kwaivgi/kling-video/v3/pro/motion-controlKling V3 Pro Motion Control by Kuaishou transfers the motion, expressions, and camera movement of a reference video onto the character in an image, producing a 1080p video up to 30 seconds.

}Kling V3 Pro motion control: make the character in image perform the moves of a reference video, with body, hands, and expression following the source.
| Field | Type | Default | Notes |
|---|---|---|---|
prompt | string | — | Optional scene and style direction. |
image | image URL, required | — | Character to animate. JPEG, PNG, or WebP URL. |
video | video URL, required | — | Reference video that supplies the motion. |
keep_original_sound | boolean | true | Keep the reference video's audio track. |
character_orientation | image / video | — | video follows the reference video's orientation (better for complex moves, up to 30s); image follows the image (better for camera moves, up to 10s). |
You pay $0.168 per second of the reference video. The quote before submission assumes 30 seconds; the final charge uses the measured length.
| Reference video | Price |
|---|---|
| 5s reference | $0.84 |
| 10s reference | $1.68 |
| 30s reference | $5.04 |
Failed runs are not charged.

Use the upload or replace control on supported image fields in the Playground. Video URL fields accept a hosted driving video; they do not imply video-upload support.
imagestringrequiredReference image URL. The characters, backgrounds, and other elements in the generated video are based on this reference image. Characters should have clear body proportions, avoid occlusion, and occupy more than 5% of the image area.
videostringrequiredReference video URL. The character actions in the generated video will be consistent with this reference video. Should contain a realistic style character with entire body or upper body visible, including head, without obstruction. Duration limit depends on character_orientation: 10s max for 'image', 30s max for 'video'.
promptstringkeep_original_soundbooleanWhether to keep the original sound from the reference video.
Default: true
character_orientationstringControls whether the output character's orientation matches the reference image or video. 'video': orientation matches reference video - better for complex motions (max 30s). 'image': orientation matches reference image - better for following camera movements (max 10s).
