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.
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 to retrieve the video generation result.
