What Is Kling 4.0?

Kling 4.0 is Kuaishou’s next-generation AI video model, designed for higher-quality generation, more precise control, and more complex visual storytelling.

The biggest change is not one individual feature. Kling 4.0 represents a shift from generating isolated short clips toward a more complete and controllable video creation workflow.

Compared with Kling 3.0, Kling 4.0 gives creators more ways to control video structure, pacing, references, consistency, and editing.

Longer generation, multi-keyframe control, multimodal references, targeted editing, and native long-form creation make it particularly relevant to projects where continuity and storytelling matter.

That includes:

Short films
AI animation
Music videos
Advertising
Ecommerce content
Brand campaigns
Serialized social content
Multi-scene storytelling

The direction is clear: AI video is moving beyond “write a prompt and get one clip.”

Kling 4.0 is designed to give creators more control over what happens between the first and last frame.

What Has Been Confirmed About Kling 4.0?

Up to 30-Second Standard Generation

Kling 4.0 supports standard video generation from 3 to 30 seconds.

That is a meaningful step up from Kling 3.0’s 3-to-15-second generation range and gives creators more room to build a complete scene before reaching the end of a clip.

Longer single generations can be useful for:

Dialogue scenes
Product demonstrations
Commercials
Story-driven social content
Music video sequences
Educational content
Character interactions

The practical advantage is simple: fewer individual clips need to be generated and stitched together.

That can help reduce sudden changes in characters, backgrounds, visual style, audio, and pacing between separate generations.

Up to 10 Keyframes

Kling 4.0 supports up to 10 keyframe inputs.

Rather than defining only a start frame or end frame, creators can use multiple keyframes to anchor important moments throughout the video.

For example:

2 keyframes can define the beginning and ending
5 can guide major transitions
10 can provide much more detailed control over a full sequence

Keyframes can help guide:

Camera positions
Character actions
Scene transitions
Visual progression
Story pacing
Important story beats

Keyframes themselves are not unique to Kling 4.0, but the combination of multiple keyframes, longer generation, richer references, and targeted editing makes them more useful for complex production.

Up to 15 Multimodal References

Kling 4.0 can work with up to 15 reference assets in a generation.

The current model information includes support for up to:

10 images
5 videos
Audio references
Other visual elements

The combined duration of referenced videos can reach up to 30 seconds.

Different reference types can play different roles.

Images can establish:

Character appearance
Product identity
Environment
Costume
Art direction
Visual style

Videos can guide:

Movement
Camera language
Action
Pacing
Choreography

Audio can help maintain voice characteristics and audiovisual identity.

For character-driven projects, this could make it easier to maintain a recognizable visual identity across multiple scenes.

Native Long-Form Video Up to 120 Seconds

One of the biggest upgrades is Kling 4.0’s native long-form workflow.

According to the current model specifications, Kling 4.0 supports native long-form video generation from 30 to 120 seconds.

The important part here is not only the duration.

Kling 4.0 is designed to continue the narrative within the same underlying generation architecture instead of relying only on a series of independently generated clips.

The model also supports:

Forward video extension
Backward video extension
Video insertion
Local regeneration of specific sections

That opens up more practical workflows for:

AI short films
Animation
Branded storytelling
Music videos
Narrative social content
Longer product stories

For creators working on larger multi-scene projects, Loova’s Agentic Canvas provides a workspace for planning scenes, organizing assets, generating content, and refining a project in one place.

Output Options Up to 4K

Kling 4.0 supports:

720p
1080p
4K

The current model specifications also show 10-bit HDR support at 1080p and 4K.

Higher resolution and wider dynamic range can provide more flexibility for:

Film production
Commercial video
Large displays
Cropping
Reframing
Post-production
Brand campaigns

Actual output options may depend on the generation mode and platform implementation.

Kling 4.0 vs Kling 3.0: What Actually Changed?

Kling 3.0 already pushed the Kling series toward stronger multi-shot storytelling, native audio, and reference-based consistency.

Kling 4.0 expands that workflow with longer generation, more reference inputs, multi-keyframe control, more precise editing, and native long-form video creation.

Feature	Kling 3.0	Kling 4.0
Standard Video Length	3–15s	3–30s
Native Long-Form Generation	Not supported	30–120s
Multiple Keyframes	More limited	Up to 10
Multimodal References	Supported	Up to 15
Video Editing	Supported workflows	More precise targeted editing
Resolution	720p, 1080p, 4K	720p, 1080p, 4K
Dynamic Range	8-bit SDR	10-bit HDR at supported resolutions
Audio	Mono	Dual-channel stereo
Main Focus	Cinematic short-form generation	Longer, more controllable video workflows

So What Is the Real Upgrade?

Kling 3.0 improved the quality and structure of cinematic short-form AI video.

Kling 4.0 expands that foundation into a broader production workflow.

