  • Supported durations: gen2 extend the video with additional 4s and gen3extend the video with additional 5s
  • Extend withgen3 only compatible with the uuid that used Generate By Text in gen3, and it doesn't works for the uuid that's used Generate By Image or Generate By Image And Description
• text_prompt (required, string): "masterpiece, cinematic, man smoking cigarette looking outside window, moving around"
• seed (optional, int): default to be 0, means random value
• callback_url(optional, string): The callback_url is where a GET request will be sent once the job finishes, whether it’s successful or not. It will include the UUID in this format: ?uuid=
