Start with a text-only task, or add endpoint frames and references only when they have a clear role in the shot. seedance-2.0-mini
These specifications reflect the current HiAPI Seedance 2.0 Mini request contract.
Choose one control mode for the first test, then add references gradually to keep the request explainable.
This is the minimum request for an asynchronous text-to-video task. Use the API docs for task retrieval, callbacks, errors, and the complete parameter contract.

POST an asynchronous task to /v1/tasks with model set to seedance-2.0-mini and place parameters inside input.
Lead with subject and setting, then describe action, camera direction, and speed in time order. State no cuts for a continuous take.
Draft
5s · 720p
Final
15s · 720p
Validate subject motion and camera continuity with 5s · 720p, then move to 15s · 720p.
Check motion stability and subject consistency online, then create an asynchronous task with the same model ID: seedance-2.0-mini.
