Seedance V1 Pro is an AI video model designed for coherent multi-shot video generation, offering smooth motion and precise adherence to detailed prompts. It supports resolutions of 480p, 720p, and 1080p.

This is an asynchronous API; only the task_id will be returned. You should use the task_id to request the [Task Result API](/docs/api-reference/model-apis-task-result) to retrieve the video generation results.
