Kling v3.0 Standard Image-to-Video transforms static images into dynamic videos with natural motion, smooth scene dynamics, optional audio co-generation, and multi-prompt composition support.

This is an asynchronous API; only the task_id will be returned. You should use the task_id to request the [Task Result API](/docs/api-reference/model-apis-task-result) to retrieve the video generation results.

##

[​](#request-headers)

Request Headers

[​](#param-content-type)

Content-Type

string

required

Supports: `application/json`

[​](#param-authorization)

Authorization

string

required

Bearer authentication format, for example: Bearer {{API Key}}.

##

[​](#request-body)

Request Body

[​](#param-image)

image

string

required

First frame image for video; supports `.jpg`, `.jpeg`, `.png`.
Image file size must not exceed 10MB; width and height must be >= 300px; aspect ratio must be between 1:2.5 and 2.5:1.

[​](#param-sound)

sound

boolean

default:false

Whether to generate audio simultaneously when generating video.

[​](#param-prompt)

prompt

string

required

Positive prompt text for video generation, describing scene motion, camera moves, actions, voice style, ambience, and sound effects; must not exceed 2500 characters.

[​](#param-duration)

duration

integer

default:5

Duration of generated video in seconds (3-15).Optional values: `3`, `4`, `5`, `6`, `7`, `8`, `9`, `10`, `11`, `12`, `13`, `14`, `15`

[​](#param-cfg-scale)

cfg_scale

number

Controls the flexibility of video generation. Lower values produce more natural motion; higher values result in generated content more closely following the prompt.Value range: [0, 1]

[​](#param-end-image)

end_image

string

Ending frame image URL for guided transitions between start and end frames. Same format constraints as image. Cannot be used together with multi_prompt.

[​](#param-multi-prompt)

multi_prompt

object[]

Array of prompts for multi-shot video composition. Each item contains a prompt and duration for one segment. Cannot be used together with end_image.

Hide properties

[​](#param-prompt-1)

prompt

string

required

Motion description for this video segment.

[​](#param-duration-1)

duration

integer

default:5

Duration of this segment in seconds (3-15).Value range: [3, 15]

[​](#param-negative-prompt)

negative_prompt

string

Negative prompt specifying elements to avoid in visuals and audio; must not exceed 2500 characters.

##

[​](#response)

Response

[​](#param-task-id)

task_id

string

required

Use the task_id to request the [Task Result API](/docs/api-reference/model-apis-task-result) to retrieve the generated outputs.
