Vidu 2.0 Start and End Frames generates dynamic videos from a starting frame and an ending frame, incorporating creative storytelling and animation effects.
This is an asynchronous API and only returns the async task’s task_id. You should use this task_id to request the Get Task Result API to retrieve the video generation result.
