How to use Kling O3 4K
Getting started
Choose text-to-video, image-to-video, reference-to-video, video editing or video-to-video reference for the source you have.
Review your result
Review character identity, motion, camera movement and the soundtrack throughout the clip. Compare edits with the source.
Inputs and settings
For text or image generation, use prompt or multi_prompt, not both. Choose 3–15 seconds; generate_audio controls generated sound. Image mode requires image_url.
Reference and Edit modes support elements: add a frontal image and 1 or 3 extra views per image element (2 extra views are not accepted), then use @Element1 in the prompt. image_urls are separate references, named @Image1.
Edit requires video_url and prompt. keep_audio controls source sound. A video input permits at most four elements and separate reference images combined; the extra views inside an element stay grouped with it.
