Description
Kling 4.0 is a generative AI video model that combines video generation, multimodal references, audio, storytelling controls, and video editing within a unified creative system. The model supports text-to-video and image-to-video generation along with first and last frames, Omni Reference, and multi-keyframe workflows. Creators can generate videos between 3 and 30 seconds long and define as many as 10 keyframes to control character states, scene changes, and important narrative moments. Output options include 720p, 1080p, and 4K resolutions as well as aspect ratios ranging from 21:9 ultrawide to vertical 9:16. Its Omni Reference system can incorporate up to 15 reference assets using combinations of images, videos, voice references, and defined subjects. Image references can guide characters, layouts, styles, graphics, composition, and story beats, while video references can provide direction for performances, actions, camera movements, and pacing. Kling 4.0 also improves dynamic motion, camera direction, stereo audio, lip synchronization, multilingual speech, and text generation for more complete audiovisual productions. Editing tools enable targeted changes to expressions, body movements, camera positions, backgrounds, visual styles, and other elements without requiring the entire scene to be recreated. Kling AI is also introducing Kling 4.0 Flash as a faster option for frequent generation, with support for text-to-video, image-to-video, Omni Reference, 3- to 20-second clips, and 720p output.
