Input Schema

11 parameters · 2 required · 9 optional

Parameter	Type	Required	Description
`image`	string	Required	URL of the image used as the first frame of the video. Provide either image_url (optionally with end_image_url) or keyframes — the two anchoring modes are mutually exclusive. · Min length: 1
`prompt`	string	Required	Text prompt describing the motion/scene to generate. · Min length: 1 · Max length: 6000
`hdr`	boolean	Optional	Generate an HDR-encoded MP4. Requires HDR access on the account and a resolution of 720p or 1080p; not supported with loop. · Default: false
`loop`	boolean	Optional	Generate a seamless loop. Only valid for standard-dynamic-range generations without an end frame or keyframes. · Default: false
`duration`	integer	Optional	Duration of the generated video. 10s requires multi-keyframe input (keyframes / keyframe_indexes); it is not supported with a single image_url / end_image_url anchor. · Options: · Default: "5s"
`end_image`	string	Optional	Optional URL of an image used as the last frame. When set, the model interpolates between image_url and end_image_url. Cannot be combined with keyframes.
`keyframes`	string[]	Optional	Multi-keyframe image-to-video guide frames: 1-64 image URLs pinned at the positions given by keyframe_indexes. Mutually exclusive with image_url, end_image_url, and loop; unlocks 10s and HDR. Provide keyframes and keyframe_indexes together (same length).
`exr_export`	boolean	Optional	Also export an EXR file alongside the MP4. Requires hdr=true and HDR access. · Default: false
`resolution`	string	Optional	Resolution of the generated video. Higher resolutions cost more. · Options: 540p, 720p, 1080p · Default: "540p" 540p720p1080p
`aspect_ratio`	string	Optional	The aspect ratio of the generated image. · Options: 21:9, 16:9, 3:2, 4:3, 5:4, 1:1, 4:5, 3:4, 2:3, 9:16 21:916:93:24:35:41:14:53:42:39:16
`keyframe_indexes`	integer[]	Optional	Output-frame positions (duration x 24fps: 5s -> 0-120, 10s -> 0-240) where each keyframes[i] is anchored. Non-negative, unique, and the same length as keyframes.

Output Schema

Field	Type	Description
`id`	string	Unique identifier for the generation task
`status`	string	Task status: pending, running, completed, failed, timeout
`model`	string	Model used for the generation
`outputs`	array	Array of output items
`outputs[].url`	string	URL of the generated artifact
`outputs[].content_type`	string	MIME type (e.g. image/png, video/mp4)
`error`	object \| null	Error details if failed, null on success
`error.type`	string	Machine-readable error type code
`error.message`	string	Human-readable error description

Async Workflow

This model uses asynchronous execution. Submit a request and poll for the result.

Submit — POST to /v1/run, receive an id
Poll — GET /v1/run/{id} until status is completed, failed, or timeout
Retrieve — Read outputs from the completed response
