**Model ID:** `kling-video-v2-5-turbo-pro-image-to-video`

Kling v2.5 - Image to Video is a **video generation model** designed to transform a single still image into a smooth, cinematic video sequence.

It excels in preserving the input image’s composition and style while adding natural motion, realistic camera movements, and detailed visual effects, making it well suited for short dynamic clips, product showcases, and cinematic visuals.

Some other noteworthy use cases of Kling v2.5 - Image to Video include character-focused animation with improved motion fluidity and consistency, and prompt-driven cinematic shots such as dolly zooms, aerial sweeps, and tracking shots from image-plus-text inputs.

## Example request

<Tip>
  Use the [Workbench](https://www.oxen.ai/ai/workbench?model=kling-video-v2-5-turbo-pro-image-to-video) as a request builder: configure parameters for this model in the UI, then open the **API** tab to copy the exact cURL or Python call.

  <Tab title="Sync">
    This blocks until the video is ready (typically 5-15 minutes). Prefer **Async** or **Async with SSE** for anything beyond quick experimentation.

    See the [video generation reference](/inference-api/reference/video_generation) for more details.
