Body Parameters

Parameter	Type	Definition
duration	`number`	Length of the generated video in seconds. Set to `2`, `3`, `4`, `5`, `6`, `7`, `8`, `9`, or `10`. Defaults to `5`.
guidances.end_frame	`array`	Maximum 1 item. Each item includes image.id and image.type (`GENERATED` or `UPLOADED`).
guidances.image_reference	`array`	Reference images to guide the video generation. Each item includes image.id, image.type (`GENERATED` or `UPLOADED`), and strength (`LOW`, `MID`, or `HIGH`; defaults to `MID`).
guidances.start_frame	`array`	Maximum 1 item. Each item includes image.id and image.type (`GENERATED` or `UPLOADED`).
guidances.video_reference_base	`array`	Maximum 1 item. Base video to be edited. Each item includes a `video` object with `id` and `type` (`UPLOADED` or `GENERATED`), and an optional item-level `type` (`BASE` or `FEATURE`): `BASE` routes to edit-video, `FEATURE` routes to reference-to-video.
height	`number`	Sets the height of the output video in pixels.
model	`string`	Specifies the model used for generation. Set to `wan-2.7`.
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	`number`	Number of outputs to generate. Defaults to `1` (maximum `1`).
resolution	`string`	Output resolution for edit mode. Set to `720p` or `1080p`. Defaults to `1080p`.
width	`number`	Sets the width of the output video in pixels.

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
