# KlingMotionControl - ComfyUI Built-in Node Documentation

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

The Kling Motion Control node generates a video by applying the motion, expressions, and camera movements from a reference video to a character defined by a reference image and a text prompt. It allows you to control whether the character's final orientation comes from the reference video or the reference image.

## Inputs

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

| `reference_image`       | An image of the character to animate. Minimum dimensions are 340x340 pixels. The aspect ratio must be between 1:2.5 and 2.5:1.                                                                                                                                                                                                                                          | IMAGE     | Yes      | N/A                              |
| `reference_video`       | Motion reference video used to drive movement/expression. Duration limits depend on `character_orientation` setting. Minimum dimensions are 340x340 pixels, maximum dimensions are 3850x3850 pixels.                                                                                                                                                                    | VIDEO     | Yes      | N/A                              |
| `keep_original_sound`   | Determines if the original audio from the reference video is kept in the output. Default is `True`.                                                                                                                                                                                                                                                                     | BOOLEAN   | No       | N/A                              |

| `model`                 | The Kling model version to use. Default is `"kling-v2-6"`.                                                                                                                                                                                                                                                                                                              | COMBO     | No       | `"kling-v3"`<br />`"kling-v2-6"` |
