Input

Field	Kind	Default	Description
`image`	JSON	—	Optional input image for image-to-video generation. If provided, generates video with this image as the first frame. Also accepts `input_reference` for compatibility (same semantics — first frame).
`prompt`	text	—	Prompt for video generation. Required for text-to-video (T2V) and reference-to-video (R2V). Optional for image-to-video (I2V) — when omitted, the model generates a video from the image alone.
`duration`	number (whole) 1 to 15	8	Video duration in seconds. Range: [1, 15]. Default: 8. Also accepts `seconds` for OpenAI API compatibility. Accepts both number (8) and string ("8") values.
`keyframes`	JSON	—	Optional mid-video keyframe anchors, strictly between the endpoint pins (`image` as the first frame, `last_frame` as the last). Each entry pins an image to appear literally at its timestamp. Only supported by select video models; at most 4 entries.
`resolution`	one of 480p, 720p, 1080p	—	Resolution of the generated video.
`aspect_ratio`	one of 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, 2:3, 21:9, 5:2	—	Aspect ratio of the generated video. Ignored for image-to-video (first-frame `image` input): the aspect ratio is always derived from the input image.
`reference_audios`	JSON	—	Optional reference audio clips (voice identity) for reference-to-video generation. Each entry supplies a clip via `url` or selects a voice via `voice_id`; caller-supplied clips must be at most 15 seconds long. Only supported by select video models; at most 3 entries. May be provided without `reference_images` (audio-only reference-to-video) — at least one reference of either kind selects the reference-to-video mode.
`reference_images`	JSON	—	Optional reference images for reference-to-video (R2V) generation. When provided generates video using these images as style/content references.
