The Vidu Q3 Text-to-Video Generation node creates a video from a text description. It uses the Vidu Q3 Pro model to generate video content based on your prompt, allowing you to control the video's length, resolution, and aspect ratio.

## Inputs

| Parameter            | Data Type | Required | Range                                                         | Description                                                                                                                                              |
| -------------------- | --------- | -------- | ------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `model`              | COMBO     | Yes      | `"viduq3-pro"`                                                | Model to use for video generation. Selecting this option reveals additional configuration parameters for aspect ratio, resolution, duration, and audio.  |
| `model.aspect_ratio` | COMBO     | Yes\*    | `"16:9"`<br />`"9:16"`<br />`"3:4"`<br />`"4:3"`<br />`"1:1"` | The aspect ratio of the output video. This parameter is revealed when the `model` is selected.                                                           |
| `model.resolution`   | COMBO     | Yes\*    | `"720p"`<br />`"1080p"`                                       | Resolution of the output video. This parameter is revealed when the `model` is selected.                                                                 |
| `model.duration`     | INT       | Yes\*    | 1 to 16                                                       | Duration of the output video in seconds (default: 5). This parameter is revealed when the `model` is selected.                                           |
| `model.audio`        | BOOLEAN   | Yes\*    | True/False                                                    | When enabled, outputs video with sound (including dialogue and sound effects) (default: False). This parameter is revealed when the `model` is selected. |
| `prompt`             | STRING    | Yes      | N/A                                                           | A textual description for video generation, with a maximum length of 2000 characters.                                                                    |
| `seed`               | INT       | No       | 0 to 2147483647                                               | A seed value for controlling the randomness of the generation (default: 1).                                                                              |

\*Note: The parameters `aspect_ratio`, `resolution`, `duration`, and `audio` are required once the `model` is selected, as they are part of its configuration.

## Outputs

| Output Name | Data Type | Description               |
