Vidu 2.0 Reference to Videos generates videos using a reference image and text description. It supports various subjects, such as characters and objects. By uploading multiple perspectives of a subject, you can create videos that maintain visual consistency.
This is an asynchronous API; only the task_id will be returned. You should use the task_id to request the Task Result API to retrieve the video generation results.
