Kling 2.6 Image-to-Video vs Kling 3.0 Omni Image-to-Video: Credits, Length and Audio Compared
Kling 2.6 Image-to-Video is 22 or 44 credits for a fixed 5 or 10 seconds; Kling 3.0 Omni Image-to-Video runs 3-15s at 720p, 1080p or 4K with native audio from 24 credits. Exact costs and when each wins.
Kling 2.6 Image-to-Video is the cheap, fixed-length option — 5 or 10 seconds, one quality tier, 22 or 44 credits — while Kling 3.0 Omni Image-to-Video is the flagship: any length from 3 to 15 seconds, 720p, 1080p or 4K, native audio baked in, from 24 credits. On VdoBloom both models animate a still photo from the same Image to Video tab, so the only real decision is how much length, resolution and sound your shot needs, and how many credits you want to spend finding out.
The short version
Kling 2.6 Image-to-Video shipped in December 2025 and still earns its place as the draft model. It takes your photo plus a prompt and gives you a clean HD clip. There is no resolution picker, no aspect-ratio picker and no duration slider beyond two stops, which sounds limiting until you realise that is exactly why it is fast to reason about and cheap to iterate on.
Kling 3.0 Omni Image-to-Video arrived in August 2026 and is a different class of model. It generates native audio with the video rather than leaving you a silent clip, it will run to fifteen seconds in a single shot, and it offers a genuine 4K tier. It also costs up to six times more per second at the top tier, so it is a finishing model, not a drafting one.
Spec for spec

|---|---|---|
| Durations | 5s or 10s only | Every second from 3s to 15s |
| Resolutions | Single HD tier (no picker) | 720p, 1080p, 4K |
| Aspect ratio | Follows the input image | Follows the input image |
| Native audio | No | Yes, always on |
| Input | One photo plus a prompt | One photo plus a prompt |
| Content filter | Strict (Kling family) | Strict (Kling family) |

| Longest clip | 44 credits (10s) | 402 credits (15s at 4K) |
What each clip actually costs
VdoBloom prices everything in one credit pool. On the Lite plan, $15 buys 300 credits, so one credit is $0.05. Here is what the two models bill for the lengths people actually pick.
| Model and tier | Length | Credits | Dollar cost |
|---|---|---|---|
| Kling 2.6 Image-to-Video | 5s | 22 | $1.10 |
| Kling 2.6 Image-to-Video | 10s | 44 | $2.20 |
| Kling 3.0 Omni — 720p | 3s | 24 | $1.20 |
| Kling 3.0 Omni — 720p | 5s | 40 | $2.00 |
| Kling 3.0 Omni — 720p | 10s | 80 | $4.00 |
| Kling 3.0 Omni — 1080p | 5s | 54 | $2.70 |
| Kling 3.0 Omni — 1080p | 10s | 108 | $5.40 |
| Kling 3.0 Omni — 4K | 5s | 134 | $6.70 |
| Kling 3.0 Omni — 4K | 10s | 268 | $13.40 |
| Kling 3.0 Omni — 4K | 15s | 402 | $20.10 |
Read those numbers as rates and the picture gets clearer. Kling 2.6 bills a flat 4.4 credits per second at either length. Kling 3.0 Omni bills 8 credits per second at 720p, 10.8 at 1080p and 26.8 at 4K. So a 720p Omni clip is roughly 1.8 times the price of the same length on 2.6, and a 4K Omni clip is about six times. Omni charges by the second rather than by the stop, which means a 7-second clip costs exactly seven seconds of credits instead of being rounded up to ten.
When Kling 2.6 is the right call
Pick 2.6 when you are testing framing, motion direction or a prompt phrasing and you expect to run the same photo five or six times before you like one. Six 5-second drafts on 2.6 cost 132 credits. The same six drafts at 1080p on Omni cost 324. Draft cheap, finish expensive.
It is also the right pick for silent social cutdowns where you will lay your own music or voiceover over the top anyway. Omni’s native audio is a real feature, but it is not free, and you are paying for it on every generation whether you keep the track or mute it.
When Kling 3.0 Omni earns its price
Three cases justify the jump. First, anything longer than ten seconds — 2.6 simply cannot do it, and stitching two 2.6 clips rarely matches on lighting and motion. Second, anything where ambient sound is the point: a product hitting a counter, footsteps on gravel, a room tone that sells the shot. Third, delivery at 4K, which matters for paid placements and large-screen work and has no equivalent on 2.6.
A worked example. You have a product photo and want a hero clip for a landing page: 8 seconds, 1080p, with the sound of the bottle being set down. On Omni that is 87 credits, or $4.35. Getting there on 2.6 would mean a 10-second silent clip at 44 credits, a separate sound design pass, and no 1080p guarantee. The 43-credit gap buys away an entire editing step.
What neither model will do
Both sit in the Kling family, which is labelled strict on VdoBloom’s content-filter scale. Swimwear, dance, fitness and fashion work that mainstream tools refuse is better routed to a flexible-tier model — Wan 2.7 Image-to-Video is the usual substitute, and it will accept briefs the Kling models bounce. Explicit and illegal content stays blocked everywhere on the platform, on every model and every tier.
Neither model invents a camera angle your photo does not contain. Both follow the aspect ratio of the image you upload, so crop before you generate, not after. And if the photo shows a real person, you must have that person’s consent before animating them — that is a rule, not a suggestion.
How to run the comparison yourself
Open the Image to Video tab, upload one photo, and generate the same prompt on both models at 5 seconds. That costs 22 credits on 2.6 and 40 on Omni at 720p — 62 credits total, well inside what a single credit pack covers. New accounts get 10 free credits with no card, which is enough to sanity-check the workflow before you commit. Full specs live on the Kling 2.6 Image-to-Video page and the Kling 3.0 Omni Image-to-Video page, and the credit maths for every plan is on pricing.
Frequently asked questions
Is Kling 3.0 Omni always better than Kling 2.6?
No. It is better when you need length past ten seconds, native audio or 4K. For silent 5-second drafts it is nearly twice the price for an output you may discard.
Can I choose the aspect ratio on either model?
Not directly. Both take the aspect ratio from your uploaded image, so crop the photo to 9:16 or 16:9 before uploading.
Can I turn off audio on Kling 3.0 Omni to save credits?
No. Native audio is always on for Omni and is included in the per-second rate. If you never want the audio, Kling 2.6 is the cheaper path.
Do my credits expire?
Credits from one-time packs never expire. Packs start at $2.49 for 75 credits, which covers three 5-second Kling 2.6 clips.
