# KlingTextToVideoWithAudio - ComfyUI Built-in Node Documentation

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

The Kling Text to Video with Audio node generates a short video from a text description. It sends a request to the Kling AI service, which processes the prompt and returns a video file. The node can also generate accompanying audio for the video based on the text.
