# KlingTextToVideoNode - ComfyUI Built-in Node Documentation

> The Kling Text to Video node generates videos from text descriptions using the Kling video generation API.

The Kling Text to Video node generates videos from text descriptions using the Kling video generation API. It sends the prompt and settings (aspect ratio, generation mode, and CFG scale) to the API, waits for the generation task to complete, and then returns the resulting video along with its ID and duration.

## Inputs
