# KlingImage2VideoNode - ComfyUI Built-in Node Documentation

> Complete documentation for the KlingImage2VideoNode node in ComfyUI. Learn its inputs, outputs, parameters and usage.

The Kling Image to Video Node generates a video from a starting reference image using text prompts. It takes an image as the first frame and creates a video sequence based on positive and negative text descriptions, with configurable options for model, duration, aspect ratio, and generation mode.

## Inputs
