# VIDU Q2 Pro Multi-frame to Video

Generate coherent videos from multiple keyframe images. Supports 540p, 720p, and 1080p resolutions.

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