Kling 4.0 Previews 30-Second AI Video

Kling’s meaningful leap is controllability, not just prettier frames: longer native scenes, reference-heavy direction, and synchronized sound push AI video toward production workflows.

• –Native 30-second generation reduces the need to stitch together short clips.
• –Up to 10 keyframes and 15 multimodal references give creators tighter control over continuity, characters, props, and camera direction.
• –4K HDR, stereo audio, and improved lip sync target more professional finishing workflows.
• –Kling 4.0 Flash is currently limited to Ultra Yearly subscribers, with the broader release expected in October.
• –The demos are promising, but production reliability, pricing, API access, and benchmark results remain unproven.
