Input parameters

Name	Type	Required	Description
`prompt`	string	optional	Text prompt. Chinese and English are supported. Up to 20,000 characters; excess characters are truncated automatically. Required for text-to-video; for other modes, it is recommended to provide it together with media. In reference mode, use Image1/Video1/Audio1 to reference the provided materials.
`first_frame_url`	object	optional	URL of the first-frame image. Up to 1 image, used strictly as the first frame of the video. Used for first-frame-to-video or first-and-last-frame-to-video generation. Cannot be provided together with `reference_*_urls`. Formats: JPEG/JPG, PNG (transparency not supported), BMP, WEBP; each side [240, 8000] px; aspect ratio ≤ 8:1; ≤ 20MB.
`last_frame_url`	object	optional	URL of the first-frame image. Up to 1 image, used strictly as the first frame of the video. Used for first-frame-to-video or first-and-last-frame-to-video generation. Cannot be provided together with `reference_*_urls`. Formats: JPEG/JPG, PNG (transparency not supported), BMP, WEBP; each side [240, 8000] px; aspect ratio ≤ 8:1; ≤ 20MB.
`reference_image_urls`	array	optional	Reference images for all-purpose reference mode. Up to 10 images. Correspond to Image1, Image2, and so on in the prompt according to array order. Same specifications as `first_frame_url`. Cannot be provided together with the first-frame or last-frame image.
`reference_video_urls`	array	optional	Reference videos for all-purpose reference mode. Up to 5 videos. Each video must be 1–15s, with a combined duration of ≤ 15s. Correspond to Video1, Video2, and so on according to array order. Formats: mp4, mov; each side [240, 4096] px; aspect ratio ≤ 8:1; each file ≤ 100MB. There is an additional output-side limit: the input video duration plus `duration` cannot exceed 30 seconds.
`reference_audio_urls`	array	optional	Reference audio files for all-purpose reference mode. Up to 5 audio files. Each file must be 1–15s, with a combined duration of ≤ 15s. Correspond to Audio1, Audio2, and so on according to array order. Formats: wav, mp3; ≤ 15MB. Even when used as the only media input, it is still recommended to provide an image or video together with it.
`reference_file_urls`	array	optional	File-to-video generation. Up to 1 file. Cannot be provided together with `reference_link_urls`, or with the first-frame/last-frame image. Formats: docx/doc/xlsx/xls/pptx/ppt/pdf/txt/key/pages/numbers/md; ≤ 100MB; pdf/docx/ppt/key/pages, etc. ≤ 50 pages.
`reference_link_urls`	array	optional	Link-to-video generation. Up to 1 publicly accessible webpage that does not require login. Cannot be provided together with `reference_file_urls`, or with the first-frame/last-frame image.
`resolution`	string	optional	Output resolution level. Default: 1080P. Values: `480P`, `720P`, `1080P` Default: `1080P`
`aspect_ratio`	string	optional	Output aspect ratio. `adaptive` (default) automatically selects the aspect ratio based on the input materials and intent. Values: `adaptive`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` Default: `adaptive`
`duration`	integer	optional	Output video duration in seconds. Default: 5. When there is no video input, the value must be within [2, 30]. When reference videos are provided: input video duration plus output duration ≤ 30. Pass `-1` to use an intelligent duration determined by the model. Default: `5`
`audio`	boolean	optional	Whether the output video includes an audio track. Default: true. Default: `True`
`seed`	integer	optional	Random seed used to reproduce results. If omitted, a random seed is used.
