Kling 4.0 delivers more stable, physically convincing action in demanding scenes, from fast-paced fights to sports and large-scale movement. Stronger camera direction supports dynamic tracking, complex camera moves, and more coherent shot composition. With up to 30 seconds of native video generation, create longer takes and connected sequences with greater control over action, pacing, and camera movement.

Kling 4.0's Omni Reference supports up to 15 combined reference assets, including images, videos, and subjects. Combine character, scene, motion, and style references to guide different elements within the same generation. Up to 10 flexible keyframes give you additional control over composition, character actions, and scene progression. Experiment with different reference combinations and key moments without rebuilding your entire creative setup.

Kling 4.0 goes beyond generating new footage. It lets you reference existing videos to explore different characters, products, camera movements, and visual styles while retaining the original shot structure or motion as a guide. It also supports precise video editing, letting you target changes to subjects, backgrounds, actions, and camera angles. Rework existing scenes, try alternate versions, and develop new footage without starting from scratch.







I’ve been using Kling AI since its initial release, and it’s remained one of the leading AI media generators ever since. With Kling AI, I’ve created hundreds of videos, collectively amassing millions of views.

Kling AI has made it easy for us to generate world class visuals for Fortune 500 companies, TV shows and music for big artists. We love the easy of use of the platform and the quality of the generations. My first time using Kling AI, I got 22 million views on just one video. It's that good.

I use Kling AI daily to push the limits of AI filmmaking. It allows me to create highly cinematic content, blending AI and VFX to develop innovative projects. It has significantly impacted my creative process, enabling me to achieve complex animations that would otherwise require high production budgets.
