Up to 30 Seconds From One Prompt

Kling 4.0 renders up to 30 seconds in a single generation, twice the length of Kling 3.0 and long enough for a scene to build, escalate and resolve. Write one unbroken take or plan several shots with cuts; Kling follows the structure your prompt sets out.

In Kling’s demo below, two reference images fix the burning city and the dragon, and the prompt times six shots, from the roar on the mountain pinnacle to the climb above the flames.

Up to 30 Seconds From One Prompt – Kling 4.0 — Prompt (abridged): A 30-second, six-shot dark-fantasy action sequence. A colossal dragon roars, launches from a mountain pinnacle, accelerates toward a burning coastal city, dives between its towers and performs a devastating aerial fire attack. SHOT 1 — 0.0–4.0s: roar and launch. SHOT 2 — 4.0–9.0s: high-speed pursuit toward the harbour. SHOT 3 — 9.0–13.5s: low flight across the water toward the city. SHOT 4 — 13.5–19.0s: first fire attack between towers. SHOT 5 — 19.0–25.0s: banking pursuit and sweeping fire attack. SHOT 6 — 25.0–30.0s: dragon climbs above the burning city. (Kling 4.0 · 16:9 · 30s)

Open and Close on the Frames You Choose

Upload the picture the clip should start on and, if you want, the one it should end on. Kling 4.0 keeps the look of both and works out the motion, the camera path and the sound in between, across as much as 30 seconds.

Yovid sends the run to Kling’s image-to-video route as soon as a frame is attached, and the clip takes its shape from your first frame. Here a café street opens the shot, a crowd closes it, and a 20-second lateral tracking chase fills the middle.

Copy the Action From a Reference Clip

A reference video gives Kling 4.0 what words struggle to describe: the exact rhythm of a fight, a dance or a stunt. Add up to 5 clips, 30 seconds in total, next to up to 10 images, and say in the prompt what each one is for. On Yovid every upload gets a tag such as @Image 1 or @Video 1 to type into the prompt.

In this demo Kling took the punches and their timing from a boxing match and the two fighters from character sheets, and staged the bout in a new setting.

Copy the Action From a Reference Clip – Kling 4.0 — Prompt (abridged): Use @Video 1 as the reference for the fight choreography and attack timing. Use @Image 1 and @Image 2 as the references for the character designs. (Kling 4.0 · 16:9 · 7s)

Follow the Camera Path of Any Clip

Kling 4.0 reads push-ins, pull-outs, pans, tracking shots and orbits from a reference clip, so a drone pass or a chase shot you like can become the template for something else entirely.

Here a drone circling a car on a salt flat sets the camera path and pacing, four product views supply the race car, and a single image supplies the night arena.

Follow the Camera Path of Any Clip – Kling 4.0 — Prompt (abridged): Use @Video 1 as the reference for camera movements and shot pacing. Replace the Element with the car from @Image 1 and the background with @Image 2. (Kling 4.0 · 16:9 · 7s)

Storyboards and Character Sheets as References

Reference images are not only faces and products. Kling 4.0 also reads storyboards, three-view character sheets, grids and wireframes, so planning work you already have can steer the generation directly.

This 15-second claymation follows an eight-panel storyboard beat by beat in one continuous camera move, while the character sheet keeps the terrier, his spacesuit and his oversized fork the same in every frame.

Storyboards and Character Sheets as References – Kling 4.0 — Prompt (abridged): Strictly follow the attached storyboard (Image 1) as the basis, adhering to the shot order, composition, camera movement paths and emotional progression. The attached character design sheet (Image 2) is the sole authoritative reference for BISCUIT: a small, round, plump clay terrier in a tiny white clay spacesuit, holding a clay fork larger than himself. Duration: 15 seconds, aspect ratio 16:9. The entire sequence must be one continuous master shot with no visible cuts. Visual style: handcrafted clay stop-motion animation with visible fingerprints and clay textures. A yellow cheese moon riddled with holes, and Earth in the sky. (Kling 4.0 · 16:9 · 15s)

Dialogue in Nine Languages, Lips in Sync

Every Kling 4.0 clip comes with stereo sound generated alongside the picture: dialogue, effects, ambience, and music when you ask for it. Kling lists Chinese, English, Japanese, Korean, Spanish, Portuguese, German, French and Hindi for speech, plus accents such as British or Indian English and dialects such as Cantonese.

In this demo a tourist asks the way in Spanish, an interpreter relays it in Chinese and back, and each of the three speakers keeps a distinct voice with lips matched to the language.

Dialogue in Nine Languages, Lips in Sync – Kling 4.0 — Prompt (abridged): Three people are in a bright, clean city tourist information center: the tourist on the left, the interpreter in the middle, the tourism staff member on the right. The Spanish female tourist raises the map in her hand and speaks in natural, clear, slightly slow Spanish: “¿Dónde está la estación de metro más cercana?” The interpreter turns to the staff member and translates into Chinese: “她想知道最近的地铁站在哪里。” The staff member answers in Chinese: “沿这条路直走，步行大约五分钟就能到。” The interpreter translates into Spanish: “La estación de metro está a unos cinco minutos a pie. Siga recto por esta calle.” The tourist smiles and says: “Muchas gracias.” Each person has a distinct voice, with lip movements synchronized to the language. (Kling 4.0 · 16:9 · 15s)

Who Kling 4.0 Works Best For

Thirty seconds per take, references for cast and camera, and an ultrawide frame make it a strong fit for these jobs:

Ad and brand teams: A product, a model and a location from your own photos, staged together in one 30-second spot without a reshoot.
Short-drama and story makers: Longer scenes that build, turn and land in one take, with the same characters held by reference images across episodes.
Filmmakers and previs artists: Camera moves copied from a reference clip, and 21:9 ultrawide framing for widescreen pitches and storyboards.
Social and short-form creators: Vertical 9:16 clips long enough to tell a whole beat, from a prompt or from a still you already posted.
E-commerce and product teams: A product photo as the first frame and a packshot as the last, with the move between them generated in 1080p.

