# Kling-o1 Image to Video

Kling Omni Video O1 image-to-video tool leverages MVL (Multimodal Vision Language) technology to convert static images into dynamic cinematic videos. It maintains subject consistency while adding natural motion, physical simulation, and smooth scene dynamics.

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