The Kling v2.6 Pro Image-to-Video tool transforms static images into dynamic videos, generating natural motion and smoother scene dynamics while maintaining subject consistency.
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.
