Kling 3.0 Omni text-to-video on VdoBloom costs a flat 8 credits per second at 720p, 10.8 credits per second at 1080p and 26.8 credits per second at 4K, with native audio always included in that price. In practice that means a 5-second 720p clip is 40 credits, the same clip at 1080p is 54 credits, and at 4K it is 134 credits. There is no separate audio charge and no per-render surcharge — the only two numbers that move the bill are the resolution you pick and the number of seconds you ask for, anywhere from 3 to 15.

How credits turn into dollars

VdoBloom prices everything in one credit balance. The simplest anchor is the Lite subscription: $15 a month for 300 credits, which makes one credit exactly $0.05. Every dollar figure in the table below uses that rate, because it is the most expensive credit you can realistically buy on a paid plan. Buy deeper and the per-credit price falls — the Pro 2,000-credit tier on annual billing is $49 a month, which works out to about $0.0245 per credit, roughly half the Lite rate. So treat the dollar column as a ceiling, not a fixed price.

New accounts start with 10 free credits and no card. Be aware of what that does and does not buy here: the cheapest possible Kling 3.0 Omni render is a 3-second 720p clip at 24 credits, so the free balance does not cover a single Omni generation. If you want to spend the free credits on video before committing, start with a cheaper family and come back to Omni once you have topped up. Full plan and pack numbers are on the pricing page.

Kling 3.0 Omni text-to-video: every tier, exactly

These are the real numbers from the credit table, not estimates. Durations are whole seconds from 3 to 15; the table shows the common ones.

Duration	720p credits	720p at $0.05/cr	1080p credits	1080p at $0.05/cr	4K credits	4K at $0.05/cr
3s	24	$1.20	33	$1.65	81	$4.05
4s	32	$1.60	44	$2.20	108	$5.40
5s	40	$2.00	54	$2.70	134	$6.70
6s	48	$2.40	65	$3.25	161	$8.05
8s	64	$3.20	87	$4.35	215	$10.75
10s	80	$4.00	108	$5.40	268	$13.40
12s	96	$4.80	130	$6.50	322	$16.10
15s	120	$6.00	162	$8.10	402	$20.10

Two things fall out of that table immediately. First, the pricing is genuinely linear inside each resolution, so a 15-second clip costs exactly five times a 3-second clip — there is no volume discount for asking for a longer single shot, and no penalty either. Second, 4K is not a modest step up. It is about 3.35 times the 720p rate and about 2.5 times the 1080p rate. A 15-second 4K render at 402 credits costs more than an entire Lite month.

Why the price includes audio whether you want it or not

Kling 3.0 Omni generates native audio in the same pass — ambience, effects and dialogue with matching lip movement — and there is no toggle to switch it off for a discount. That is the single most important fact about its pricing. If your clip is going into an edit where you will lay your own music and sound design over the top, you are paying for audio you will mute.

The comparison that matters is with the flagship Kling 3.0 model, which runs the same 3–15 second range but exposes sound as an option. With sound switched on, Kling 3.0 standard mode bills 8 credits per second and pro mode bills 10.8 — identical to Omni at 720p and 1080p. With sound switched off, the same model drops to 5.6 and 7.2 credits per second. That is a 30 to 33 percent saving on every silent clip.

Model and setting	Credits per second	5s clip	Audio
Kling 3.0 (std, silent)	5.6	28 cr	No
Kling 3.0 (pro, silent)	7.2	36 cr	No
Kling 3.0 Omni 720p	8.0	40 cr	Always on
Kling 3.0 Omni 1080p	10.8	54 cr	Always on
Kling 3.0 Omni 4K	26.8	134 cr	Always on

So the honest rule is: pick Omni when the sound is part of the deliverable, and pick silent Kling 3.0 when it is not.

Choosing a resolution without wasting credits

720p at 8 credits per second is the right default for drafting. Prompts for video are unpredictable enough that the first render is usually a test of whether the idea works at all, and a failed idea at 720p costs 40 credits instead of 134. Once the composition, camera move and dialogue are landing, re-run the same prompt at a higher resolution.

1080p at 10.8 credits per second is the delivery tier for almost everything that ends up on social, in an ad, or on a website. It is a 35 percent premium over 720p, which is small enough that you should not agonise over it for a final render.

4K at 26.8 credits per second is for work that will be projected, cropped heavily in post, or intercut with real 4K footage. Paying 268 credits for a 10-second clip that will be viewed on a phone at 1080p is money thrown away. Note that Omni text-to-video also lets you set the aspect ratio directly — 16:9, 9:16 or 1:1 — so you do not need to render wide and crop, which is one of the commoner ways people waste resolution.

A worked budget

Say you are building a 30-second product spot from six shots, each 5 seconds, and you want spoken voiceover generated in the clips rather than recorded separately. Drafting all six at 720p costs 6 × 40 = 240 credits. Expect to re-roll roughly a third of them once, which is another 80 credits, bringing drafting to about 320. Final renders of the six keepers at 1080p are 6 × 54 = 324 credits. Total: about 644 credits, or roughly $32 at the Lite rate and closer to $16 if you are on an annual Pro plan. That is the realistic shape of an Omni project — the drafting passes usually cost about as much as the finals.

One relief valve worth knowing: a generation that fails outright returns its credits to your balance automatically. You are charged for renders that complete, including ones you dislike, but not for infrastructure failures.

When a different model is the cheaper answer

If you are animating a photograph rather than writing a scene, Kling 3.0 Omni image-to-video uses exactly the same credit table, so nothing changes financially — but if you only need motion and no sound, Kling 2.6 image-to-video is a flat 22 credits for 5 seconds, close to half the Omni price. If you want a fast, silent text-to-video draft, Kling V3 Turbo is 7.2 credits per second at 720p. And if what you actually want is the rest of the Kling family plus a hundred other models on one balance, the VdoBloom versus Kling AI page lays out the difference between subscribing to Kling directly and running it here.

Any Kling 3.0 Omni clip built from a photo of a real person requires that person’s consent — and because Omni also generates a voice, that consent should cover the audio as well as the likeness.

Frequently asked questions

What is the cheapest Kling 3.0 Omni text-to-video clip?

Three seconds at 720p for 24 credits, about $1.20 at the Lite rate. There is no shorter duration and no cheaper resolution.

Does 4K really cost more than three times 720p?

Yes. 720p bills 8 credits per second and 4K bills 26.8, so a 10-second clip is 80 credits versus 268. Use 4K only when the delivery format genuinely needs it.

Can I turn the audio off to save credits?

Not on Omni — native audio is part of the model and part of the price. Use Kling 3.0 with sound switched off instead, which bills 5.6 credits per second in standard mode.

Do my credits expire?

Credits bought as one-time packs never expire. Subscription credits refresh on your billing cycle. Paid plans also download without a watermark and carry commercial rights.

Is image-to-video priced differently?

No. Kling 3.0 Omni text-to-video and image-to-video share one credit table, so a 5-second 1080p clip is 54 credits either way.
