Can I use Ingredients with just one image?
Yes, you can input 1–3 images, and one image also meets the requirements. However, creation here still follows the reference fusion approach and is not equivalent to a fixed first frame. It is recommended to specify in the prompt the main content you want to preserve, as well as the desired action or scene changes.
How do I submit a multi-image fusion task?
Send a POST request to /veo/videos, set model to veo31-fast-ingredients, use the ingredients2video operation, provide image links through image_urls, and use prompt to describe the fusion relationship and camera intent. Images must be provided.
What is the main difference between it and veo31-fast?
Ingredients requires images and focuses on fusing reference content; veo31-fast supports text-only generation, as well as a single-image first frame and two-image first and last frames. Choose the former when you want to combine assets, and the latter when you want to start from a specified image or connect specified first and last images.
Can I generate 1080p or vertical video assets?
You can select 1080p and choose 9:16 vertical or 16:9 horizontal through aspect_ratio. When output settings are not specified, 720p is used by default. When planning vertical video assets, it is recommended to also specify the subject position and composition in the prompt, to avoid changing only the aspect ratio without adjusting the camera design.
How do I get the video after asynchronous submission?
After setting async=true, first obtain the task_id, then retrieve the status and result through task queries; you can also use callback_url to receive completion notifications. After completion, read video_url from data to get the video, and save the video ID to facilitate linking generation records and subsequent processing.
