# Kling V2.6 Pro Motion Control

The Kling v2.6 Pro Motion Control model generates animations by applying motion from a reference video to a reference image. It extracts motion paths from 3-30 second video clips to produce smooth, realistic video animations while maintaining subject identity consistency.

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