Input

Field	Kind	Default	Description
`prompt` required	text	—	Text prompt for video generation
`duration`	number (whole) 5 to 15	5	The duration of the video in seconds.
`resolution`	one of 480P, 768P, 2K, 4K	2K	The resolution of the generated video. 480P and 768P are native generation modes; 2K and 4K upscale a 768P base result.
`seed`	number (whole)	—	Random seed. A random seed is selected when omitted.
`prompt_expansion_mode`	text	balanced	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.
`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.
