durationinteger
The duration of the video in seconds.

Default: 5

resolutionstring (enum)
The resolution of the generated video. 480P and 768P are native generation modes; 2K and 4K upscale a 768P base result.

Default: 2K

One of: 480P, 768P, 2K, 4K

seedinteger
Random seed. A random seed is selected when omitted.
sync_modeboolean
Return the generated video as base64 instead of a CDN URL.

Default: false

prompt_expansion_modestring
How much effort to spend rewriting the prompt before generation. 'disabled' skips prompt expansion. 'fast' returns in about a second. 'balanced' picks per request. 'quality' spends up to ~30s on a richer prompt.

Default: balanced

aspect_ratiostring (enum)
The aspect ratio of the generated video.

Default: adaptive

One of: adaptive, 21:9, 16:9, 4:3, 1:1, 3:4, 9:16

reference_image_urlsarray of image URLs
URLs of subject/style reference images, referenced in the prompt as Image 1, Image 2, and so on. Reference images, videos, and audio clips must add up to at most 12 files.
target_audio_urlstring (URL)
Optional URL of an audio clip at least 2 seconds long (maximum 15 MB) to pin to the generated soundtrack. Cannot be combined with reference audio. Longer clips are trimmed to the generated video's length, keeping the beginning; shorter clips are padded with silence. The clip is resampled to 32 kHz stereo and replaces the output soundtrack without changing playback speed. Accepts an HTTP(S) URL or a base64 data URI.
