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) |
| Image to video, V3 Pro | Kling V3 Pro | 1080p | 3–15s | Yes | 1.68 per second (~$0.67) |
| Text to video, V3 Standard | Kling V3 Standard | 1080p | 3–15s | Yes | 1.26 per second (~$0.50) |
| Text to video, O3 Pro | Kling O3 Pro | 1080p | 3–15s | Yes | 1.4 per second (~$0.56) |

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 and 5 for Sora 2 Pro — under half the first and about a third of the second.
Start and end frame
Give Kling an opening and a closing image and it generates the motion between them — a mode Sora does not offer at all.
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.
Generation tops out at 1080p. Kling's 4K path is a reference video-to-video pass that restyles an existing clip; it is not a way to generate a 4K shot from a prompt. For that, use Veo 3.1 4K or Seedance 2.0 4K.
Length is the price, and it undoes the saving faster than people expect: 15 seconds of Kling V3 Pro is 25.2 credits, more than 8 seconds of Veo 3.1 at 32. Kling is cheap per second, not cheap per clip.
Four Kling tiers sit in the picker — V3 Pro, V3 Standard, O3 Pro and O3 Standard — and they are easy to confuse. The specs table above is the one place they 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) |
| Sora 2 Pro | 1080p | 4s·8s·12s | Yes | 5 (~$2.00) | 4s · 20 credits (~$8.00) |

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.

Kling V3 Pro, answered.
How can I use Kling AI outside China?
King AI carries Kling V3 Pro, V3 Standard, O3 Pro and O3 Standard 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, and free daily credits let you try them.
Can Kling generate 4K video?
Not from a prompt. Kling's 4K entry in King AI is a reference video-to-video pass that restyles a clip you already have. To generate at 4K from scratch, use Veo 3.1 4K or Seedance 2.0 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 native 4K and for dialogue, Veo leads. The two are a natural pair: draft the movement on Kling, deliver the hero shot on Veo.
