Input Schema

12 parameters · 2 required · 10 optional

Parameter	Type	Required	Description
`image`	string	Required	Optional URL of an image to use as the edited video's first frame — e.g. a restyled version of the source's opening frame to steer the look of the edit. Leave unset to let the model derive the first frame from the source video.
`prompt`	string	Required	Text prompt describing how to edit the source video. · 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. · Default: false
`video`	string	Optional	URL of the source video to edit. · Min length: 1
`controls`	string	Optional	Per-signal conditioning controls (pose, depth, normals, trajectory, face) for finer control than edit_strength. Cannot be combined with auto_controls.
`duration`	integer	Optional	Duration of the edited video. · Options: · Default: "5s"
`keyframes`	string[]	Optional	Multi-keyframe edit guide frames: up to 64 image URLs pinned at the source-frame positions given by keyframe_indexes. Mutually exclusive with start_image_url. 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 edited video. Higher resolutions cost more. · Options: 540p, 720p, 1080p · Default: "540p" 540p720p1080p
`auto_controls`	boolean	Optional	Let the model derive the edit conditioning schedule from the source video. Cannot be combined with edit_strength. · Default: false
`edit_strength`	string	Optional	How closely the edit preserves the source video. 'adhere_' stays closest to the source, 'flex_' is balanced, and 'reimagine_*' diverges most. Leave unset to use Luma's default. Cannot be combined with auto_controls. · Options: adhere_1, adhere_2, adhere_3, flex_1, flex_2, flex_3, reimagine_1, reimagine_2, reimagine_3 adhere_1adhere_2adhere_3flex_1flex_2flex_3reimagine_1reimagine_2reimagine_3
`keyframe_indexes`	integer[]	Optional	Source-video frame positions 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
