Submit the request with `VIDGO_API_KEY`. A `task_id` is returned immediately. Keep it until the task reaches `finished` or `failed`. 2. Use [Query Task Status](/api-manual/task-management/status) to retrieve the result. If you provide a `callback_url`, Vidgo sends the result to your [webhook](/api-manual/task-management/webhooks) when the task finishes or fails. # Wan 2.6 Reference to Video Use reference videos to guide new scenes with Wan 2.6, with support for multiple shots and video output up to 1080p. ## Available Models * **alibaba/wan-2.6/reference-to-video** - Generate video guided by reference material and a prompt. ## Duration Options * **5, 10 seconds** - Set `duration` as an integer.
