Kling AI — motion, by the second.
Kling from Kuaishou is the value pick for movement: fluid human motion, believable weight, and the widest choice of clip length in King AI's catalog. Kling V3 Pro generates any whole number of seconds from 3 to 15 at 1080p, which means you pay for the length the shot needs instead of rounding up to a fixed tier.
Specs
What Kling V3 Pro actually does.
Every figure below is read from the app's own model catalog at build time, so it is the number you will be charged — not a rounded marketing estimate.
| Mode | Engine | Max resolution | Clip length | Audio | Credits |
|---|---|---|---|---|---|
| Text to video, V3 Pro | Kling V3 Pro | 1080p | 3–15s | Yes | 1.68 per second (~$0.67) |

Strengths
What Kling V3 Pro does best.
The motion king — fluid, physical movement at unbeatable value.
Length priced by the second
Three to fifteen seconds, one second at a time. No other family in this line-up lets you buy exactly eleven seconds.
Fluid motion
Dance, sport, combat, walking — movement that stays on model frame to frame, which is what the family is known for.
Under half the price of Veo
Kling V3 Pro fills a second of 1080p for 1.68 credits, against 4 for Veo 3.1 — under half the price, for clips nearly twice as long.
Start and end frame
Give Kling an opening and a closing image and it generates the motion between them, so a transition lands exactly where the edit needs it.
Limits
Where Kling is the wrong pick.
No model wins every shot. These are the cases where something else in the app is the better spend.
4K is a different price. Kling V3 4K and Kling O3 4K generate at 4K from a prompt or a still, but they bill 4.2 credits a second against 1.68 for V3 Pro — two and a half times the rate — so a 15-second 4K take is 63 credits. Draft at 1080p and re-run only the keeper at 4K.
Length is the price, and a cheap second is not a cheap clip: 15 seconds of Kling V3 Pro costs 25.2 credits, 5 times the 3-second version at 5.04. Decide the length before you decide the model.
Seven Kling tiers sit in the picker — V3 Pro, V3 Standard, V3 Turbo Pro, V3 4K, O3 Pro, O3 Standard and O3 4K — and they are easy to confuse. The specs table above is the one place the ones that matter are laid out side by side.
Head to head
Kling V3 Pro against the alternatives.
The same six columns for the models you would realistically pick instead, on the same job.
| Model | Max resolution | Clip length | Audio | Credits per second | Shortest clip |
|---|---|---|---|---|---|
| Kling V3 Pro | 1080p | 3–15s | Yes | 1.68 (~$0.67) | 3s · 5.04 credits (~$2.02) |
| Kling V3 Standard | 1080p | 3–15s | Yes | 1.26 (~$0.50) | 3s · 3.78 credits (~$1.51) |
| Veo 3.1 | 1080p | 4s·6s·8s | Yes | 4 (~$1.60) | 4s · 16 credits (~$6.40) |
| Seedance 2.0 | 1080p | 4–15s | Yes | 6.804 (~$2.72) | 4s · 27.22 credits (~$10.89) |
Best for
Where to use Kling V3 Pro.
Every card links to the King AI tool that gets you there fastest.
People in motion
Dance, fitness and action, where limbs have to stay attached between frames.
Photo animation
The default choice for animating a portrait or a product still.
Start and end frame
A defined opening and closing image with generated motion between.
Volume content
Daily social output, where the cost of the third re-roll decides the workflow.
How it works
Getting the most out of Kling V3 Pro.
Pick the exact length
Kling bills whole seconds from 3 to 15 at 1.68 credits each. Choosing 7 seconds instead of 8 saves 1.68 credits, and it repeats on every re-roll.
Use Standard while you iterate
Kling V3 Standard is the same family at a lower per-second rate. Explore there, deliver on Pro.
Give it an action, not an adjective
Kling responds to what the subject does. 'She turns and walks toward the camera' beats 'a beautiful cinematic scene'.
Reach for start and end frame
When you already know how a shot begins and ends, supplying both images is more reliable than describing the motion.
Prompts
Three prompts that play to Kling V3 Pro's strengths.
Written for this engine, not swapped between pages. Each one opens the studio with Kling V3 Pro selected and the prompt already in the box — the cost shown is what one clip at the shortest length it offers will take off your balance.
Human motion
“A breakdancer drops into a windmill on wet concrete as a train passes behind, spray lifting off the ground with every rotation. Low angle, 50mm, camera tracking with the body.”
3s · 5.04 credits (~$2.02)
Generate on Kling V3 Pro →Weight and physics
“A goalkeeper dives full stretch across the frame, fingertips just clipping the ball, mud spraying off the studs, crowd blurred behind. Side-on tracking shot, overcast stadium light.”
3s · 5.04 credits (~$2.02)
Generate on Kling V3 Pro →Eleven seconds, not twelve
“A chef flips a pan of prawns over a gas flame; the fire climbs, folds back and dies as steam curls into the extractor hood. Close, handheld, tungsten kitchen light.”
3s · 5.04 credits (~$2.02)
Generate on Kling V3 Pro →Proof
Same prompt, this engine.
One prompt was sent to eight engines from the same starting frame. This is what Kling V3 Pro did with it. The prompt, word for word: “A paper boat the size of a ship sails through a flooded cathedral at dawn, candle flames guttering as it passes, water lapping the stone, slow lateral dolly, 35mm, natural light, the sound of water and wind, continuous motion, no cuts, no new objects”
Kling V3 Pro, run on the prompt above at 1080p · 8s · 13.44 credits (~$5.38). Tap or scroll and the still becomes the clip.

Kling V3 Pro, answered.
How can I use Kling AI outside China?
King AI carries Kling V3 Pro, V3 Standard, V3 Turbo Pro, V3 4K, O3 Pro, O3 Standard and O3 4K globally on iPhone, iPad, Mac and the web. There is no separate Kling account, no regional sign-up and no second subscription — generations come out of the same credit balance as every other model.
What clip lengths does Kling V3 Pro support?
Any whole number of seconds from 3 to 15. That is the widest range of any video family in King AI, and because billing is per second you pay for the exact length rather than rounding up to a fixed tier.
How much does a Kling V3 Pro video cost in King AI?
Kling V3 Pro costs 1.68 credits per second, so a clip of 5 seconds costs 8.4 credits and one of 15 seconds costs 25.2. Kling V3 Standard costs 1.26 credits per second. Both output 1080p with audio. In most countries, your first video is on us: new verified accounts get one five-second video on our lowest-cost video model, once. A three-second Kling V3 Pro run costs more than the first video on us, so it needs credits from a plan or credit pack.
Can Kling generate 4K video?
Yes. Kling V3 4K and Kling O3 4K generate at 4K from a prompt or a still, any length from 3 to 15 seconds with audio, at 4.2 credits a second. Kling O3 4K Reference V2V restyles a clip you already have at 4K. To keep the cost down, draft at 1080p and re-run the keeper at 4K.
Is Kling better than Veo 3.1?
For length and cost, yes — Kling reaches 15 seconds and bills 1.68 credits a second against Veo's 4. For dialogue, Veo leads. Both have a native 4K tier; Kling's bills 4.2 credits a second against Veo 3.1 4K's 6. The two are a natural pair: draft the movement on Kling, deliver the hero shot on Veo.
