# LumaVideoNode - ComfyUI Built-in Node Documentation

> Generates videos synchronously based on a text prompt and output settings.

Generates videos synchronously based on a text prompt and output settings. This node creates video content using text descriptions and various generation parameters, producing the final video output once the generation process is complete.

## Inputs

| Parameter | Description | Data Type | Required | Range |
| - | - | - | - | - |
| `prompt` | Prompt for the video generation (default: empty string). Must be at least 3 characters long. | STRING | Yes | - |
| `model` | The video generation model to use. | COMBO | Yes | `"ray_1_6"`<br />`"ray_2"` |
| `aspect_ratio` | The aspect ratio for the generated video (default: "16:9"). | COMBO | Yes | `"16:9"`<br />`"9:16"`<br />`"1:1"`<br />`"4:3"`<br />`"3:4"`<br />`"21:9"`<br />`"9:21"` |
| `resolution` | The output resolution for the video (default: "540p"). This parameter is ignored when using the `ray_1_6` model. | COMBO | Yes | `"540p"`<br />`"720p"`<br />`"1080p"` |
| `duration` | The duration of the generated video. This parameter is ignored when using the `ray_1_6` model. | COMBO | Yes | `"5s"`<br />`"9s"` |
| `loop` | Whether the video should loop (default: False). | BOOLEAN | Yes | - |
| `seed` | Seed to determine if node should re-run; actual results are nondeterministic regardless of seed (default: 0). | INT | Yes | 0 to 18446744073709551615 |
| `luma_concepts` | Optional Camera Concepts to dictate camera motion via the Luma Concepts node. | CUSTOM | No | - |

**Note:** When using the `ray_1_6` model, the `duration` and `resolution` parameters are automatically ignored and do not affect the generation.

## Outputs

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