Kling 4.0 is a Kling AI video generator you can open at the official Kling site. The tool is available on the site now. It is built for people who want a finished clip from one generation pass instead of stitching many short takes together.

With Kling 4.0 you can create videos up to 30 seconds long in a single pass. Output is available at 4K and at 1080p, so you can choose a high resolution master or a lighter 1080p file for faster sharing. The generator also adds stereo audio, which means the soundtrack is delivered in two channels rather than a flat mono mix.

Lip sync is precise. When a character speaks, the mouth movement is meant to follow the audio closely, which matters for dialogue scenes, product explainers, and talking-head clips. You can attach up to 15 reference assets. Those references help the generator keep a person, product, or style consistent across the shot.

The public name of the product is Kling 4.0 – Kling AI Video Generator. Visit the site to try it. The site is the place to start a project, review the current feature set, and create a video. This bookmark is only a pointer to that page.
