Input

Field	Kind	Default	Description
`prompt` required	text	—	The text prompt describing the desired video motion. Max 1500 characters.
`image_url` required	URL or file	—	URL of the image to use as the first frame. Must be publicly accessible or base64 data URI. Image dimensions must be between 240 and 7680.
`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.
`resolution`	one of 720p, 1080p	1080p	Video resolution. Valid values: 720p, 1080p

`seed`	number (whole)	—	Random seed for reproducibility. If None, a random seed is chosen.
`generate_audio`	true or false	true	Whether the model generates native audio for the video. Set to false for silent video generation, which is cheaper (half as much as a flash generation with audio)Independent of audio_url, which only provides a track to sync the video against.
