# Luma Text to Video API Node ComfyUI Official Guide

> Learn how to use the Luma Text to Video API node in ComfyUI

The [Luma Text to Video](/built-in-nodes/api-node/video/luma/luma-text-to-video) node allows you to create high-quality, smooth videos from text descriptions using Luma AI's innovative video generation technology.

In this guide, we'll show you how to set up a text-to-video workflow using this node.

<Tip>
  To use the API nodes, you need to ensure that you are logged in properly and using a permitted network environment. Please refer to the [API Nodes Overview](/tutorials/api-nodes/overview) section of the documentation to understand the specific requirements for using the API nodes.
</Tip>

<Tip>
  Make sure your ComfyUI is updated.

  * [Download ComfyUI](https://www.comfy.org/download)
  * [Update Guide](/installation/update_comfyui)

  Workflows in this guide can be found in the [Workflow Templates](/interface/features/template).
  If you can't find them in the template, your ComfyUI may be outdated.(Desktop version's update will delay sometime)

  If nodes are missing when loading a workflow, possible reasons:

  1. Not using the latest ComfyUI version(Nightly version)
  2. Using Stable or Desktop version (Latest changes may not be included)
  3. Some nodes failed to import at startup

## Text to Video Workflow with Luma API Node

The Luma Text to Video node requires text prompts to describe the video content. In this guide, we've created examples using `prompt` and `luma_concepts` to showcase Luma AI's excellent video generation capabilities.

### 1. Download the Workflow

The workflow information is included in the metadata of the video below. Download and drag it into ComfyUI to load the workflow.

### 2. Follow the Steps

Follow these basic steps to run the workflow:

1. Write your prompt in the `Luma Text to Video` node to describe the video content you want
2. Click the `Run` button or use the shortcut `Ctrl(cmd) + Enter` to generate the video
3. After the API returns results, you can view the generated video in the `Save Video` node. The video will also be saved to the `ComfyUI/output/` directory

> (Optional) Modify the `Luma Concepts` node to control camera movements and add professional cinematography

### 3. Additional Notes

* **Writing Prompts**: Describe scenes, subjects, actions, and mood in detail for best results
* **Luma Concepts**: Mainly used for camera control to create professional video shots
* **Seed Parameter**: Only determines if the node should rerun, doesn't affect generation results
* **Model Selection**: Different video models have different features, adjustable via the model parameter
* **Resolution and Duration**: Adjust output video resolution and length using these parameters
* **Ray 1.6 Model Note**: Duration and resolution parameters don't work when using the Ray 1.6 model
