Kling 4.0 AI Video Generator
Kling 4.0 AI Video Generator turns a written prompt, a still image or a set of reference materials into a finished cinematic clip. Built on the Kling 4.0 model from Kuaishou, it produces anything from 3 to 30 seconds in a single pass and renders at 720p, 1080p or full 4K — wide enough for widescreen product films, square enough for social posts and tall enough for vertical shorts. What sets Kling 4.0 AI Video Generator apart from earlier video tools is Omni Reference: up to 15 reference assets — images, video clips, voice samples and subject elements — can be combined inside one workflow, while up to 10 keyframe images pin down the exact moments of a scene. Multilingual audio-visual synchronisation and two-channel stereo arrive together with the picture, so dialogue, lip movement and sound stay aligned without a separate audio pass. Everything runs in the browser: describe the shot, upload what you already have, then choose duration, resolution, aspect ratio and sound and generate. There is no timeline, no keyframing and nothing to install, which means a first clip takes minutes rather than hours. The same credit balance covers the whole workspace on this site, so Kling 4.0 AI Video Generator stays practical for short-form creators, advertising teams and studios exploring several directions before committing to a final shoot.
What Is Kling 4.0 AI Video Generator?
Kling 4.0 AI Video Generator is a free online video generator built on the Kling 4.0 model from Kuaishou. It reads what you describe — or what you upload — and returns a moving clip instead of a static frame: subject, camera movement, light and pacing are all produced for you. Give it a sentence and a reference image and it will hold the character, the product and the palette steady across the shot, because Omni Reference lets up to 15 assets be combined across images, videos, voice samples and subject elements. Up to 10 keyframe images can be placed to control how a scene opens, develops and closes, while multilingual audio-visual synchronisation and two-channel stereo are generated alongside the picture. Clips run from 3 to 30 seconds in one pass, and the export can be set to 720p, 1080p or 4K in 21:9, 16:9, 1:1, 9:16 or automatic framing. An existing video can be reworked as well: bring in up to five clips, one of them the primary take, and change an expression, a movement, a background or a style. Because everything happens in the browser, there is no editing suite to learn and no plugin to install. Kling 4.0 AI Video Generator is made for short-form creators, advertising and marketing teams, animation studios blocking out scenes, and developers sketching test cases — anyone who would rather describe the shot than build it frame by frame.
- Prompt, Image and Reference in One FlowThe generator accepts a text description, a still image, a video clip, a voice sample or a subject element as starting material. Mix whichever inputs match the brief and let the model assemble the motion — no separate text-to-video and image-to-video tools required.
- Omni Reference Holds the Subject SteadyUp to 15 reference assets can be combined on one project out of a single shared pool: ten images, five video clips totalling 30 seconds, or seven subject elements. That is what keeps a face, a product or a costume recognisable from the first frame to the last.
- Synchronised Multilingual AudioDialogue, lip movement and stereo sound are produced with the picture rather than bolted on afterwards, and voice references can guide how each character sounds. Longer scenes stay coherent because image and audio are generated together.
How to Use Kling 4.0 AI Video Generator
Three steps are all it takes: describe the shot, attach whatever references you have and choose the settings, then generate, review and extend when the scene needs more room. Everything happens online, no editing skill is involved, and the model does the animation work — so a finished clip is only minutes away.
Why Creators Choose Kling 4.0 AI Video Generator
Making video used to mean storyboards, motion design and long render queues. This tool collapses that into a single pass: the scene is generated from your description and your references, the audio arrives with the picture, and the result stays editable before export. Compare a few directions, keep the phrasing that works, and leave with a clip worth publishing.
Clips Up to 30 Seconds in One Pass
As much as 30 seconds can be produced without stitching separate renders together. That is enough room for an opening, a main action and an ending — and when a story needs more, the scene can be extended by describing what happens next.
720p, 1080p and 4K Output
Pick the resolution that matches the delivery, from fast 720p social drafts through to 4K masters, and frame the shot in 21:9, 16:9, 1:1, 9:16 or automatic ratio. Wide product films and vertical shorts come out of the same workflow.
Omni Reference Across Four Input Types
Up to 15 reference assets can be combined — ten images, five video clips within 30 seconds, seven subject elements, plus voice samples — all drawing on one pool. Subject shape, colour and branding survive the whole sequence.
Up to 10 Guiding Keyframes
Keyframe images define the moments that matter: how a scene opens, how a character changes, how it closes. As many as ten can be placed across a 3 to 30 second clip, with subject and lighting held consistent between them.
Video Editing Without a Timeline
An existing clip can be reworked using up to five input videos, one of them primary, each 3 to 30 seconds and 30 seconds combined. Change an expression, a movement, a background or a style and leave the rest of the take intact.

Kling 4.0 AI Video Generator — Frequently Asked Questions
Answers on what this video generator does, how long its clips run, whether it outputs 4K, how Omni Reference works, whether existing videos can be edited, and where the tool can be used.
What is Kling 4.0 AI Video Generator?
It is an AI video model from Kuaishou, delivered here as a browser-based generator. Describe a scene or upload a reference and it returns a 3 to 30 second clip in 720p, 1080p or 4K, with multilingual synchronised audio, stereo sound, up to 15 Omni Reference assets and up to 10 guiding keyframes.
How long can a clip be?
Between 3 and 30 seconds in a single generation. Extending a scene is a separate step rather than one long render, so treat an extended sequence as several passes joined together and check the joins before delivery.
Does it output 4K?
Yes — 720p, 1080p and 4K are all supported, subject to the mode you select. Resolution and HDR are independent settings, so confirm which export options are available for the delivery you have in mind.
How does Omni Reference work?
Up to 15 reference assets can be used at once, drawn from images, video clips, voice samples and subject elements. The category caps — ten images, five clips within 30 seconds, seven subject elements — share that single total rather than stacking on top of it.
Can I edit an existing video?
Yes. Up to five input clips can be supplied, one of them the primary take, each between 3 and 30 seconds with a combined ceiling of 30 seconds. Choose whether the expression, the movement, the background or the style should change.
Do I need editing or prompt-writing experience?
No. Write the scene in ordinary language, attach whatever references you have and generate. There is no timeline to learn and no keyframes to place by hand, and the audio is produced with the picture rather than mixed separately afterwards.
Generate Cinematic Video with Kling 4.0 AI Video Generator
Take an idea from a sentence to a finished clip: describe the shot, add the references you have, and generate up to 30 seconds in 4K with synchronised audio. Review the draft, extend it when the scene needs room, then download and publish. Open the generator and write the scene you want to see.
