How to use Kling 3 4K

Getting started

Use a compact visual brief for a new scene, keeping the action readable. Select image-to-video when a specific opening image matters.

Review your result

Inspect fine moving detail at full size, particularly faces and hard edges. Review generated speech and the closing frame.

Inputs and settings

Write prompt, then select duration of 3–15 seconds and aspect_ratio. Choose generate_audio; cfg_scale within 0–1 adjusts prompt adherence.

Use negative_prompt for unwanted details. Image-to-video requires start_image_url and optionally accepts end_image_url; choose compatible frames before describing their transition.
