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"` `"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"` `"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".

Outputs
