# PixVerse C1 Image-to-Video

The PixVerse C1 image-to-video model converts static images into cinematic dynamic videos, supporting durations of 1–15 seconds, up to 1080p resolution, and optional native audio generation.

<Tip>
  This is an **asynchronous** API and will only return the task\_id of the asynchronous task. 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.
