Input

Field	Kind	Default	Description
`prompt` required	text	—	The text prompt for video generation. Supports Chinese and English, max 1500 characters. For multi-shot videos, use format: 'Overall description. First shot [0-3s] content. Second shot [3-5s] content.'
`audio_url`	URL or file	—	URL of the audio to use as the background music. Must be publicly accessible. Limit handling: If the audio duration exceeds the duration value (5, 10, or 15 seconds), the audio is truncated to the first N seconds, and the rest is discarded. If the audio is shorter than the video, the remaining part of the video will be silent. For example, if the audio is 3 seconds long and the video duration is 5 seconds, the first 3 seconds of the output video will have sound, and the last 2 seconds will be silent. - Format: WAV, MP3. - Duration: 3 to 30 s. - File size: Up to 15 MB.
