Vidu 2.0 Start End to Video transforms static images into dynamic videos, incorporating creative storytelling and animations.

This is an asynchronous API; only the task_id will be returned. You should use the task_id to request the [Task Result API](/docs/api-reference/model-apis-task-result) to retrieve the video generation results.
