# VIDU Q2 Pro Fast Image-to-Video

Generate a new video based on reference images (fast mode). Supports both 720p and 1080p resolutions. Fast mode can significantly reduce generation time and is suitable for scenarios with high speed requirements.

<Tip>
  This is an **asynchronous** API and will only return the asynchronous task's task\_id. You should use this task\_id to request the [Get Task Result API](/en/docs/models/reference-get-async-task-result) to retrieve the generated result.
