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

| Parameter         | Data Type | Required | Range                                                                                                                                                                        | Description                                                                                                                                                                                                                 |
