PixVerse V6 Video Extension analyzes the ending segment of an existing video and generates new frames forward, continuing and enhancing the video content while maintaining natural motion and dynamic scene effects.
This is an asynchronous API and only returns the asynchronous task’s task_id. You should use this task_id to request the Get Task Result API to retrieve the generation result.
