# LumaVideoNode - ComfyUI Built-in Node Documentation

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

> This documentation was AI-generated. If you find any errors or have suggestions for improvement, please feel free to contribute! [Edit on GitHub](https://github.com/Comfy-Org/embedded-docs/blob/main/comfyui_embedded_docs/docs/LumaVideoNode/en.md)

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

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