imageUrl
string必填—

mage resolution: The width and height of the image range from 240 to 8000 pixels. File size: Maximum 10 MB.

audioUrl
string可选—

Audio file URL; the model will use this audio to generate a video. Duration: 3–30 seconds. File size: no more than 15 MB. Oversize handling: If the audio length exceeds the specified duration value (e.g., 5 seconds), the first 5 seconds will be automatically captured and the rest discarded. If the audio is shorter than the video duration, the portion beyond the audio length will be silent in the video. For example: if the audio is 3 seconds long and the video duration is set to 5 seconds, the output video will have sound for the first 3 seconds and be silent for the remaining 2 seconds.
