Vidu Q3 Turbo start-end-to-video generates high-quality videos from first and last frame images with text-guided motion interpolation, supporting up to 1080p resolution.
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.
