# Kling-o1 Video Edit

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

<Tip>
  This is an **async** API that only returns the task\_id of the async task. Use the task\_id to call the [Get Async Task Result API](/docs/models/reference-get-async-task-result) to retrieve the generated result.
