What Is Kling 4.0?

A multimodal video model that combines reference guidance, synchronized sound and editing.

Kling 4.0 is a video model developed by Kuaishou and released by Kling AI on October 15, 2026. It brings video generation and editing into one model, with longer scenes, richer reference inputs and control over important moments in a story.

Images can guide a character, object, composition or style. Video references can guide movement and camera work, while reusable elements and voice profiles help define recurring subjects.

Start with the material that best describes your idea:

  • Text to video: Describe the scene, action, camera movement and sound in a written prompt.
  • Image to video: Animate a starting image, with an optional ending image to guide the final frame.
  • Keyframe to video: Provide up to 10 images to define the important visual moments in a sequence.
  • Reference to video: Combine images, videos, voice profiles and elements, with up to 15 reference assets in total.
  • Video editing: Use instructions and references to change selected parts of an existing clip.

The specifications below describe the official Kling 4.0 model. Available controls and output options depend on the creation interface.

Key Features of Kling 4.0

Control story length, references, timing, sound, movement and edits within one video model.

More room for a complete scene

Generate 3–30 seconds in one pass, giving an action, conversation or short story time to unfold. Use a continuous take or describe a sequence of shots.

Combine visual and voice references

Guide appearance, composition, motion and vocal identity with up to 15 mixed assets. Separate limits apply to images, videos, elements and voice profiles.

Plan up to 10 key moments

Use keyframe images to guide character states, scene changes and reveals. A first and last frame can also define the beginning and ending of an image-to-video clip.

Create picture and stereo sound together

Generate dialogue, singing, ambience and sound effects with two-channel stereo audio. Lip synchronization helps match the voice to the character's performance.

Transfer motion and camera direction

Use reference footage to guide action, pacing and camera movement while changing the subject or setting. Prompts can also describe tracking shots, pans and orbits.

Edit specific parts of a video

Replace a character or background, remove an unwanted element, or change a visual style. Describe both the intended change and the scene details you want to preserve.

Who Can Create with Kling 4.0?

Bring personal stories, animation, visual communication and video revisions into motion.

Storytellers and video creators

Develop short narratives with planned story beats, consistent characters and dialogue. Use a longer take when the scene needs time to build.

Animators and illustrators

Turn character sheets, drawings and storyboards into moving scenes. Guide the visual style with references, from clay animation to illustrated fantasy.

Designers and communicators

Animate posters, demonstrate an idea or create a product sequence from visual references. Combine motion and sound to make the message easier to follow.

Video editors

Revise existing footage with targeted instructions, such as removing a passer-by or replacing a setting. Keep the unchanged parts of the shot clearly specified.

How to Create with Kling 4.0

Build a clear brief, direct the sequence and review the result.

1

Choose your starting material

Start with text, a first-frame image, a keyframe sequence or reference assets. For an edit, prepare the source video and describe what should change.

2

Describe the action and sound

Explain the scene, timing, camera movement and audio. Give each reference a clear role, such as preserving a character's appearance or following a camera move.

3

Generate and review the clip

Check motion, character consistency, dialogue and any visible text. Refine the instructions or make a targeted edit before choosing the final version.

Kling 4.0 vs Kling 3.0

Official model-level comparison. The Kling 3.0 series includes Omni workflows; these are not the settings of a single generator.

Kling 4.0 Advantages: More room for extended scenes, additional reference assets, multiple keyframes and stereo sound.

Kling 3.0 Series Advantages: A focused fit for shorter scenes that need text or image guidance, start/end frames and native audio.

Choose Kling 4.0 when a story needs longer timing, richer references or finer visual control. Kling 3.0 suits projects whose scene and reference requirements fit within its shorter generation range.

Kling 4.0 Advantages: Dedicated control over up to 10 keyframes, reusable character and object elements, and explicitly documented stereo sound suit scenes with planned visual moments and recurring subjects.

Seedance 2.5 Advantages: A larger mixed-reference capacity, audio-only reference generation, timestamp-based editing and multi-round extension suit projects built from many assets or revised over longer sequences.

Choose Kling 4.0 for explicit keyframe planning, reusable elements and stereo output. Choose Seedance 2.5 when reference capacity, timed audio/video edits or extension matter most. Not listed means the cited documentation does not establish an equivalent feature; it does not prove the feature is unsupported. These specifications do not establish a winner in visual quality, speed or cost.

FAQs

Kling 4.0 FAQs

Answers about inputs, timing, audio, editing and how to guide your results.

1

What is Kling 4.0?

Kling 4.0 is Kuaishou's multimodal video model, released by Kling AI on October 15, 2026. It generates videos with audio from text and visual references, and also supports editing existing clips.

2

How long can a Kling 4.0 video be?

Native generation runs from 3 to 30 seconds, in 1-second increments. A 30-second generation can be a continuous take or a sequence with several story beats.

3

Can Kling 4.0 generate sound and dialogue?

Yes. It generates two-channel stereo audio, including dialogue, singing, ambience and sound effects. Describe the sound you want alongside the visual action, and review lip synchronization in the result.

4

How many references can I combine?

Omni Reference accepts up to 15 assets in total, with separate limits of 10 images, 5 videos, 7 elements and 3 voice profiles. These are individual ceilings, not quantities you can all add together. Reference videos, editing videos and video elements also share a maximum of 5 clips and 30 seconds combined.

5

How are keyframes different from references?

Keyframes define visual moments that the sequence should pass through, with up to 10 images. References describe things such as a character's appearance, scene layout, style or camera movement without necessarily fixing a particular frame.

6

Can I edit an existing video with Kling 4.0?

Yes. Instructions can guide changes to characters, backgrounds, movement, camera direction or style, and can remove selected elements. Identify one primary video and state which parts of the scene should stay the same.

7

What resolutions and aspect ratios does Kling 4.0 support?

Official model documentation lists 720p, 1080p and 4K, with 21:9, 16:9, 1:1 and 9:16 output shapes. Omni Reference also has Auto aspect ratio. The options exposed by a particular creation interface may be narrower.

8

How should I write a Kling 4.0 prompt?

Describe the subject, setting, action, camera and sound. When using references, assign each one a role: for example, use @Image1 for appearance and @Video1 for camera movement. For edits, explain the change and the details to preserve.

9

How does pricing work on Picir AI?

Picir AI offers plans with included credits. Review the plan terms and the generation cost displayed for your selected settings before submitting a task.
