What Is Kling 4.0?

Kling 4.0 (可灵 4.0) is the newest generation of Kling AI's video model from Kuaishou, announced on September 28, 2026. It aims for realistic motion, precise control and complete stories, and it fits the way creators actually work — begin with a prompt, an image or your own references. Kling 4.0 Flash, a faster 720p version, is already in early access, and the full model launches in October 2026.

Text to Video

Describe a scene and Kling 4.0 builds it from scratch: characters, motion, camera work and sound in one pass. Native 30-second generation leaves room for a whole story beat — setup, turn and payoff — without stitching clips together.

Image to Video

Start from a photo, a product shot or a storyboard frame. Add as many as 10 keyframe images to pin down poses, scene changes and story beats, and Kling 4.0 animates the motion between them.

Reference to Video

Omni Reference combines up to 15 inputs in one request — images, video clips and elements with voice — so faces, products, motion and camera moves stay consistent from shot to shot.

Kling 4.0 AI Use Cases

See how reference-driven AI video works in practice. Each demo shows its inputs, the result and the mode it uses — the same workflows Kling 4.0 AI is built for in ads, brand campaigns, e-commerce, short dramas and music videos.

Reference to Video

Creative Templates & Outfit Changes

Recreate fisheye lenses, flash overlays and outfit swaps while the model's face stays the same across every cut. With Omni Reference, a whole lookbook can become one continuous fashion film.

Make a Lookbook Video

“Reference the model's face from image 1. The model walks toward the camera wearing the outfits from reference images 2–6, striking playful, cool, cute, surprised and stylish poses. Each outfit change triggers a cut using the fisheye lens and flash overlay from the reference video.”

Reference to Video

Motion & Camera Replication

Take character motion from one video and camera movement from another, then combine them into an epic fight under a starry sky. Because Kling 4.0 reads several reference videos at once, motion and camera can come from separate sources.

Copy a Camera Move

“Reference the character motion from video 1 and the orbiting camera movement from video 2. Generate a fight between character 1 and character 2 under a starry night sky, with white dust rising during the fight. The battle feels spectacular and intense.”

Video Extension

Keep the Story Going

Extend a clip while keeping characters and backgrounds consistent — here, a donkey on a motorcycle races through a playful ad. Kling 4.0 can extend video forward or backward from the clip you already have.

Extend a Clip

“Using @image1 and @image2 of the donkey on a motorcycle, extend the video. Scene 1: side shot of the donkey bursting through a fence and startling chickens. Scene 2: the donkey doing motorcycle stunts on sand, tire close-up, then an aerial shot. Scene 3: the donkey jumps against a mountain backdrop and the text "Inspire Creativity, Enrich Life" is revealed through a masking effect.”

Image to Video

Cinematic Audio & Visuals

Start from one storyboard image and use precise cinematography keywords to get music-video quality: golden-hour light, film grain and hero framing. Kling 4.0 accepts prompts of up to 8,000 tokens, so lighting, lens, composition and color can each get their own instructions.

Animate a Storyboard

“Generate a music video. Keywords: stable composition, smooth push-pull, low-angle hero shot, premium documentary feel. Ultra-wide establishing shot tilted slightly upward, a vintage road-trip car on a cliffside dirt road in the lower third, distant sea and horizon for depth, sunset back-side light with volumetric rays through dust, cinematic framing, authentic film grain, clothes moving gently in the wind.”

Video Editing

Character Swap That Keeps the Motion

Replace a character while keeping the original motion intact — the band keeps playing while the lead singer changes. Kling 4.0 edits expressions, actions, camera, style or background in an existing video without regenerating the whole clip.

Swap a Character

“Replace the female lead singer in video 1 with the male singer from image 1. Motion must match the original video exactly. No camera cuts. The band keeps playing.”

Image to Video

One-Take Long Shot

Build a seamless one-take sequence from several reference images, following a runner from the street up the stairs, through a hallway and onto a rooftop. Each image works like a keyframe, so every location becomes a beat Kling 4.0 hits in order.

Plan a Long Take

“@image1 @image2 @image3 @image4 @image5, one-take tracking shot following a runner from the street, up the stairs, through a hallway and onto the rooftop, ending on a view of the city.”

Reference to Video

Creative Story Completion

Give the model a few images and a soundtrack and let it complete an emotional story. Sound is generated together with the picture, so the music and the edit land on the same beat.

Tell a Story with Sound

“Use the audio from video 1 to create an emotional video inspired by images 1–5. Reference @video1 for the background music.”

Create a Kling 4.0 AI Video in 3 Steps

Whether you start from text, a single image or a stack of references, the Kling 4.0 AI workflow stays the same.

Choose How to Start

Use text to video when all you have is an idea, image to video when you have a still or keyframes to animate, and reference to video when you want to combine photos, video clips and a voice sample.

Write the Prompt

Describe the scene, then use @ mentions to tell the model what each asset is for — for example "use @image1 as the character and @video1 for the camera move".

Generate & Refine

Choose the length and aspect ratio, then generate. Extend the clip or edit specific details instead of starting over.

Look what came out of the video I made with text-to-video in Kling 4.0 😅 No TV show or actor name appears anywhere in the prompt.

What stood out to me most wasn’t just the image quality, but its ability for lipsyncing! Shaky handheld camera actually felt shaky. The anamorphic lens look came through.

Two characters, continuous acting, emotional dialogue, natural motion, and a convincing British accent all held together across the full shot. And this is only the Flash model.

Kling 4.0 is amazing! It blends multiple references well, action scenes and camera work are stronger, Japanese got better, and it generates 30 seconds at once — I made a 4-minute video in no time.

For photoreal video Kling is a head above the rest. A 5-second clip cost under ¥50 — about 1/5 of Seedance 2.5 — and generation is blazing fast. If Flash looks this good, the full 4.0 will be something.
