Use this endpoint to preview the currently selected region before you submit the final multimodal edit task.

Why preview matters

• It lets you verify that the selection points cover the intended object or area
• It helps catch bad masks before you spend a generation call
• It is the safest checkpoint between selection editing and final task creation

Workflow role

1. Initialize the session

   Start with Initialize Video for Editing.

2. Add selection points

   Use Add Video Selection until the region is close to correct.

3. Preview before generating

   Call this endpoint, then continue to Create Task only after the selection looks right.

For the complete parameter reference, see the Kling API documentation.
