# OpenAI Sora 2 Image-to-Video

OpenAI Sora 2 converts a single reference image into a coherent video clip with synchronized audio. Based on Sora 2's core advancements, the image-to-video workflow preserves identity, lighting, and composition while synthesizing believable motion and camera dynamics.

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