Kling V3 Omni & Create Element Integration Guide

This guide covers how to use the Kling V3 Omni video generation model and the Kling Create Element model through the request queue API.

​
Overview

ModelModel IDPurpose
Kling V3 Omnikling-v3-omniUnified video generation: text-to-video, image-to-video, video editing, multi-shot storyboards, element-driven generation
Kling Create Elementkling-create-elementCreate reusable character/object elements from images or videos for consistent appearances across generations
These two models work together: create elements with kling-create-element, then reference them in kling-v3-omni video generation using element_id and the <<<element_1>>> prompt syntax.

​
Kling V3 Omni (kling-v3-omni)

​
Capabilities

  • Text-to-Video: Generate videos purely from text prompts
  • Image-to-Video: Use start frame and/or end frame images to guide generation
  • Video Editing: Edit an existing video (refer_type: "base")
  • Feature Reference: Use a video as a style/motion reference (refer_type: "feature")
  • Element-Driven: Reference custom elements for consistent characters/objects
  • Multi-Shot Storyboards: Create multi-shot videos with per-shot prompts and durations
  • Native Audio: Optional simultaneous audio generation (sound: "on")

​
Parameters

​
Core Parameters

ParameterTypeRequiredDefaultDescription
promptstringConditional-Text prompt (max 2500 chars). Supports <<<element_1>>>, <<<image_1>>>, <<<video_1>>> references. Required when multi_shot is false.
modeenumNo"pro""std" (720P, cost-effective) or "pro" (1080P, higher quality)
durationstringNo"5"Video length in seconds: "3" through "15". Ignored when using video editing (refer_type: "base").

​
Image & Video Input Parameters (JSON type)

image_list (json, optional)
Reference image list. Images can serve as start/end frames or as element/scene/style references. Types: "first_frame", "end_frame". End frame requires a first frame. Formats: .jpg/.jpeg/.png, max 10MB, min 300px, aspect ratio 1:2.5–2.5:1. 
"image_list": [
    {
        "image_url": "https://storage.example.com/start.jpg",
        "type": "first_frame"
    },
    {
        "image_url": "https://storage.example.com/end.jpg",
        "type": "end_frame"
    }
]
video_list (json, optional)
Reference video. refer_type: "base" (video editing) or "feature" (style/motion reference). keep_original_sound: "yes" or "no". When video_list is provided, sound must be "off". Formats: .mp4/.mov, 3–10s, 720–2160px, 24–60fps, max 200MB. 
"video_list": [

    {
        "element_id": "123456"
    }
]
Mode 2. Inline image elements (auto-created): Provide frontal_image and refer_images directly. The system auto-creates the element via the Create Element API before generating the video. 
"element_list": [
    {
        "frontal_image": "https://storage.example.com/front.jpg",
        "refer_images": [

                "refer_images": [
                    "https://storage.example.com/character-side.jpg",
                    "https://storage.example.com/character-back.jpg"
                ]
            }
        ]
    }
}

​
14. Inline Video Element (Auto-Created)

Provide a video reference directly to auto-create a video character element. 
{
    "model": "kling-v3-omni",
    "payload": {
        "prompt": "<<<element_1>>> giving a speech on stage",
        "mode": "pro",
        "duration": "8",
        "aspect_ratio": "16:9",
        "sound": "on",
        "element_list": [
            {
                "element_name": "Speaker",
                "refer_videos": [
                    "https://storage.example.com/speaker-clip.mp4"
                ]
            }
        ]
    }
}

​
15. Mixed Existing and Inline Elements

{
    "model": "kling-v3-omni",
    "payload": {
        "prompt": "<<<element_1>>> and <<<element_2>>> meeting at a train station",
        "mode": "pro",
        "duration": "10",
        "aspect_ratio": "16:9",
        "sound": "off",
        "element_list": [
            {
                "element_id": "123456"
            },
            {
                "frontal_image": "https://storage.example.com/new-character-front.jpg",
                "refer_images": [
                    "https://storage.example.com/new-character-side.jpg"
                ]
            }
        ]
    }
}

{
    "model": "kling-create-element",
    "payload": {
        "element_name": "Chef Maria",
        "element_description": "Female chef with a white hat and apron, warm smile",

            "https://storage.example.com/maria-cooking.jpg",
            "https://storage.example.com/maria-profile.jpg"
        ],
        "tag_list": [
            {
                "tag_id": "o_102"
            }
        ]
    }
}
Response: 
{
    "request_id": "abc-123",
    "model": "kling-create-element",
    "status": "dispatched",
    "created_at": 1740000000
}

​
Step 2: Wait for element creation to complete

Poll GET /requests/abc-123 until status is "success". The outcome will contain the created element with its element_id.

​
Step 3: Use the element in V3 Omni video generation

POST /requests

{
    "model": "kling-v3-omni",
    "payload": {
        "prompt": "<<<element_1>>> cooking pasta in a rustic Italian kitchen, steam rising from the pot, warm lighting",
        "mode": "pro",
        "duration": "8",
        "aspect_ratio": "16:9",
        "sound": "on",
        "element_list": [
            {
                "element_id": "987654"
            }
        ]
    }
}

​
Step 4: Retrieve the generated video

Poll GET /requests/{request_id} until status is "success". The outcome will contain: 
{
    "media_urls": [
        {
            "id": "0",
            "url": "https://..."
        }
    ],
    "thumbnail_image_url": "https://..."
}
