Input

Field	Kind	Default	Description
`prompt` required	text	—	Text prompt for video generation
`duration`	number 0.92 to 15	5	Video length in seconds. The output can run up to about 0.7 s longer than requested. Use at least 2 s with target_audio_url.
`resolution`	one of 480P, 768P, 1080P	768P	The native generation resolution, or 1080P latent refinement from a native 768P source.
`seed`	number (whole)	—	Random seed. A random seed is selected when omitted.
`prompt_expansion_mode` required	text	balanced	How much effort to spend rewriting the prompt before generation. 'disabled' skips prompt expansion. 'balanced' returns in about a second. 'quality' spends up to ~30s on a richer prompt.
`target_audio_url`	URL or file	—	Optional URL of an audio clip at least 2 seconds long (maximum 15 MB) to pin to the generated soundtrack. Longer clips are trimmed to the generated video's length, keeping the beginning. The original audio replaces the output soundtrack, padded with silence if shorter than the video, without changing playback speed. Exceptionally high sample rates may be resampled to 96 kHz. Accepts an HTTP(S) URL or a base64 data URI.
`aspect_ratio`	one of 21:9, 16:9, 4:3, 1:1, 3:4, 9:16	16:9	The aspect ratio of the generated video.
