Input Parameters

Name	Type	Description	Default	Constraints
`audio`	string(uri)	Audio file (wav/mp3, 3-30s, ≤15MB) for voice/music synchronization. If not provided, the model auto-generates matching audio.	`—`	—
`duration`	integer	Duration of the generated video in seconds	`5`	min: 2, max: 15
`enable_prompt_expansion`	boolean	Automatically expand and optimize the prompt for better results. Improves quality for short prompts but increases latency.	`true`	—
`first_clip`	string(uri)	Video clip to continue from (mp4/mov, 2-10s, ≤100MB). Cannot be combined with first_frame.	`—`	—
`first_frame`	string(uri)	First frame image to animate into video (jpg/png/bmp/webp, ≤20MB)	`—`	—
`last_frame`	string(uri)	Last frame image for first-and-last-frame video generation (jpg/png/bmp/webp, ≤20MB). Requires first_frame.	`—`	—
`negative_prompt`	string	Negative prompt — describes content that should not appear in the video	`""`	—
`prompt`	string	Text prompt for video generation	`""`	—
`resolution`	string	Output video resolution	`"1080p"`	720p1080p
`seed`	integer	Random seed for reproducible generation. Range: 0-2147483647	`—`	—

audiostring

Audio file (wav/mp3, 3-30s, ≤15MB) for voice/music synchronization. If not provided, the model auto-generates matching audio.

durationinteger
