Workflows
1. Text-to-Video
POST /kling/videos
{
"action": "text2video",
"prompt": "a futuristic city with flying cars",
"model": "kling-v3",
"mode": "std",
"duration": 5,
"aspect_ratio": "16:9"
}
2. Image-to-Video
Animate a still image. Optionally specify an ending frame.
POST /kling/videos
{
"action": "image2video",
"prompt": "the scene slowly comes alive with movement",
"start_image_url": "https://example.com/scene.jpg",
"end_image_url": "https://example.com/end-scene.jpg",
"model": "kling-v3",
"mode": "pro"
}
3. Omni References
Use kling-o1 or kling-v3-omni with reference images and/or one reference video. Cite each item in the prompt using its one-based token.
POST /kling/videos
{
"action": "text2video",
"prompt": "turn <<<video_1>>> into hand-painted animation while preserving its motion",
"model": "kling-o1",
"mode": "std",
"duration": 5,
"video_list": [
{
"video_url": "https://example.com/source.mp4",
"refer_type": "base",
"keep_original_sound": "no"
}
]
}
Use refer_type: "feature" to reference style, motion, or a neighboring shot. Use refer_type: "base" to edit the supplied video. A base video cannot be combined with first/end frames.
4. Extend Video
Continue an existing video with additional seconds.
POST /kling/videos
{
"action": "extend",
"video_id": "existing-video-id",
"prompt": "the camera pulls back to reveal the full landscape",
"model": "kling-v2-5-turbo"
}
5. Motion Control
Apply precise camera/motion control from an image + reference video.
POST /kling/motion
{
"image_url": "https://example.com/subject.jpg",
"video_url": "https://example.com/motion-reference.mp4",
"mode": "std",
"character_orientation": "image"
}
6. Lip Sync
Create a lip-synced video from a source video plus either an audio track or input text.
POST /kling/lip-sync
{
"video_url": "https://example.com/source.mp4",
"mode": "audio2video",
"audio_url": "https://example.com/voiceover.mp3"
}
7. Talking Photo
Animate a still portrait from an image plus an audio track.
POST /kling/talking-photo
{
"image_url": "https://example.com/portrait.jpg",
"audio_url": "https://example.com/voiceover.mp3",
"model": "kling-v2-1-master",
"duration": 5,
"mode": "pro"
}
