Input resources for the task (images, audio, etc). These must be nested inside the \`inputs\` object.

### [referenceImages](https://runware.ai/docs/models/klingai-video-o3-pro#request-inputs-referenceimages)

- **Path**: `inputs.referenceImages`
- **Type**: `array of strings`

List of reference images (UUID, URL, Data URI, or Base64).

### [frameImages](https://runware.ai/docs/models/klingai-video-o3-pro#request-inputs-frameimages)

- **Path**: `inputs.frameImages`
- **Type**: `array of objects (2 properties)`

An array of objects that define key frames to guide video generation. Each object specifies an input image and optionally its position within the video timeline.

The `frameImages` parameter allows you to constrain specific frames within the video sequence, ensuring that particular visual content appears at designated points. This is different from `referenceImages`, which provide overall visual guidance without constraining specific timeline positions.

When the `frame` parameter is omitted from objects, automatic distribution rules apply:

- **1 image**: Used as the first frame.
- **2 images**: First and last frames.

**Examples**:

**Single frame (automatic positioning):** When only one image is provided, it automatically becomes the first frame of the video.

```json
"frameImages": [
  {
    "image": "aac49721-1964-481a-ae78-8a4e29b91402"
  }
]
```

**First and last frames:** With two images, they automatically become the first and last frames of the video sequence.

```json
"frameImages": [
  {
    "image": "aac49721-1964-481a-ae78-8a4e29b91402",
    "frame": "first"
  },
  {
    "image": "3ad204c3-a9de-4963-8a1a-c3911e3afafe",

  "positivePrompt": "A cinematic scene in a rotating orbital greenhouse ring at dawn. Begin from the supplied first frame and animate it into a serene, high-detail sequence: a young dancer slowly performs a weightless-inspired contemporary routine on a circular brass platform while the camera makes a gentle floating arc around her. Hanging vines sway subtly with the station rotation, tiny pollen particles drift through warm peach sunlight, reflections slide across curved glass, and Earth glides majestically beyond the panoramic windows. Preserve the subject's identity and costume, maintain elegant realism, rich environmental detail, soft atmospheric depth, smooth physically plausible motion, stable composition, and natural cinematic audio with faint mechanical hum, quiet footwork, fabric movement, and distant greenhouse ambience.",
