Kling 4.0 to add 4K HDR, 30-second video, and 15-reference control

Kling AI says Kling 4.0 will add stereo audio, more accurate lip sync, output up to 4K, and 10-bit HDR. Omni Reference can use up to 15 multimodal references, with enhanced video editing.

The model also supports native 30-second generation and multi-keyframe control for up to 10 keyframes, plus video extension and multiple languages, accents, and dialects. Kling 4.0 is scheduled for this October, while Kling 4.0 Flash is already available to Ultra Yearly subscribers.
