Veo vs Kling for generated video

Kling publishes a dollar rate after all

Every CartSignal page about Kling since 31 August has carried the same caveat: its credit rates are first-party but its dollar prices are not, because the membership page renders its numbers client-side and returns nothing readable. Fetched again today, it still does.

The way around it was on a different Kling page the whole time. Kling's credits policy prices top-up credits directly: "$1 USD = 66 Credits". That is a Kling-published exchange rate, which makes a credit worth $0.015152 and turns the whole VIDEO 3.0 rate card into dollars without a tracker anywhere in the chain.

It also settles an open question. The plan price this site has carried as third-party reported — Standard renewing at about $10 a month for 660 credits — works out to $0.015152 a credit, matching the published top-up rate exactly rather than approximately. Two independent numbers landing on the same six decimal places is reasonable evidence the reported figure is right, and it means Kling's entry subscription gives you no discount at all against simply buying credits.

Two caveats stay attached. This is the top-up rate, so it is the price of a credit bought outright; higher subscription tiers are reported to buy credits more cheaply, and the 4K row comes from Kling's separate credit cost guide rather than the model user guide, which stops at 1080p.

The same second, matched on resolution and audio

Google's Gemini API pricing page sells Veo in three variants and states that all three include audio by default. Setting those against Kling with audio switched on, at the same resolution, is as close to like-for-like as generated video gets.

The columns are in price order, and Kling occupies the same column at every row. That is the finding: Kling is priced as Google's middle tier. At all three resolutions it sits above Veo 3.1 Fast and below Veo 3.1 Standard — 36% above Fast at 720p, 51% above at 1080p and 51% above at 4K, while running 66%, 55% and 24% below Standard. There is no resolution at which Kling is the cheapest second available and none at which it is the most expensive.

The two cards are also shaped differently. Google's spans 12x, from $0.05 to $0.60; Kling's audio-on rates span 3.3x, from $0.1364 to $0.4545. Kling has no cheap tier and no premium tier, just one model at one rate card, which is the same structural point this site found in avatar video, where Synthesia's flat per-minute rate gave it neither a bargain nor a surprise against HeyGen's 12x spread.

Per finished minute, audio on, the whole field orders like this: Veo Lite 720p $3.00, Veo Lite 1080p $4.80, Veo Fast 720p $6.00, Veo Fast 1080p $7.20, Kling 720p $8.18, Kling 1080p $10.91, Veo Fast 4K $18.00, Veo Standard 720p and 1080p $24.00, Kling 4K $27.27, Veo Standard 4K $36.00. For context on where that whole band sits against avatar and editing tools, the cost per finished minute ranking covers all three lanes.

Correction: Google sells 4K at two prices, not one

Corrected 17 September 2026. The Kling profile and the Veo profile both published a section yesterday concluding that native 4K is the one rung where Kling undercuts Google. That was measured against Veo 3.1 Standard at $0.60 a second, described accurately as the most expensive second Google sells — but Google sells 4K on Veo 3.1 Fast at $0.30 as well, a row that sits on the same rate card and, as it happens, in the Veo profile's own table three rows above the claim. Standard costs exactly twice Fast for the same 4K.

So the corrected statement is narrower and more useful: Kling undercuts Google at 4K only on its top plan, reported at around $180 a month, and only if you spend the whole monthly allowance before it expires. On every other route into Kling, including buying credits outright, Google's own Fast tier is the cheaper 4K second. Both pages have been updated.

One thing does survive the correction, and it is worth keeping: Kling's 4K rate is not printed on the model user guide's pricing table at all, and which plans may generate 4K is not clearly published anywhere. Google's position is explicit by comparison — its Flow credits help page lists 4K upscaling at 50 credits for Ultra subscribers only, and 1080p upscaling at 0 credits for Plus, Pro and Ultra. Both vendors gate 4K to the top of the range. Only one of them says so on a page you can read.

Audio is free on one card and half again on the other

Google's pricing page repeats the same phrase against all three Veo variants: audio is included by default. There is no silent discount and no audio surcharge, so the decision costs nothing either way.

Kling charges for it, at a flat +50% — 6 credits a second becomes 9 at 720p, and 8 becomes 12 at 1080p. The optional voice tone control adds 2 credits a second on top, so a 1080p second with audio and voice control is 14 credits against 8 silent, 75% more. Kling's own worked examples spell this out: a 5-second 1080p clip is 60 credits with native audio, 70 with voice tone control, and a 5-second 720p silent clip is 30.

That surcharge is the one place the comparison turns in Kling's favour. If you are cutting the generated audio anyway — because you are dropping in a scripted voiceover from the voice tools or a licensed music bed — Kling's silent 720p second at $0.0909 is the cheaper buy against Veo 3.1 Fast at $0.10, since Veo bills you for audio you are about to throw away. Against Veo 3.1 Lite at $0.05 it is still nearly double.

Resolution is priced inconsistently on the Google side and consistently on the Kling side, which is the reverse of what this site usually finds. Kling charges a flat +33.3% to go from 720p to 1080p at either audio setting. Veo charges +60% on Lite, +20% on Fast and +0% on Standard, where 720p and 1080p are both $0.40 — so on Veo 3.1 Standard, generating at 720p is simply worse value than 1080p for the identical money.

What one generation can produce

This is the axis where Kling wins outright, and both sides of it are first-party. Kling's model user guide describes VIDEO 3.0 as having "flexible duration ranging from 3 to 15 seconds". Google Flow bills Veo 3.1 Lite and Fast per generation of "4s, 6s, 8s videos" and Quality per "8s videos", so 8 seconds is the ceiling on a single Flow generation against Kling's 15, about 1.9 times.