Strengths and Limits of Kling 4.0

Where it earns its place in the lineup on Yovid, and where another model or setting is the better call.

Strengths

Length: Up to 30 seconds in one generation, twice Kling 3.0’s 15, with sound included.
References: Up to 10 images and 5 clips per run, called by name in the prompt.
Framing: 21:9 ultrawide next to 16:9, 9:16 and 1:1, at 720p or 1080p.
One model, three routes: Text, frames or references in the same picker; Yovid switches Kling’s endpoint for you.

Limits

Resolution: Stops at 1080p on Yovid; Kuaishou has announced 4K and 10-bit HDR but they are not available here. Kling 3.0 renders 4K.
Keyframes and editing: Yovid takes a first and a last frame only, not Kling’s in-between keyframes, and has no Kling 4.0 edit or extend mode; use Seedance 2.5 to edit or extend a clip.
Reference clips cost more: A run with a reference video bills the output plus the longer of the clips or the output, so it often costs more than a text run.
Plan access: Not on the free plan; Lite and above, or a Creator credit pack or larger, unlocks it.

Reunion on a UK street
Text only · 7 s
A continuous 7-second shot set in the UK. Two friends who have not seen each other for a long time meet at the corner of a quiet street at dusk, surrounded by a diverse crowd going about their daily lives. They smile, walk quickly toward each other, and share a warm embrace. Their facial expressions and body movements are natural. A handheld camera follows them with subtle camera shake. Soft, warm lighting with a nostalgic cinematic film look. Include natural footsteps, street ambience, background music, and English dialogue.

Street escape in one take
First + last frame · 20 s
Generate a 20-second, horizontal 16:9 realistic cinematic street escape video. The entire video must be one continuous lateral side-tracking long take, filmed in a single shot with no cuts. The scene takes place on a busy Manhattan-style street with outdoor restaurant seating, yellow taxis, newspaper stands and white steam rising from subway grates. The camera moves laterally to the left while following a young woman running with a large, heavy travel bag that thuds against her leg. A taxi briefly blocks the view, the camera loses her and finds her again, and she finally disappears into the crowd at the entrance to a pedestrian street.

Biscuit on the cheese moon
Storyboard + character sheet · 15 s
Strictly follow the attached storyboard (Image 1) and use the character design sheet (Image 2) for BISCUIT, a small clay terrier in a white spacesuit holding a fork larger than himself. 15 seconds, 16:9, one continuous master shot with no cuts, in handcrafted clay stop-motion style. Biscuit hops across a wobbling cheese moon, falls through a hole past a giant clay cheese mouse, is chased back out, takes a blissful bite of cheese midair, and ends sitting beside the mouse as Earth rises.

FAQs

What is Kling 4.0?

Kling 4.0 is the video model Kuaishou’s Kling AI launched on October 15, 2026. It renders up to 30 seconds in a single pass, holds large-scale motion and camera moves together, and takes a mix of images, videos and subjects as references. Yovid runs it in the browser next to Seedance, Wan, Veo, MiniMax and other models.

How long can a Kling 4.0 video be?

Anywhere from 3 to 30 seconds per generation on Yovid, set with a slider; the default is 5 seconds. A clip can be one unbroken take or several shots with cuts, depending on how you write the prompt.

Can I use Kling 4.0 for free on Yovid?

Signing up is free and includes credits you can spend on the free-plan models. Kling 4.0 itself is unlocked on the Lite plan and above, or with a Creator, Studio, Max or Agency credit pack. Exports carry no watermark.

How many credits does a Kling 4.0 video cost?

At credit-pack base rates it is 3 credits per second at 720p and 5 at 1080p, so a 5-second 720p clip is 15 credits and a full 30-second 1080p take is 150. With a reference video the rate drops to 1.8 and 3 credits per second, charged on the output plus the longer of the reference clips or the output. Subscribers pay less per second, and the composer shows the exact figure before you generate.

Does Kling 4.0 generate sound?

Yes. Every clip comes with stereo sound generated alongside the picture: dialogue, effects, ambience, and music when the prompt asks for it. There is no switch to turn it off, and it costs nothing extra. Write each line after the character who says it, with the language and tone, and Kling 4.0 voices it with matching lip movement.

How do reference images and videos work?

Upload up to 10 images and 5 clips as references. Each upload gets a tag, @Image 1 or @Video 2, that you type into the prompt to say what it is for: who the character is, what they wear, where the scene is, or which camera move to follow. Reference clips must be at least 3 seconds each and 30 seconds in total.

Can I turn an image into a video with Kling 4.0?

Yes. Attach an image as the first frame, and optionally a second image as the last frame, then describe the motion. Yovid switches to Kling 4.0’s image-to-video route automatically, and the clip takes its shape from your first frame.

Does Kling 4.0 support 4K or HDR on Yovid?

Not yet. Kuaishou has announced 4K, 10-bit HDR and two-minute extensions for Kling 4.0, but the version available to Yovid renders 720p or 1080p. For 4K, use Kling 3.0, Seedance 2.0 or Veo 3.1 Fast.

Which aspect ratios does Kling 4.0 support?

16:9, 9:16, 1:1 and 21:9 ultrawide for text and reference runs. An image-to-video run follows the shape of your first frame.

Can I use Kling 4.0 videos commercially?

Commercial use is included on Pro, Premium, yearly plans and one-time credit packs; Lite monthly does not include it. Exports carry no watermark. You remain responsible for the rights to your prompts, frames and references, including faces, brands and music.
