# LTXV Text To Video

The LTXV Text To Video node generates professional-quality videos from a text description. It connects to an external API to create videos with customizable duration, resolution, and frame rate. You can also choose to have AI-generated audio added to the video.

## Inputs

| Parameter | Description | Data Type | Required | Range |
| --- | --- | --- | --- | --- |
| `model` | The AI model to use for video generation. "LTX-2 (Pro)" offers higher quality, while "LTX-2 (Fast)" is optimized for speed. | COMBO | Yes | `"LTX-2 (Pro)"`<br>`"LTX-2 (Fast)"` |
| `prompt` | The text description that the AI will use to generate the video. This field supports multiple lines of text. | STRING | Yes | - |
| `duration` | The length of the generated video in seconds (default: 8). | COMBO | Yes | `6`<br>`8`<br>`10`<br>`12`<br>`14`<br>`16`<br>`18`<br>`20` |
| `resolution` | The pixel dimensions (width x height) of the output video. | COMBO | Yes | `"1920x1080"`<br>`"2560x1440"`<br>`"3840x2160"` |
| `fps` | The frames per second for the video (default: 25). | COMBO | Yes | `25`<br>`50` |
| `generate_audio` | When enabled, the generated video will include AI-generated audio matching the scene (default: False). | BOOLEAN | No | - |

**Important Constraints:**

* The `prompt` must be between 1 and 10,000 characters long.
* If you select a `duration` greater than 10 seconds, you must also use the `"LTX-2 (Fast)"` model, a resolution of `"1920x1080"`, and an `fps` of `25`. This combination is required for longer videos.

## Outputs

| Output Name | Description | Data Type |
| --- | --- | --- |
| `output` | The generated video file. | VIDEO |
