrls) activates pure text-to-video mode.
Seedance video generation can take anywhere from 2 minutes to 4 hours, depending on the upstream provider’s queue. You should always configure callBackUrl when using this model so the result can be delivered as soon as it is ready. Continuous polling of the Query Task endpoint is not recommended.
For Seedance-specific moderation behavior, refunds, and violation surcharges, see Moderation and Penalty.
