What is Kling 4.0 – Kling AI Video Generator?
Kling 4.0 is a Kling AI video generator aimed at finished clips rather than rough tests. It renders native 4K output up to 30 seconds long. A 10-keyframe timeline sets the beats of a scene, and up to 15 multimodal references (images, clips or style cues) keep a character or product consistent across shots. Audio is generated in the same render. Use cases include product demos, short ads and social cuts. Freemium, on the web at kling4.tv.