The goal is no longer only:

Generate a good-looking clip.

It is increasingly:

Generate, control, extend, edit, and connect a more complete video project.

That shift is more important than any single headline feature.

Kling 4.0 vs Seedance 2.5 vs Seedance 2.0 vs Kling 3.0

Kling 4.0 is entering an increasingly competitive generation of AI video models.

Compared with Seedance 2.0, Seedance 2.5, and Kling 3.0, its differences go beyond video length or resolution. The four models take different approaches to long-form creation, audio, language support, prompt capacity, output quality, and overall production workflow.

Here is a closer look at how they compare based on their current specifications.

Feature	Seedance 2.0	Seedance 2.5	Kling 3.0	Kling 4.0
Standard Video Length	4–15s	4–30s	3–15s	3–30s
Long-Form Video	Not supported	30–180s via Agentic workflow	Not supported	30–120s native generation
Resolution	720p, 1080p, 4K	480p, 720p, 1080p	720p, 1080p, 4K	720p, 1080p, 4K
Dynamic Range / Color Depth	Selected modes support 10-bit	10-bit currently not supported	8-bit SDR	10-bit HDR at 1080p and 4K
Aspect Ratios	21:9, 16:9, 4:3, 1:1, 3:4, 9:16, Auto	21:9, 16:9, 4:3, 1:1, 3:4, 9:16, Auto	16:9, 1:1, 9:16, Auto	16:9, 1:1, 9:16, 21:9, Auto

Prompt Length	Up to 4,000 characters	Up to 15,000 characters	Up to 4,000 tokens	Up to 8,000 tokens

Where Does Kling 4.0 Stand Out?

The comparison shows that no single model leads in every category.

Seedance 2.5 supports a wider range of voice languages and a larger prompt input capacity. Its Agentic workflow can also create longer sequences extending beyond a single generation.

Seedance 2.0 supports a broad set of aspect ratios, output options up to 4K, stereo audio, and multiple language workflows.

Kling 3.0 remains focused on cinematic short-form generation, native audio, multi-shot storytelling, and reference-based consistency.

Kling 4.0 pushes the Kling series further toward longer and more controllable video production.

Its combination of 30-second standard generation, native long-form video up to 120 seconds, 10-bit HDR at supported resolutions, dual-channel stereo audio, multi-keyframe control, multimodal references, and targeted editing makes it particularly relevant for projects where continuity and creative control matter.

For creators, the more useful question is therefore not simply which AI video model is best, but which model fits the project.

A short social clip, a multilingual campaign, a cinematic scene, and a two-minute narrative may each benefit from a different model.

Loova brings multiple premium video models into the same AI Video Generator, making it easier to compare different models and choose the right one for each project.

Why Kling 4.0 Matters More Than Longer Clips

It is easy to focus on “30 seconds” or “120 seconds,” but duration is only part of the story.

AI video models have already become good at generating impressive short moments.

The harder problem is producing a complete project.

Professional creators need more than one beautiful shot. They need:

Characters that stay recognizable
Environments that remain consistent
Camera movement that follows the story
Multiple scenes that feel connected
A way to fix one mistake without rebuilding everything
References that preserve creative intent
Longer narratives that do not feel stitched together

That is why the combination of features in Kling 4.0 is more interesting than simply increasing the maximum clip length.

Multi-keyframes provide structure.

Multimodal references provide context.

Long-form generation provides continuity.

Targeted editing provides iteration.

Together, these capabilities move AI video closer to a production workflow rather than a one-shot generator.

Viral Remix Could Be Big for AI Advertising

Kling 4.0 also introduces Viral Remix, a capability designed around using an existing video as more than a simple visual reference.

The reference can act as a creative blueprint.

Kling 4.0 can use elements such as:

Pacing
Shot changes
Camera transitions
Story structure
Creative rhythm

Creators can then combine those patterns with their own products, characters, environments, and other assets.

For marketers, this could be particularly useful.

A successful ad often works because of more than the product itself. Timing, hook structure, reveal, camera language, and scene progression can all influence the final creative.

Instead of manually rebuilding those structures, Viral Remix can help creators start from an existing creative format and adapt it to a different campaign.

That is especially relevant for:

Ecommerce
Fashion
Beauty
Consumer electronics
Performance marketing
Social creative testing

Once Kling 4.0 arrives on Loova, these capabilities can complement the Viral Ad Clone workflow inside Loova Ads Studio.

The distinction is important:

Viral Remix is a Kling 4.0 capability.

Viral Ad Clone is Loova’s structured workflow for adapting existing creative concepts to new products and campaigns.

Kling 4.0 for Short Films, Animation, Ads, and Music Videos

Short Films and Animation

Kling 4.0 looks particularly promising for story-driven video.

Longer generation, multiple keyframes, and richer reference inputs can help creators maintain characters, environments, and visual continuity across more complex sequences.

