Use this endpoint to submit the final multimodal video-editing job after your session and selections are ready.

​
Full workflow

1

Initialize the editing session

Start with Initialize Video for Editing to obtain the session_id for the clip you want to edit.
2

Build the selection area

Use Add Video Selection and, when needed, Preview Selected Video Area to refine the edit region.
3

Submit the final task

Send the session_id, edit_mode, and final prompt through this endpoint, then save the returned task id for status checks.

​
Before you call it

  • Make sure the selection session is already initialized
  • Confirm your region selection is correct before spending a generation call
  • Treat this route as the final generation step, not the setup step
For the complete parameter reference, see the Kling API documentation.
