  "input": {
    "first_frame": "https://example.com/product-shot.jpg",

}'

Parameters

Parameter	Type	Required	Default	Description
`prompt`	string	No	-	Text prompt for video generation
`first_frame`	string	No	-	First frame image to animate into video (jpg/png/bmp/webp, ≤20MB)
`last_frame`	string	No	-	Last frame image for first-and-last-frame video generation (jpg/png/bmp/webp, ≤20MB). Requires first_frame.
`first_clip`	string	No	-	Video clip to continue from (mp4/mov, 2-10s, ≤100MB). Cannot be combined with first_frame.
`audio`	string	No	-	Audio file (wav/mp3, 3-30s, ≤15MB) for voice/music synchronization. If not provided, the model auto-generates matching audio.
`negative_prompt`	string	No	-	Negative prompt — describes content that should not appear in the video
`resolution`	string	No	1080p	Output video resolution 720p1080p
`duration`	integer	No	5	Duration of the generated video in seconds
`enable_prompt_expansion`	boolean	No	true	Automatically expand and optimize the prompt for better results. Improves quality for short prompts but increases latency.
`seed`	integer	No	-	Random seed for reproducible generation. Range: 0-2147483647

How to Provide File Input

There are 3 ways to provide files for the first_framelast_framefirst_clipaudio parameters:
