The PixVerse Text to Video node connects to PixVerse's text-to-video API, allowing users to generate high-quality videos from text descriptions. Users can customize their creations by adjusting various parameters like video quality, duration, and motion mode.

## Parameters

### Required Parameters

| Parameter         | Type    | Default                   | Description                                   |
| ----------------- | ------- | ------------------------- | --------------------------------------------- |
| prompt            | string  | ""                        | Text prompt describing the video content      |
| aspect\_ratio     | select  | -                         | Output video aspect ratio                     |
| quality           | select  | PixverseQuality.res\_540p | Video quality level                           |
| duration\_seconds | select  | -                         | Video duration                                |
| motion\_mode      | select  | -                         | Video motion mode                             |
| seed              | integer | 0                         | Random seed for consistent generation results |

### Optional Parameters

| Parameter          | Type               | Default | Description                          |
| ------------------ | ------------------ | ------- | ------------------------------------ |
| negative\_prompt   | string             | ""      | Elements to exclude from the video   |
| pixverse\_template | PIXVERSE\_TEMPLATE | None    | Optional template for style settings |

### Limitations

* 1080p quality only supports normal motion mode with 5-second duration
* Non 5-second durations only support normal motion mode

### Output

| Output | Type  | Description     |
| ------ | ----- | --------------- |
| VIDEO  | video | Generated video |
