The Pika Swaps node allows you to replace objects or regions in your video with new images. You can define the areas to replace using either a mask or coordinates, and the node will seamlessly swap the specified content throughout the video sequence.

## Inputs

| Parameter         | Data Type | Required | Range           | Description                                               |
| ----------------- | --------- | -------- | --------------- | --------------------------------------------------------- |
| `video`           | VIDEO     | Yes      | -               | The video to swap an object in.                           |
| `image`           | IMAGE     | Yes      | -               | The image used to replace the masked object in the video. |
| `mask`            | MASK      | Yes      | -               | Use the mask to define areas in the video to replace.     |
| `prompt_text`     | STRING    | Yes      | -               | Text prompt describing the desired replacement.           |
| `negative_prompt` | STRING    | Yes      | -               | Text prompt describing what to avoid in the replacement.  |
| `seed`            | INT       | Yes      | 0 to 4294967295 | Random seed value for consistent results.                 |

**Note:** This node requires all input parameters to be provided. The `video`, `image`, and `mask` work together to define the replacement operation, where the mask specifies which areas of the video will be replaced with the provided image.
