# Veo3 비디오 생성

> Generate high-quality videos using Google Veo3 model, supports async task management

* Asynchronous processing mode, returns task ID for subsequent queries
* Supports multiple generation modes including text-to-video and image-to-video
* Generated video links are valid for 24 hours, please save them promptly

<Warning>
  **Important Change**: For better performance and cost control, we no longer support passing base64 image data directly in `image_urls`. Please use the [Upload 이미지 API](../../uploads/images) first to upload images and get URLs, then call this endpoint.
</Warning>
