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.

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.
