We bill both of these through the same wallet, so we can do something an affiliate comparison cannot: state what each one costs per second of finished video on one account, and what each one will and will not render. Kling 3.0 Pro and Google Veo 3.1 both open at Starter and both are paid in ✦ gold, and there the resemblance ends. One of them is roughly four times the price of the other per second, and the cheaper one is also the more flexible. Here is the whole picture.
Everything below comes out of the manifests that drive the composer's own price estimate, the validation on the submit and the charge at completion. There is one formula and three places read it, which is why the number on the Generate button is the number that gets deducted.

Two entries in that table are worth pausing on. Kling has one resolution, and that is not a limitation we imposed — the request carries no resolution field at all, so the provider renders its native tier whatever a menu might have shown. A picker offering 480p through 4K on this model would have been decorative: same clip, same price, at every supposed tier. Veo has two resolutions that cost the same, because its price here carries no resolution multiplier. If you are running Veo, ask for 1080p. There is nothing to save by not.
The length menus diverge in a way that shows up in a working day rather than in a spec sheet. Kling offers thirteen lengths starting at three seconds, so a draft costs ✦12 and you can be wrong four or five times for less than one finished Veo shot. Veo offers three lengths, the shortest of them four seconds, and its cheapest possible press is ✦67 — more than five times Kling's. Iteration cost is not a footnote on a video model. It is most of what you will actually spend.
| Clip length | Kling, silent | Kling with sound | Veo, silent | Veo with sound |
|---|---|---|---|---|
| 4 seconds | ✦16 | ✦23 | ✦67 | ✦134 |
| 6 seconds | ✦23 | ✦35 | ✦101 | ✦201 |
| 8 seconds | ✦31 | ✦46 | ✦134 | ✦268 |
| 15 seconds | ✦57 | ✦86 | Not offered | Not offered |
The multiple grows when you switch sound on, because the two providers surcharge it differently: Kling bills 1.5 times for a clip with audio, Veo bills double. So at 8 seconds silent, Veo is 4.3 times Kling. At 8 seconds with sound, Veo is 5.8 times Kling — ✦268 against ✦46 for the same length of footage.
What it costs: Set against the plan grants, one 8-second Veo clip with sound at ✦268 is more than five months of a Starter plan's ✦50 gold grant, and more than two thirds of a Creator month's ✦380. The same eight seconds on Kling with sound is ✦46 — a Creator plan's grant is roughly eight of them. Whatever you believe about the two models' output, that is the constraint you will actually run into.
Veo has three mutually exclusive input lanes: a plain prompt; a first frame with an optional last frame; and a set of up to three ingredient images that hold a subject, a product or a palette steady without pinning the framing. The third lane is fixed at 8 seconds. Pick 4 seconds with ingredients attached and 8 seconds is what renders and what gets billed.
Watch out: The composer quotes at the value that will actually run rather than the value you clicked, and flags the difference on the card. That is the promise it has to keep — never charge above the shown price — but it does mean a 4-second Veo reference run is a ✦134 press, not a ✦67 one.
Kling's image lane has its own quiet behaviour worth knowing: attach a frame and the aspect-ratio picker disappears, because the attached image decides the geometry. The end frame is offered only once a start frame exists, which is the only order in which a guided transition means anything.
We have not run a blind quality study on these two models and we are not going to publish scores we did not produce. What we will say is what these lanes are reached for here. Kling is the family people use for human motion — weight, balance and follow-through in a body, which is the failure mode most video models still have — and it brings two neighbours with it: Motion Control, where a still character performs a reference clip, and O1, which edits footage you already have from a written instruction. Veo generates its sound in the same pass as the picture rather than having a track laid over afterwards, and its ingredient lane is the cleanest way here to hold a look across several separate clips.
Neither of those is a scoreboard. Both are checkable in an afternoon on your own footage, which is a better use of an afternoon than reading somebody's ranked list.
Open the video composer — Tick both models to run one prompt through each. Nothing runs until you press Generate.
One habit worth forming with either model: settle the prompt and the framing at the shortest length the model offers, and only then buy the length you need. Both bill strictly by the second with no flat component, so a fifteen-second Kling clip costs about five times a three-second one and there is no discount for committing early. The Generate button carries the total before you press it, and a model whose inputs cannot be met is skipped by name with the reason rather than quietly dropped — but neither of those makes a wrong fifteen-second render cheaper than a wrong three-second one.
Kling, by a long way. ✦3.8 a second against ✦16.7, both at 1080p. With native sound switched on the gap widens further, because Kling surcharges audio at 1.5 times and Veo at double: an 8-second clip with sound is ✦46 on Kling and ✦268 on Veo.
Kling 3.0 Pro renders every whole second from 3 to 15. Veo 3.1 renders 4, 6 or 8 seconds and nothing in between — and its ingredient-image lane is pinned to 8.
1080p. Veo's price here carries no resolution multiplier, so the two tiers cost the same and 720p buys you nothing.
Not on these two — both are hosted models that bill per call and need ✦ gold from the Starter plan up. The free video lane is the models running on our own GPUs, LTX 2.3 and MiniMax H3 Studio, paid from the green wallet and clamped to a 480 px short side on a free account.
Yes. Both models publish a sound option and both surcharge it — Kling at 1.5 times the silent price, Veo at double. The toggle is in the composer and the quote moves with it before you press.
Yes. The video model picker takes several models at once and one press fans the prompt out; each card carries its own quote, and any model whose inputs cannot be met is skipped with the reason named rather than silently dropped.
