Kling Omni Video O1 video editor supports conversational video editing through natural language commands. With simple text instructions such as “remove pedestrians” or “change day to dusk”, you can remove objects, replace backgrounds, modify styles, adjust weather/lighting, and transform scenes.

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