## Resolution and Aspect Ratio Combinations

| Resolution | Supported Aspect Ratios         | Notes                   |
| ---------- | ------------------------------- | ----------------------- |
| 480p       | 16:9, 4:3, 1:1, 3:4, 9:16, 21:9 | All supported           |

<ParamField body="image_urls" type="string[]">
  Compatibility image URL array for first/last-frame image-to-video generation

  Compatibility rules:

  * 1 image: treated as `first_frame`
  * 2 images: treated as `first_frame` and `last_frame`
  * More than 2 images: only the first two are used

  We recommend using `image_with_roles` to explicitly specify first and last frames

  Example: `["https://example.com/first.png", "https://example.com/last.png"]`

  `image_urls` and `image_with_roles` cannot be used together
</ParamField>

<ParamField body="image_with_roles" type="array">

    </ParamField>

    <ParamField body="role" type="string" required>
      Image role

      Options:

      * `first_frame` - First frame image, used as the starting frame (only one supported)
      * `last_frame` - Last frame image, used as the ending frame (only one supported)
    </ParamField>
  </Expandable>

  Example:

  ```json theme={null}
  [
    {"url": "https://example.com/first.png", "role": "first_frame"},
    {"url": "https://example.com/last.png", "role": "last_frame"}
  ]
  ```

  <Warning>
    * `image_urls` and `image_with_roles` cannot be used together
