Input Parameters

Name	Type	Description	Default	Constraints
`image`*	string(uri)	Input image for video generation	`—`	—
`prompt`*	string	Text prompt for video generation	`—`	—
`audio`	string(uri)	Audio file (wav/mp3, 3-30s, ≤15MB) for voice/music synchronization	`—`	—
`audio_enabled`	boolean	Whether to generate video with audio. When enabled, the model will auto-generate audio or use provided audio file. Disable for silent video output.	`true`	—
`duration`	integer	Duration of the generated video in seconds	`5`	51015
`enable_prompt_expansion`	boolean	If set to true, the prompt optimizer will be enabled	`true`	—
`multi_shots`	boolean	Enable intelligent multi-shot segmentation (only active when enable_prompt_expansion is enabled). True enables multi-shot segmentation, false generates single-shot content.	`false`	—
`negative_prompt`	string	Negative prompt to avoid certain elements	`""`	—
`resolution`	string	Video resolution	`"720p"`	720p1080p
`seed`	integer	Random seed for reproducible generation	`—`	—
