Defaults to Gemini Omni Flash Edit ("gemini-omni-flash-edit"). image_urls (list[str], optional): Reference images, for models that accept them alongside a source video. duration (str, optional), aspect_ratio (str, optional), resolution (str, optional): forwarded to the model when supported. keep_audio (bool, optional): retain source audio when supported.

Creates a new video record (status="generating") with the same ownership scope as the source video and runs generation in the background.
