What Is Kling 4.0?
Kling 4.0 is the next generation of Kling’s video model family, focused on connected storytelling, multimodal references, and more control over how a shot unfolds.
The announced model targets videos up to 30 seconds and output up to 4K. Reference assets and keyframes help describe subjects, environments, motion, and the progression between important moments.
Use this page to understand the announced model and prepare your creative brief. The tool above keeps ReelMuse’s existing model list; choose a connected model and its supported settings to create a video today.
Official Kling 4.0 release notesWhat’s New in Kling 4.0?
These are announced Kling 4.0 capabilities. Access, limits, and rollout can differ between the official product and API providers.
Longer scenes with a clear story arc
Up to 30 seconds gives an action more room to develop: establish the subject, build the movement, and finish on a deliberate reveal. Plan the beginning and end before adding more events.
Output up to 4K
Higher resolution can help product details, fabrics, and environments read more clearly. Composition and source quality still matter; resolution alone does not fix a weak creative brief.
Omni Reference for a richer brief
The announcement describes up to 15 reference assets. Use each asset for a purpose, such as character appearance, location, style, or motion, instead of repeating the same information.
Up to 10 keyframes
Keyframes can express the visual states that guide a sequence. Keep the subject recognizable and make transitions achievable rather than asking unrelated images to become one continuous take.
Motion, performance, and sound
The release material highlights complex motion, lip-sync, and stereo sound. Give each speaker or action a clear role, and review the generated performance through the whole clip.
Targeted edits and readable visual details
The model direction also emphasizes video editing, multilingual text, logos, and visual consistency. Exact lettering and identity still need review before a result is published.
From Reference Assets to Finished Video
Explore nine examples with their matching reference images or motion guides. Open a reference image for a closer look, then play the result to compare composition, character appearance, and movement.
Woodland characters and their world
Forest scenery, mouse and hedgehog character sheets, and a shared scale reference are paired with an animated woodland scene.
One character across interior scenes
Room views and a character sheet provide separate guidance for the setting and the performer in the resulting interior sequence.
A storyboard becomes animation
Character artwork and a storyboard describe the look and sequence of an animated space adventure. Compare the planning images with the finished clip.
A movement guide plus character references
A simple white-model video supplies movement guidance, while character sheets describe appearance. The result turns the brief into a rendered walking scene.
A sketch becomes a visual composition
Two simple drawings lay out the subject and a large lotus form. The video explores that composition as an illuminated fantasy scene.
Depth guidance for a character performance
A depth-style movement reference and a portrait guide a vertical clip. Compare the pose structure with the visible character performance.
Two characters in a martial-arts scene
Separate full-body references introduce the performers. The result brings the pair into a shared action scene with a different environment.
Keyframes guide a changing scene
A board of visual moments lays out transitions between a hand, objects, and interior imagery. Play the clip to see how those states connect.
Element removal in a street performance
A source clip and an edited result show a targeted change in a crowded street-performance scene. Review the people and surrounding background side by side.

How to Create with the Current Video Tool
Use the same input, settings, credits, and result workflow as the other ReelMuse video tools.
- 01
Choose the input that carries your idea
Start with Text to Video for a new shot, Image to Video for frame guidance, or Video to Video for transformation. The latter needs a source clip and reference image.
- 02
Describe one shot and choose settings
Write the subject, action, environment, and camera movement. Use the duration, resolution, and aspect ratio actually offered by the selected model, then check the displayed credit cost.
- 03
Generate, review, and refine
Your task opens in Generate after submission. Watch the full clip, download the completed result, and change one detail at a time when you want another version.
Kling Video Prompts You Can Start With
Use these original prompts as a starting point in the video tool. Choose a model that accepts your inputs, then adjust the action and camera movement for the duration you select.
A product reveal
Keep the product readable while giving the shot a clear beginning and closing position.
PromptA matte ceramic perfume bottle stands on warm stone. The camera slowly arcs around it as soft side light reveals the texture. Keep the bottle shape consistent and finish with a steady front view. No on-screen text.
A character moment
Use a source image when appearance and composition should guide the result.
PromptA woman in a cream coat pauses at a rain-streaked window, notices the morning sunlight, and gives a small smile. A slow camera push-in, natural proportions, subtle movement, and soft reflected light.
An animated scene
Choose one action and a restrained camera move before adding more story beats.
PromptA small fox walks through a hand-painted woodland, stops beside a glowing flower, and leans forward to inspect it. Gentle tracking camera, consistent character design, warm evening light, and smooth restrained animation.

Kling 4.0 Questions
Direct answers about the model announcement, existing video tools, prompts, pricing, and access.
- 1
Is native Kling 4.0 available on ReelMuse?
Not yet. This page introduces Kling 4.0, while the generator keeps the existing model list. Choose a connected model to create a video; native Kling 4.0 integration will be a separate update.
- 2
What is the difference between Kling 4.0 and Flash?
The announced standard model targets 3–30-second videos at up to 4K. Flash is positioned for frequent creation with 3–20-second output at 720p. Check the official release notes for current access and rollout details.
- 3
Can I generate 30-second videos or upload 15 references here?
Those are announced Kling 4.0 capabilities. The current tool follows the limits of the model you select. Use the duration controls and upload requirements shown in the generator; model information on this page does not unlock unsupported settings.
- 4
Can I create videos from text, images, or a source video?
Yes. The existing tool offers those three workflows through supported models. Start from text for a new scene, use images for visual guidance, or select a video transformation model with its required reference media.
- 5
How should I write a Kling video prompt?
Name the subject, one main action, the setting, and one camera movement. If you add a reference, explain its role. Keep appearance and motion instructions compatible, and change one detail at a time when refining a result.
- 6
Is Kling 4.0 free on ReelMuse?
Native Kling 4.0 pricing has not been set here. Connected models use the credit cost shown before generation. Eligible free credits can contribute if your balance covers it; the plans and credit packs below fund currently available tools.
- 7
Are all announced sound and editing features enabled here?
No. Sound, frame guidance, and video editing depend on the connected model you select. Review its available inputs and settings. Announced Kling 4.0 upgrades remain model information until a supported integration is added.
- 8
Where can I download videos or check official availability?
Open your completed task in Generate to download or share it. Use the official Kling 4.0 release notes linked on this page for the latest native-model availability; access can differ by account and provider.
