Kling Omni Video O1 image-to-video leverages MVL (Multimodal Vision Language) technology to transform static images into cinematic videos. It maintains subject consistency while adding natural motion, physics simulation, and smooth scene dynamics.
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 to retrieve the generated result.