This is useful for:

Short films
Anime-inspired storytelling
Serialized content
AI animation
Character-driven projects

Creators can also use Loova Agentic Canvas to plan scenes, organize references, develop story structure, and build larger projects before moving into final video generation.

Music Videos

Music videos combine several of the areas Kling 4.0 is designed to improve:

Visual consistency
Timing
Character identity
Audio
Longer sequences
Targeted editing

Creators can combine portraits, style references, video clips, and audio within the same workflow.

Long-form generation and video extension can also help creators move beyond isolated visual loops and develop more connected music video sequences.

For dedicated music workflows, Loova also offers an AI Music Video Generator.

Ads and Ecommerce Videos

For ecommerce teams, Kling 4.0 could reduce the need to recreate every variation from scratch.

A product can remain the visual anchor while:

Backgrounds change
Camera movement changes
Characters change
Creative structures change
Markets change
Ad formats change

That makes the model especially relevant to teams producing high volumes of paid and organic video.

Loova Ads Studio provides structured workflows for turning products and campaign ideas into advertising creatives.

Not every project needs a 120-second story.

Kling 4.0 can also support content for:

TikTok
Instagram Reels
YouTube Shorts
Creator channels
Brand social accounts

Its combination of multimodal references, editing, and Viral Remix can make it easier to adapt one creative concept into several versions for different platforms.

For quick one-off generations and model testing, creators can use Loova’s AI Video Generator.

Kling 4.0 vs Kling 4.0 Flash

Kuaishou is also introducing Kling 4.0 Flash.

The two models are designed for different workflows.

Kling 4.0 focuses on higher-quality generation, precise control, and more complex storytelling.

Kling 4.0 Flash focuses on faster, more cost-efficient, higher-volume generation.

Feature	Kling 4.0	Kling 4.0 Flash
Best For	More controlled and complex creation	Fast, high-volume generation
Standard Duration	3–30s	3–20s

Creators working on filmmaking, brand campaigns, complex advertising, and longer storytelling may benefit from Kling 4.0’s additional controls.

For quick experiments, everyday social content, and higher-volume production, Kling 4.0 Flash is designed around a faster and more efficient workflow.

Multilingual Voice and Text Generation

Kling 4.0 is also designed for multilingual video creation.

The current model specifications include voice generation in nine languages:

Chinese
English
Japanese
Korean
Spanish
Portuguese
German
French
Hindi

It also supports selected dialects and accents, including Cantonese and Sichuanese, as well as American, British, and Indian English accents.

This can be useful for:

Global marketing
Ecommerce localization
International campaigns
Multilingual storytelling
Game characters
Branded content

Kling 4.0 also supports text generation across nine languages.

That can help creators generate visual text for:

Product packaging
Storefront signs
Subtitles
Advertising copy
In-scene graphics

For international brands, these capabilities could make it easier to adapt the same creative direction across several markets.

Kling 4.0 Is Coming Soon to Loova

Kling 4.0 is coming soon to Loova.

Once available, the model will become part of Loova’s broader AI video and image creation ecosystem rather than operating only as a standalone generator.

Creators will be able to choose different workflows depending on the project.

AI Video Generator

Use the AI Video Generator for quick generations, model testing, and one-off creative experiments.

Agentic Canvas

Use Agentic Canvas when a project involves multiple scenes, characters, assets, story planning, and creative iterations.

How to Prepare for Kling 4.0

Kling 4.0 is not publicly available on Loova yet, but creators can start preparing now.

1. Prepare Better Reference Assets

With support for richer multimodal references, asset quality becomes increasingly important.

Start organizing:

Character references
Product images
Style references
Environment references
Motion references
Existing footage
Audio assets

A clean reference library will make it easier to take advantage of more controllable generation once Kling 4.0 becomes available.

2. Start Thinking in Scenes, Not Just Prompts

AI video is increasingly moving away from:

Write one prompt and see what happens.

A more useful workflow is:

Opening → transition → key moment → action → ending.

That is where multiple keyframes and longer generation become more valuable.

Creators working on larger stories can already start structuring projects inside Agentic Canvas.

3. Build Reusable Characters and Brand Assets

Consistency becomes easier when projects begin with reusable references.

For creators, that could mean:

Character sheets
Costume references
Environment references
Style references

For brands, it could mean:

Product images
Brand environments
Mascots
Packaging
Visual identity references

These assets can then be reused across more scenes and campaigns instead of being recreated for every generation.

4. Test Your Ideas with Kling 3.0

You do not need to wait for Kling 4.0 to start developing ideas.

Kling 3.0 already supports cinematic video generation, native audio, reference-based workflows, and multi-shot storytelling.

Testing concepts now can help you identify:

Which prompts work
Which character references are strongest
Which visual styles are consistent
Which scenes need more control
Where longer generation would help

Those projects can then be revisited once Kling 4.0 becomes available.
