# Seedance 1.5 Pro Video Generation

> High-quality text-to-video and image-to-video generation with Seedance 1.5 Pro

<Tip>
  1. After submission, a `task_id` will be returned. If you provided a `callback_url`, when the task status becomes `finished` or `failed`, a POST request will be sent to the `callback_url`.
  2. Regardless of whether `callback_url` is provided, you can retrieve the response result through the unified [Query Task Status](/api-manual/task-management/status) endpoint.
