# KlingMotionControl - ComfyUI Built-in Node Documentation

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

> This documentation was AI-generated. If you find any errors or have suggestions for improvement, please feel free to contribute! [Edit on GitHub](https://github.com/Comfy-Org/embedded-docs/blob/main/comfyui_embedded_docs/docs/KlingMotionControl/en.md)

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               | Data Type | Required | Range                    | Description                                                                                                                                                                                                                                                                                          |
| ----------------------- | --------- | -------- | ------------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `prompt`                | STRING    | Yes      | N/A                      | A text description of the desired video. Maximum length is 2500 characters.                                                                                                                                                                                                                          |
| `reference_image`       | IMAGE     | Yes      | N/A                      | 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.                                                                                                                                                                       |
| `reference_video`       | VIDEO     | Yes      | N/A                      | A motion reference video used to drive the character's movement and expression. Minimum dimensions are 340x340 pixels, maximum dimensions are 3850x3850 pixels. Duration limits depend on the `character_orientation` setting.                                                                       |
| `keep_original_sound`   | BOOLEAN   | No       | N/A                      | Determines if the original audio from the reference video is kept in the output. Default is `True`.                                                                                                                                                                                                  |
| `character_orientation` | COMBO     | No       | `"video"`<br />`"image"` | Controls where the character's facing/orientation comes from. `"video"`: movements, expressions, camera moves, and orientation follow the motion reference video. `"image"`: movements and expressions follow the motion reference video, but the character orientation matches the reference image. |
| `mode`                  | COMBO     | No       | `"pro"`<br />`"std"`     | The generation mode to use.                                                                                                                                                                                                                                                                          |

**Constraints:**

* The `reference_video` duration must be between 3 and 30 seconds when `character_orientation` is set to `"video"`.
* The `reference_video` duration must be between 3 and 10 seconds when `character_orientation` is set to `"image"`.
