print(result)

Input Schema

prompt

string

image_url

string

required

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.

video_url

string

required

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’.

keep_original_sound

boolean

default:"true"

Whether to keep the original sound from the reference video. Default value: true

character_orientation

CharacterOrientationEnum

required

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).Possible values: image, video

elements

list<KlingV3ImageElementInput>

Optional element for facial consistency binding. Upload a facial element to enhance identity preservation in the generated video. Only 1 element is supported. Reference in prompt as @Element1. Element binding is only supported when character_orientation is ‘video’.

Output Schema

video

File

required

The generated video

Input Example

{
  "prompt": "A man dancing",
  "image_url": "https://v3b.fal.media/files/b/0a90ffa7/TNErq9yD7ZxGRATjfAqnh_EIgJSN67.png",
