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 |
| --- | --- | --- | --- | --- |
| `prompt` | A text description of the desired video. Maximum length is 2500 characters. | STRING | Yes | N/A |
| `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` | 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. | 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 |
| `character_orientation` | Controls where the character's facing/orientation comes from. `"video"`: movements, expressions, camera moves, and orientation follow the motion reference video (other details via prompt). `"image"`: movements and expressions still follow the motion reference video, but the character orientation matches the reference image (camera/other details via prompt). | COMBO | No | `"video"`<br>`"image"` |
| `mode` | The generation mode to use. | COMBO | No | `"pro"`<br>`"std"` |
| `model` | The Kling model version to use. Default is `"kling-v2-6"`. | COMBO | No | `"kling-v3"`<br>`"kling-v2-6"` |

**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"`.

## Outputs

| Output Name | Description | Data Type |
| --- | --- | --- |
| `output` | The generated video with the character performing the motion from the reference video. | VIDEO |
