Introducing the model

What Is Kling 4.0?

Kling 4.0 is a new generation of Kling's AI video model built for longer video generation, stronger creative control, and richer audio-visual output.

The model supports text-to-video and image-to-video workflows, along with first and last frames, multi-keyframes, and Omni Reference. It can generate videos from 3 to 30 seconds and use images, videos, subjects, and voice references to guide a scene.

Kling 4.0 is designed for creators, marketing teams, e-commerce brands, and production workflows that need more control over characters, camera movement, dialogue, and visual consistency.

What's new

What's New in Kling 4.0?

More control does not just mean adding a longer prompt. Kling 4.0 gives you more ways to define how a scene should look, move, sound, and develop over time.

Up to 30 Seconds of Native Video

Create videos from 3 to 30 seconds in one generation. The longer duration gives actions, dialogue, camera movement, and story beats more room to develop within the same clip.

Up to 10 Keyframe Images

Use as many as 10 keyframe images to define important visual moments. Set character states, scene changes, compositions, and story beats instead of relying only on a text prompt.

Up to 15 Multimodal References

Combine up to 15 reference items across images, videos, subjects, and voice references, including up to 10 images, 5 videos totaling 30 seconds, and 7 subject elements within documented limits.

More Precise Motion and Camera Control

Guide high-speed movement, continuous actions, tracking shots, orbit shots, and other complex camera motion. Video references can define actions, timing, movement, and pacing.

Stereo Audio and Improved Lip Sync

Two-channel stereo audio and improved synchronization between voices, dialogue, and on-screen performances support dialogue, narrative, and social content.

Professional-Grade 4K & 1080p Output

Create high-quality video with output specifications up to 4K and 1080p, enhanced by 10-bit HDR for richer color, smoother gradients, and greater detail across highlights and shadows.

Video Editing and Extension

Use text, images, subjects, and video inputs to guide edits to existing footage. Video extension availability may depend on rollout and platform integration.

Real outputs, not marketing claims

Kling 4.0 may be more useful when a project needs longer sequences, more reference inputs, or finer control over important story moments.

Kling 3.0 can still make sense when your current workflow already meets the required duration and control level.

Three-step workflow

How to Use Kling 4.0

01

Describe the video you want

Start with the subject, action, environment, camera direction, and important visual details. For dialogue scenes, include who is speaking and how the performance should feel.

02

Add references or keyframes

Upload image or video references when text alone is not precise enough. Use keyframes for important visual moments and Omni Reference for consistent characters, products, actions, or camera behavior.

03

Choose your settings and generate

Select the available duration, aspect ratio, and output options. Review identity, motion, text, audio, and continuity, then adjust the prompt or references where needed.

Use cases

Prompting

Kling 4.0 Prompt Guide

A strong Kling 4.0 prompt should describe what happens, when it happens, how the camera moves, and what must stay consistent.

30-Second Narrative Prompt

A woman enters a quiet late-night diner during heavy rain. Begin with a wide exterior shot through the wet window. Follow her as she walks toward the counter. At the midpoint, move into a close-up as she notices an old photograph beside the register. End with a slow pullback as the lights outside flicker.

Use this format when a clip needs clear progression rather than a single continuous action.

Multi-Keyframe Prompt

Keep the same character and clothing across all keyframes. Move naturally from the opening street scene to the interior café, then to the final close-up. Preserve facial identity, lighting direction, and the red coat throughout the sequence.

Use keyframes to establish the important visual checkpoints. Use the prompt to describe how the model should move between them.

Camera Motion Prompt

Follow the cyclist from a low rear tracking angle, accelerate beside the subject, then move into a smooth orbit as the cyclist stops at the overlook. Keep the horizon stable and preserve realistic motion blur.

Be specific about camera direction rather than relying only on words such as “cinematic.”

Dialogue Prompt

Two friends speak quietly across a small kitchen table. The woman on the left delivers the first sentence in American English. The man pauses before answering. Keep the delivery natural, with subtle facial expressions and restrained hand movement.

For dialogue, identify the speaker and performance instead of placing all spoken content into one undifferentiated paragraph.

Multi-Reference Product Prompt

Use the product reference for exact shape and overall color direction. Use the motion reference for the camera move. Keep the product centered during the orbit and place it in the environment shown by the location reference.

Tell the model what each reference is supposed to control.

Quality control

What to Check Before Using a Result

AI video output should be reviewed before publishing or delivering it to a client.

Character Identity

Check faces, clothing, body proportions, and important identity details across longer scenes and transitions.

Hands and Small Objects

Inspect fingers, accessories, tools, packaging, and other small elements that may be important to the shot.

Text and Logos

Review spelling, typography, labels, product marks, and logo details closely. Do not assume generated text is production-ready without checking it.

Lip Sync and Audio

Listen to dialogue while watching mouth movement and speaker changes. Check pronunciation, timing, stereo balance, and whether the intended person is speaking.

Long-Scene Continuity

For longer videos, review character position, lighting, props, environments, and camera direction from beginning to end.

Reference Conflicts

Too many references can communicate conflicting instructions. If the result drifts, simplify the reference set and make the purpose of each input clearer.
