Multimodal reference generation and editing through the Omni endpoint. Supports original audio or silence, but not native audio generation, 4K or video-character Elements.

## Model Specifications

| Item                             | Details                                                                    |
| -------------------------------- | -------------------------------------------------------------------------- |
| ID                               | `kling-o1`                                                                 |
| Endpoints                        | [Omni Generation and Editing](/en/api-reference/endpoint/kling-omni-video) |
| Standard generation resolution   | 720p / 1080p                                                               |
| Standard generation duration (s) | 3-10                                                                       |

The duration above does not apply to motion control; media input may impose additional constraints on the linked endpoint pages. Put the model in the path and keep the native body structure, without metadata.

## Request Example

Set the `MIXROUTE_API_KEY` environment variable. Replace `example.com` media URLs with real, publicly accessible files.

```bash theme={null}
curl --request POST "https://api.mixroute.ai/kling/omni-video/kling-o1" \
  --header "Authorization: Bearer $MIXROUTE_API_KEY" \
  --header "Content-Type: application/json" \
  --data '{
  "contents": [
    {
      "type": "prompt",
      "text": "Change the red mug in @video_1 to blue. Preserve the original motion and background."
    },
    {
      "type": "base_video",
      "url": "https://example.com/source.mp4",
      "id": "video_1"
    }
  ],
  "settings": {