That matters more than the rate for anything with a continuous action in it. A 12-second product shot is one Kling generation and two Veo generations stitched, and neither vendor promises the second clip will match the first. It also sets the largest single bill each tool can hand you: 15 seconds of Kling 4K is 450 credits, about $6.82 at the published top-up rate, while 8 seconds of Veo 3.1 Standard at 4K on the API is $4.80. Both are small enough that the constraint on either tool is the monthly allowance, not any one render — which on Kling is severe, since Standard's 660 credits buy only about 110 seconds of 720p silent video a month.

The free daily allowance, compared

These are the only two tools in this directory that hand out video credits every day, and the gap between them is wide.

Google's Flow credits page states plainly that "with or without a subscription, you receive 50 Google Flow credits per day", and prices Veo 3.1 Lite at 10 credits per generation of a 4, 6 or 8 second video. That is five generations a day, or up to 40 seconds of video with audio, at no cost and with no card. Veo 3.1 Quality is out of reach on that allowance at 100 credits a generation, because the daily credits do not roll over.

Kling is reported to give 66 credits a day, which at 9 credits a second is about 7 seconds of 720p with audio, or 11 seconds silent — roughly a fifth of Google's, on the audio-on comparison. And there is a wrinkle worth flagging: Kling's own credits policy describes daily credits as something "Kling subscribers can claim" upon login, not something every logged-in user receives. The widely reported 66-a-day free tier may well be accurate, but CartSignal could not confirm it for a non-subscriber on a Kling page, so it is published here as reported.

Free output is reported to be watermarked on both, and neither vendor makes that easy to pin down. Kling free output is reported capped at 360p to 540p with a visible logo. Google's visible watermark is reported to be removed only at the Ultra tier, though a Google support community thread from Ultra subscribers disputes even that, and CartSignal could not find a Flow help page that states the policy. If an unwatermarked file matters, test before you commit — and note that the commercial use rights question is separate from the watermark question on both tools.

Google's other door bills per generation, not per second

Everything above uses the Gemini API, because it is the surface where Google and Kling quote the same unit. Google's other surface does not. On Flow, Veo is billed per generation — 10 credits for Veo 3.1 Lite and 20 for Fast, for a 4, 6 or 8 second video.

Duration is therefore free on Flow and linear everywhere else. A 4-second Fast clip and an 8-second Fast clip both cost 20 credits, so the short one costs exactly twice as much per second. The practical rule is that on Flow you should always generate at the maximum length and trim afterwards, and on the Gemini API or on Kling that advice is worthless because you pay for what you ask for.

It also produces an inversion this site has not seen from any other vendor. At Google AI Pro, reported at $19.99 a month for 1,000 Flow credits, a credit is about $0.02, so 8 seconds of Veo 3.1 Fast costs $0.40 — $0.05 a second, exactly half the $0.10 the Gemini API charges for the same model. Lite works out at half its API rate too, and Quality at about 37.5% below Veo 3.1 Standard. Everywhere else in this directory the developer API undercuts the studio subscription, sometimes by 10x, as on Speechify and ElevenLabs. Here the subscription appears to undercut the API.

Two conditions have to hold for that to be real, and both are unverified. Google's credit table does not state a resolution for any Veo row, so the Flow clip may not be the 720p clip the API rate buys — reporting suggests free and lower tiers are capped at 720p. And the plan dollar prices are not readable on Google's own plan pages, which rendered credit allowances but no US prices when fetched today. Treat it as a reason to price Flow before defaulting to the API, not as a settled rate.

What this comparison does not tell you

Price is the only thing measured here. Two models at the same rate can be nothing like each other on screen, and prompt adherence, motion coherence, hands and faces are exactly the things a rate card cannot show. Independent leaderboards rank these models against each other on output, and that ranking is a separate question from this one.

Nor is this a comparison of everything either company sells. Kling runs a back catalogue of older models at lower rates and a separate API resold through third parties; Google runs Gemini Omni Flash alongside Veo at roughly $0.10 a second. Both are covered on the profiles. And if what you actually need is a person talking to camera rather than a generated scene, neither of these is the category — HeyGen and Synthesia are, and the avatar roundup compares them.

FAQ

Is Veo or Kling cheaper per second?

Veo, at every resolution, unless you are on Kling's top plan. Matched on audio and resolution, Kling sits above Veo 3.1 Fast and below Veo 3.1 Standard at 720p, 1080p and 4K, so it is never the cheapest second and never the dearest.

How much is native 4K on each?

Kling charges 30 credits a second, about $0.4545 at its published top-up rate. Google charges $0.30 on Veo 3.1 Fast and $0.60 on Veo 3.1 Standard. Only Kling's reported Ultra plan, at about $0.208, beats Google's cheaper 4K rate.

Does either charge extra for audio?

Kling adds a flat 50% for native audio and 2 more credits a second for voice tone control. Google includes audio by default on all three Veo variants at no surcharge.

Which makes the longer clip in one pass?

Kling, at 3 to 15 seconds against 8 seconds per Flow generation for Veo — about 1.9 times. Longer pieces on either tool mean stitching clips with no guaranteed continuity.

Is this comparison based on hands-on testing?

No. It is a public-data comparison. Rates are quoted from official pricing pages, model guides and help centres checked on 17 September 2026, and the dollar figures are CartSignal arithmetic on those published rates. No video was generated and no claim is made about output quality.
