One of the following:
"3:1"
"2:1"
"21:9"
"16:9"
"4:3"
"3:2"
"1:1"
"3:4"

image_ref: Optional[Iterable[ImageRefParam]]

Reference images for style/content guidance. Up to 9 for type 'image', up to 8 for type 'image_edit'.

data: Optional[str]

Base64-encoded image or video data

generation_id: Optional[str]

UUID of a prior generation owned by the same caller. Used on source for image_edit, video_edit, and video_reframe chaining and on video.start_frame / video.end_frame for video extension.

formatuuid
media_type: Optional[str]

MIME type (for example, image/jpeg or video/mp4). Required with data. Required with source.url on video_edit/video_reframe so the route can dispatch video ingest before fetching bytes; optional for image URLs.

url: Optional[str]

Publicly accessible image URL, or a video URL when used as source for video_edit/video_reframe with media_type=video/*.

model: Optional[Model]

Model identifier. uni-1 is the default image tier; uni-1-max produces higher-quality output than uni-1 at a higher per-image price. ray-3.2 is the public video model for text-to-video, image-to-video, and video-to-video editing.

One of the following:
"uni-1"
"uni-1-max"
"ray-3.2"
output_format: Optional[Literal["png", "jpeg"]]

Output image format

One of the following:
"png"
"jpeg"
source: Optional[ImageRefParam]

Media reference for guided generation. Provide exactly one of url, inline base64 data, or generation_id. URL/data references accept image media at image positions; video_edit and video_reframe sources also accept source.url or source.data when source.media_type is a video/* MIME. generation_id chains image_edit off a prior image output, video_edit/video_reframe off a prior video output, and video.start_frame/end_frame for extension.

data: Optional[str]

Base64-encoded image or video data

generation_id: Optional[str]

UUID of a prior generation owned by the same caller. Used on source for image_edit, video_edit, and video_reframe chaining and on video.start_frame / video.end_frame for video extension.

formatuuid
media_type: Optional[str]

MIME type (for example, image/jpeg or video/mp4). Required with data. Required with source.url on video_edit/video_reframe so the route can dispatch video ingest before fetching bytes; optional for image URLs.

url: Optional[str]

Publicly accessible image URL, or a video URL when used as source for video_edit/video_reframe with media_type=video/*.

style: Optional[Literal["auto", "manga"]]

Style preset (auto, manga)

One of the following:

One of the following:
"image"
"image_edit"
"video"
"video_edit"
"video_reframe"
user_id: Optional[str]

Your end-user's stable opaque identifier (no PII). Forwarded to upstream model providers as their per-user tagging field so trust & safety violations can be attributed to a specific end-user rather than the whole API account. Also used for per-end-user usage breakdowns in /v1/usage. Strongly recommended for partner integrations.

maxLength256
video: Optional[VideoOptionsParam]

Ray 3.2 video request options. Common output settings live at the top level for type=video, type=video_edit, and type=video_reframe; video-to-video conditioning lives under edit.

pose: Optional[PoseControl]

Pose / skeleton conditioning control

enabled: Optional[bool]

Enable or disable pose conditioning. Omit to use the model default.

strength: Optional[PoseControlStrength]

Pose-conditioning strength

One of the following:
"precise"
"coarse"
trajectory: Optional[TrajectoryControl]

Motion-trajectory conditioning control

enabled: Optional[bool]

Enable or disable trajectory conditioning. Omit to use the model default.

sparsity: Optional[float]

Point-trajectory sparsity from 0 to 1. Higher values use fewer motion anchors.

formatfloat
minimum0
maximum1
keyframe_indexes: Optional[List[int]]

Parallel list of non-negative, unique frame positions in the source video's frame grid where each keyframes[i] is anchored. Must match keyframes in length.

keyframes: Optional[List[ImageRef]]

Multi-anchor guide-frame images at arbitrary source-frame positions (parallel with keyframe_indexes). Up to 64 anchors. Mutually exclusive with video.start_frame (the single-anchor case). Each entry takes the same ImageRef shape as source / image_ref[].

data: Optional[str]

Base64-encoded image or video data

generation_id: Optional[str]

UUID of a prior generation owned by the same caller. Used on source for image_edit, video_edit, and video_reframe chaining and on video.start_frame / video.end_frame for video extension.

formatuuid
media_type: Optional[str]

MIME type (for example, image/jpeg or video/mp4). Required with data. Required with source.url on video_edit/video_reframe so the route can dispatch video ingest before fetching bytes; optional for image URLs.

url: Optional[str]

Publicly accessible image URL, or a video URL when used as source for video_edit/video_reframe with media_type=video/*.

strength: Optional[VideoEditStrength]

How much a video edit preserves or reimagines the source

One of the following:

end_frame: Optional[ImageRef]

Media reference for guided generation. Provide exactly one of url, inline base64 data, or generation_id. URL/data references accept image media at image positions; video_edit and video_reframe sources also accept source.url or source.data when source.media_type is a video/* MIME. generation_id chains image_edit off a prior image output, video_edit/video_reframe off a prior video output, and video.start_frame/end_frame for extension.

data: Optional[str]

Base64-encoded image or video data

generation_id: Optional[str]

UUID of a prior generation owned by the same caller. Used on source for image_edit, video_edit, and video_reframe chaining and on video.start_frame / video.end_frame for video extension.

formatuuid
media_type: Optional[str]

MIME type (for example, image/jpeg or video/mp4). Required with data. Required with source.url on video_edit/video_reframe so the route can dispatch video ingest before fetching bytes; optional for image URLs.

keyframe_indexes: Optional[List[int]]

Parallel list of non-negative, unique output-frame positions where each keyframes[i] is anchored, in the duration x 24fps grid (5s -> 0..120, 10s -> 0..240). Must match keyframes in length.

keyframes: Optional[List[ImageRef]]

Image-to-video guide frames (type=video only), each pinned to an output-frame position via the parallel keyframe_indexes. 1-64 anchors: a single anchor is a valid start-pinned i2v (an alternate to start_frame), and any count up to 64 places guide frames at arbitrary positions. Unlike start_frame/end_frame (the legacy 2-frame surface), this supports arbitrary positions, 10s durations, and HDR. Mutually exclusive with start_frame / end_frame / loop. Only supported on model ray-3.2. For video-to-video keyframes use video.edit.keyframes on type=video_edit instead.

data: Optional[str]

Base64-encoded image or video data

generation_id: Optional[str]

One of the following:
"360p"
"540p"
"720p"
"1080p"
source_position: Optional[SourcePosition]
