Body Parameters

Parameter	Type	Definition
duration	`integer`	Duration of the video in seconds. Set to `3`, `4`, `5`, `6`, `7`, `8`, `9`, `10`, `11`, `12`, `13`, `14`, or `15`. Defaults to `5`.
guidances.start_frame	`array`	Maximum 1 item. Each item includes image.id and image.type (`INIT`, `GENERATION`, `UPLOADED`, `GENERATED`, or `VARIATION`). Use a reference image to seed the video.
height	`integer`	Sets the height of the output video in pixels. See the Dimensions table for valid values.
mode	`string`	Deprecated. Width and height are the canonical inputs for this model; this field is retained for backwards compatibility. `RESOLUTION_720` routes to the standard (720p) tier, `RESOLUTION_1080` routes to the pro (1080p) tier. Defaults to `RESOLUTION_1080`.
model	`string`	Specifies the model used for generation. Set to `kling-3.0-turbo`.
motion_has_audio	`boolean`	Whether the video generation will include audio. Defaults to `true`.
prompt	`string`	Text description of the video content to generate. Maximum of 2500 characters.
public	`boolean`	Controls whether the generated video is public (true) or private (false).
quantity	`integer`	The number of outputs to generate. Minimum `1`, maximum `1`. Defaults to `1`.
width	`integer`	Sets the width of the output video in pixels. See the Dimensions table for valid values.

Dimensions

The API accepts width and height parameters in the following aspect ratio combinations:

Resolution	Aspect Ratio	Pixel Values (Width x Height)
720p	16:9 (Landscape)	1280x720
	1:1 (Square)	960x960
	9:16 (Portrait)	720x1280
1080p	16:9 (Landscape)	1920x1080
	1:1 (Square)	1440x1440
	9:16 (Portrait)	1080x1920
Auto	Model-selected	0x0
