The PixVerse C1 first-and-last-frame-to-video model generates smooth video transition effects based on a starting frame and an ending frame. It supports multiple resolution and duration configurations, with optional synchronized audio generation.
This is an asynchronous API and only returns the asynchronous task_id. You should use this task_id to request the Get Task Result API to retrieve the generated result.
