What is Kling 4?
Kling 4 is an online AI video generator that turns text prompts, images, and reference clips into cinematic videos. It focuses on clean motion, consistent faces, and useful control for creators making ads, storyboards, product videos, and social clips. The site lets you choose text-to-video or image-to-video, set the length, aspect ratio, resolution, and audio, then generate and download an MP4. It also supports native stereo audio, lip sync, multi-keyframe storytelling, and reference inputs to keep shots on track. The homepage says the current engine is available now, while Kling 4.0 itself is announced and coming at launch through the API.
