Reference 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.
Reference 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'.
Whether to keep the original sound from the reference video.
Controls 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). Allowed values: image, video.

It gives teams a concrete way to decide whether the endpoint fits the available asset and desired change while keeping technical parameter details in the specifications below.

Highlights

  • Model capability. Within the kling-video/v3/standard/motion-control endpoint, kwaivgi/kling-video/v3/standard/motion-control documents visual effects to existing videos with natural language instructions.
  • Core workflow. Within the kling-video/v3/standard/motion-control endpoint, kwaivgi/kling-video/v3/standard/motion-control documents video to video.
  • Creative control. Within the kling-video/v3/standard/motion-control endpoint, kwaivgi/kling-video/v3/standard/motion-control documents controls 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).
  • Source guidance. Within the kling-video/v3/standard/motion-control endpoint, kwaivgi/kling-video/v3/standard/motion-control documents reference 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.

Pricing

  • Local price formula: (usage.duration ?? (media_length(params.video ?? 0) > 0 ? media_length(params.video) : 5)) * 0.126
