Kling 4.0 AI Video Generator (kling3.io)

Kling 4.0 is an AI video generation tool that helps creators move from a written brief or visual reference to a staged scene, directing movement and refining takes for product campaigns, social clips, and cinematic concepts. It supports text-to-video, image-to-video, and a creative iteration workflow to explore variations of a scene.

Kling 4.0 emphasizes motion and camera direction, allowing prompts to be replaced with example prompts and enabling review of takes before finalizing delivery within a browser-based interface.

The tool provides options to start from a written idea or an image, and to direct the action by describing a main movement and the camera path, with controllable duration and format as part of the credit estimate shown before creation.

Kling 4.0 supports planning and editing through references and keyframes, offering guidance on how to build scenes from prompts and visual anchors while maintaining continuity across revisions.
