# Vidu Q3 Turbo Text-to-Video

Vidu Q3 Turbo Text-to-Video can generate high-quality videos with synchronized audio based on text descriptions, supporting up to 1080p resolution and durations from 1 to 16 seconds.

<Tip>
  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](/en/docs/models/reference-get-async-task-result) to retrieve the generated result.
