Kling 2.5 Turbo Image-to-Video can generate cinematic videos from a single image and a prompt, with smooth motion and content that closely matches the intended direction. It features a new text-temporal engine, enhanced motion performance, and faster inference speed.
This is an asynchronous API and only returns the asynchronous task’s task_id. You should use this task_id to request the Get Task Result API to retrieve the video generation result.
