Native 30-second storytelling
1

Native 30-second storytelling

Generate up to 30 seconds of video natively in a single creation. The longer timeline gives a scene enough room for an opening, development, action, dialogue, camera movement, and a clear ending without relying on several separately generated clips.

Up to 10 keyframes for precise direction
2

Up to 10 keyframes for precise direction

Guide important moments with multi-keyframe control using up to 10 keyframes. Define how a scene begins, where characters or cameras should move, and how the sequence should end while Kling 4.0 generates the motion between those visual beats.

Up to 15 multimodal references
3

Up to 15 multimodal references

Use Omni Reference to combine up to 15 multimodal references and give the model richer creative context. Reference images, video, subjects, and supported voice information can help preserve characters, products, environments, visual styles, movement, and performance across a scene.

Up to 4K with 10-bit HDR

Up to 4K with 10-bit HDR

Stereo audio and accurate lip sync

Stereo audio and accurate lip sync
