What is Kling 4.0?
Kling 4.0 is Kuaishou's newest AI video model. It turns a text prompt, a photo, or a first and last frame into one continuous take of up to 30 seconds at 720p or 1080p. On Imgveo it costs 29 credits per second at 720p, and failed clips are refunded.
Kling 4.0 arrived in October 2026, about eight months after Kling 3.0. The headline change is length: a single generation now runs twice as long, so a scene can build, turn and land without stitching clips together.
Kling 4.0 Flash is the lighter version of the same model, made for quick 720p drafts. Test an idea there, then move the prompt to Kling 4.0 for the final take.

Twice the length in one take
Kling 3.0 stopped at 15 seconds. The new model runs to 30, so a slow reveal or a full product turn fits in one generation, with one consistent look from the first frame to the last.
Keyframes, not just two frames
Kuaishou's own app accepts up to 10 keyframes per take. On Imgveo you set the first and the last frame today, and the model fills in everything between them.
More references at once
The model can read up to 15 reference images, clips, elements and voices in a single request, which helps keep a character the same across a long take.
Stereo sound and sharper lip sync
Kuaishou says the new model renders two-channel sound and matches lip movement more closely than Kling 3.0, in more languages.
HDR and a 21:9 frame
It adds a cinematic 21:9 ratio, which you can pick on Imgveo for text-to-video. Kuaishou also lists 10-bit HDR at 1080p and 4K.
Kling 4.0 or Kling 4.0 Flash?
Both run on Imgveo. Pick by length, resolution and budget, and keep Kling 3.0 in mind when you need native 4K.
Kling 4.0
For final takes: up to 30 seconds at 1080p, with a first and last frame to pin where the shot begins and ends.
5 s at 720p: 145 credits
Kling 4.0 Flash

Kling 3.0
For native 4K, or a cheaper 720p take of 15 seconds or less when length doesn't matter.

How to make a Kling 4.0 video in 3 steps
No editing software and no setup: the generator at the top of this page does the whole job.
01
Choose how to start
Write a prompt, upload one photo as the first frame, or upload a first and a last frame. Then pick the full model or Flash.
02
Describe the shot
Lead with the camera, then the subject and what happens. For a long take, say what changes along the way and how the shot ends.
03
Set the length and generate
Choose 720p or 1080p and 5 to 30 seconds; the button shows the exact credits. Download the MP4 when it's ready, with no watermark.
The Bookend Method: first and last frames in Kling 4.0
A long take drifts when the model has to guess where it ends. Give it both ends and it only has to plan the journey between them. We call this the Bookend Method.
Illustration
IllustrationA bud opens in one still shot
Prompt: One continuous static close-up on the windowsill: the hibiscus bud slowly opens into a full pink flower, the morning light stays the same, leaves move slightly in a breeze
Illustration
IllustrationDawn to night on one street
Prompt: One continuous locked-off wide shot of the street: the sky moves from dawn to night, the shops open and light up, people gradually fill the pavement, reflections grow on the wet stones
Three rules for frames that connect
01
Plan the last frame first
Decide where the shot has to land, then work backwards. A clear ending gives every second before it a direction.
02
Keep the camera and the light
Make both frames from the same angle, lens and light. The model can then spend its effort on the change instead of reconciling two different pictures.
03
Write the journey, not the frames
Your frames already show the start and the end. Use the prompt for what happens between them: the order of events, the pace, and anything that should stay still.
Quick tips
Same ratio for both frames
The video takes the first frame's aspect ratio, so give the last frame the same one.
One big change per take
A flower opening or a day turning to night reads clearly. Five changes at once look like a jump cut.
More seconds for bigger changes
Give a large transformation 10 to 15 seconds. A small one looks natural at 5.
Ask for one continuous shot
Writing “one continuous shot” helps the model avoid cutting between your two frames.

A prompt formula for 30‑second Kling 4.0 shots
Kuaishou's own advice is to lead with the camera and describe each beat. This four-part order turns that into a habit.
- 01
Camera
Shot size and movement first: wide, close-up, tracking, locked-off or aerial.
- 02
Subject
Who or what is on screen, with two or three concrete details.
- 03
Beats
What happens, in order. Plan one beat for every 5 to 10 seconds of the take.
- 04
Ending
How the shot lands: a final pose, a reveal, or the camera settling.
Four templates to copy
Replace the words in brackets. Each template is written for the length shown.
Product reveal
Text to video · 16:9 · 10 s
[Slow orbit shot]: a [product] on a [surface], [lighting]. The camera circles once as [detail] catches the light. Ends on a close-up of [feature].
Travel reveal
Text to video · 21:9 · 15 s
[Aerial drone shot] over [place] at [time of day]. The camera flies toward [landmark] while [weather detail] drifts through the frame. Ends with the camera rising above [landmark].
Character from a photo
Image to video · 9:16 · 10 s
[Medium shot]: the person in the photo [action] in [setting]. Halfway through, they [second action]. Ends as they [final pose], the camera holding still.
30-second long take
Text to video · 16:9 · 30 s
[One continuous tracking shot]: [subject] [first beat]. Then [second beat]. Then [third beat]. Ends with [final image], [lighting] throughout.
Three mistakes to avoid
01
Describing a still photo
“A beautiful beach at sunset” gives the model nothing to animate. Add what moves and how the camera behaves.
02
Cramming cuts into one take
The model makes one continuous shot. Asking for “then cut to” three times usually produces morphing instead of edits.
03
Paying for 30 seconds of nothing
If your idea has one beat, a 5-second clip says it. Save the long takes for shots that genuinely develop.
Kling 4.0 price: credits per clip
You pay per second of video. Every number below comes from the same code that prices the generator.
| Length | 720p | 1080p | Flash 720p |
|---|---|---|---|
| Per second | 29 | 43 | 17 |
| 5 seconds | 145 | 215 | 85 |
| 10 seconds | 290 | 430 | 170 |
| 15 seconds | 435 | 645 | 255 |
| 20 seconds | 580 | 860 | 340 |
| 30 seconds | 870 | 1,290 | — |
credits
How the price works
Credits = seconds × the per-second rate. A 10-second 1080p clip costs 430 credits; the same length on Flash at 720p costs 170.
What a plan buys
The Starter plan's 1,500 monthly credits cover about 10 five-second 720p clips on Kling 4.0, or 17 on Flash.
Failed clips are refunded
If a generation fails, the credits go back to your balance automatically. You only pay for the videos you receive.
