# LumaRay32VideoReframeNode - ComfyUI Built-in Node Documentation

> Complete documentation for the LumaRay32VideoReframeNode node in ComfyUI. Learn its inputs, outputs, parameters and usage.

This node changes the aspect ratio of an existing video using Luma Ray 3.2, which fills the newly exposed canvas areas with generated content. The source video can be up to 30 seconds long, and billing is per second of output.

## Inputs

| Parameter      | Description                                                       | Data Type | Required | Range                                                           |
| -------------- | ----------------------------------------------------------------- | --------- | -------- | --------------------------------------------------------------- |
| `video`        | Source video to reframe. Up to 30 seconds.                        | VIDEO     | Yes      | -                                                               |
| `prompt`       | Describes how the newly exposed canvas areas should be filled.    | STRING    | Yes      | Min length: 1 character<br />Max length: 6000 characters        |
| `aspect_ratio` | The target aspect ratio for the reframed video (default: "16:9"). | STRING    | Yes      | "16:9"<br />"9:16"<br />"1:1"<br />"4:3"<br />"3:4"<br />"21:9" |
| `resolution`   | The output resolution of the reframed video (default: "720p").    | STRING    | Yes      | "360p"<br />"540p"<br />"720p"<br />"1080p"                     |
| `seed`         | Seed for reproducible generation.                                 | INT       | Yes      | -                                                               |

**Note:** The `1080p` resolution is not available for vertical aspect ratios (`9:16` and `3:4`) when reframing.

## Outputs

| Output Name     | Description                                                           | Data Type |
| --------------- | --------------------------------------------------------------------- | --------- |
| `video`         | The reframed video with the new aspect ratio and filled canvas areas. | VIDEO     |
| `generation_id` | The unique identifier for the generation request.                     | STRING    |
