The Omni model can achieve various capabilities through Prompt with elements, images, videos, and other content.

Request Header

Content-TypestringRequiredDefault to application/json

Data Exchange Format

AuthorizationstringRequired

Authentication information, refer to API authentication

Request Body

model_namestringOptionalDefault to kling-video-o1

Model Name

Enum values：kling-video-o1kling-v3-omni

multi_shotbooleanOptionalDefault to false

Whether to generate multi-shot video.

When true: the prompt parameter is invalid, and it does not support setting the start & end frames to generate videos

When false: the shot_type and multi_prompt parameters are invalid.

shot_typestringOptional

Storyboard method.

Enum values：customizeintelligence

When multi_shot is true, this parameter is required.

promptstringOptional

Text prompt words, which can include positive and negative descriptions.

The prompt words can be templated to meet different video generation needs

Must not exceed 2,500 characters

When the "multi_shot" parameter is set to false or when the "multi_shot" parameter is set to true and the "shot-type" parameter is set to intelligence, the current parameter must not be empty.

💡

The Omni model can achieve various capabilities through Prompt with elements, images, videos, and other content:

Specify elements/images/videos using <<<>>> format, e.g.: <<<element_1>>>, <<<image_1>>>, <<<video_1>>>
For detailed capabilities, see: KLING Omni Model User Guide, Kling VIDEO 3.0 Omni Model User Guide

The support range for different model versions and video modes varies. For details, see Capability Map

multi_promptarrayOptional

Information about each storyboard, such as prompts and duration.

Define shot sequence number, corresponding prompt and duration via index, prompt, and duration parameters.

Supports up to 6 storyboards, minimum 1.
Max length per storyboard content: 512.
Each storyboard duration must not exceed total task duration and must be ≥ 1.
Sum of all storyboard durations must equal total task duration.

When multi_shot is true and shot_type is customize, this parameter is required. Format:

"multi_prompt":[
  { "index": int, "prompt": "string", "duration": "5" },
  { "index": int, "prompt": "string", "duration": "5" }
]

image_listarrayOptional

Reference Image List, including element, scene, style reference images.

Including reference images of the element, scene, style, etc., it can also be used as the start or end frame to generate videos; When generating a video as the start or end frame:
- Define whether the image is in the first and last frames using the type parameter: first_frame is the start frame, end_frame is the end frame.
  - Currently does not support only the end frame, which means that when there is a end frame image, there must be a first frame image.
  - If the image is not the start & end frame, do not configure the type parameter.
- When generating a video using the first frame or the first and last frames, video editing functions cannot be used.

Load with key:value, details as follows:

"image_list":[
  { "image_url": "image_url"},
  { "image_url": "image_url" }
]

Image Requirements:

Supports Base64 encoding or image URL (ensure accessibility)
Formats: .jpg / .jpeg / .png
File size: ≤10MB
Dimensions: min 300px, aspect ratio 1:2.5 ~ 2.5:1

Quantity Limits:

When there are reference video, the sum of the amount of reference image and the amount of reference element shall not exceed 4.
When there is no reference video, the sum of the amount of reference image and the amount of reference element shall not exceed 7.
When using the O1 model, setting the start & end frame is not supported when there are more than two images in the array.

image_url parameter value must not be empty

When generating a video using the first frame, a maximum of 3 elements are supported.
When generating videos using the start & end frames, the kling-v3-omni model supports up to 3 elements, while the kling-video-o1 model does not support 1 element.
When there is a reference video, the sum of the number of reference images and the number of reference subjects must not exceed 4, and the use of video subjects is not supported.
When there is no reference video, the sum of the number of reference images and the number of reference subjects must not exceed 7.

Elements are categorized into video character elements and Multi-Image Elements, with different scopes. See Kling Element Library User Guide.

Load with key:value format as follows:

This parameter is required when NOT using first-frame reference or video editing function.

durationstringOptionalDefault to 5

Video duration in seconds

Enum values：3456789101112131415

When using the video editing function ("refer_type": "base"), the output result is the same as the duration of the incoming video, and the current parameter is invalid. Calculate billing by rounding the input video duration to the nearest integer.

The support range for different model versions and video modes varies. For details, see Capability Map

watermark_infoobjectOptional

Whether to generate watermarked results simultaneously

Defined by the enabled parameter, format:

  "watermark_info": { "enabled": boolean }

FAQ

1、 Video Duration Support

Text-to-video and image-to-video (NOT including first/last frame): Optional duration of 3~10s.
When video input is provided (video_list is not empty) and video editing functionality (type = base) is used: Duration cannot be specified and will align with the input video.
Other cases (when no video is provided but an image + subject is used for video generation, or when a video is provided with video type = feature): Optional duration of 3-10s.

2、 How to Extend a Video?

This can be achieved via “video reference”.
By inputting a video and using a prompt to direct the model to “generate the next shot” or “generate the previous shot”.

curl --location 'https://api-singapore.klingai.com/v1/videos/omni-video' \
--header 'Authorization: Bearer <token>' \
--header 'Content-Type: application/json' \
--data '{
    "model_name": "kling-video-o1",
    "prompt": "Based on <<<video_1>>>, generate the next shot.",
    "video_list": [
      {
        "video_url":"xxxxxxxx",
        "refer_type":"feature",
        "keep_original_sound":"yes"
      }
    ],
    "mode": "pro"
}'

3、 Aspect Ratio Support

Not Supported: Instruction-based transformation (video editing), image-to-video (not including first/last frame).
Supported: Text-to-video, image/subject reference, video reference (other scenarios), video reference (generating next/previous shot).
