Kling 4.0 Text to Video - ComfyUI Built-in Node Documentation - ComfyUI

Generates a video from a text prompt with the Kling 4.0 model, including audio. This node sends the prompt and the generation settings to the Kling API, waits for the task to finish, and returns the finished video. Use it when a clip has to be created from a description alone, with no reference media.
