# Runway Partner Nodes Video Generation ComfyUI Official Example

> This article will introduce how to use Runway nodes in ComfyUI for video generation workflows

Runway is a company focused on generative AI, providing powerful video generation capabilities. Currently, ComfyUI has integrated the Runway API, allowing you to directly use the related nodes in ComfyUI for video generation.

Currently, ComfyUI natively integrates the following Runway video generation model:

* Runway Gen4 turbo

<Warning>
  **End of life (EOL)**: **Runway Gen3a Turbo** and **Runway First-Last-Frame to Video** reached end of life on **July 30, 2026**. Runway retired Gen-3 Alpha Turbo on that date. The related Partner Nodes (`RunwayImageToVideoNodeGen3a`, `RunwayFirstLastFrameNode`) and workflow templates are deprecated and no longer supported.
</Warning>

## What Runway Video Generation is good at

* **Image-to-video generation**: The `Runway Gen4 turbo` node generates a video from an input image and a text prompt describing the video content
* **Adjustable video length**: Modify the `duration` parameter to set the video length
* **Adjustable aspect ratio**: Modify the `ratio` parameter to set the video aspect ratio

## Use it in ComfyUI
