Kling V3.0 Motion Control
Kling V3.0 Motion Control extracts motion trajectories from reference videos and applies them to reference images to generate videos while maintaining subject consistency. Supports standard and professional modes with per-second billing.
This is an asynchronous API; only the task_id will be returned. You should use the task_id to request the Task Result API to retrieve the video generation results.
