# Vidu Q1 Text-to-Video

Vidu Q1 Text-to-Video generates smooth and seamless videos using keyframe technology, maintaining a consistent thematic style.

<Tip>
  This is an **async** API that only returns the task\_id of the async task. You should use the task\_id to call the [Get Async Task Result API](/docs/models/reference-get-async-task-result) to retrieve the generated result.
