How to Use Kling 3.0 Omni Image-to-Video: 4K, Native Audio, Real Credit Costs
A practical guide to Kling 3.0 Omni Image-to-Video on VdoBloom: 3-15 second clips at 720p, 1080p or 4K with native audio, the exact credit table, and how to prompt it.
Kling 3.0 Omni Image-to-Video on VdoBloom animates an uploaded photo into a 3 to 15 second clip at 720p, 1080p or 4K with native audio always generated alongside the picture, starting at 24 credits for a 3-second 720p clip and running to 402 credits for 15 seconds at 4K. It is the most capable image animator in the Kling family on the platform, and the pricing is per-duration rather than flat, so choosing the right length and resolution is most of the cost control. Here is how to run it properly.
What the model is actually for
Kling 3.0 Omni Image-to-Video is a single-shot animator: one uploaded image in, one continuous shot out. It does not storyboard multiple cuts, and it does not do text-to-video — the text-to-video sibling is a separate model in the same family. What distinguishes the Omni variant from the rest of the Kling lineup is that audio is generated natively with the video rather than added afterwards, and that it reaches a genuine 4K tier.
That combination makes it the right pick for hero shots: the one clip in a piece of content that has to look and sound finished on its own. A 5-second product reveal with the right room tone, a character portrait that comes alive with ambient sound, a landscape still that gains wind and birdsong. For filler b-roll it is overkill, and the credit table will tell you so.
Two honest limits. First, the aspect ratio is not selectable. VdoBloom hides the ratio picker for this model on purpose, because the upstream API only accepts automatic framing for single-shot image-to-video — the output follows the shape of the image you upload. Crop before you upload, not after. Second, the Kling family sits in the strict content-filter tier, so your image and your prompt are both screened before the job runs.
If your source photo shows a real, identifiable person, you must have that person’s consent before animating them. That applies to every photo-motion model on VdoBloom, and it is not optional.

Exact credit cost per tier
These are the real numbers from the credit table, converted at the Lite rate of $15 for 300 credits, so 1 credit is $0.05. Every whole second between 3 and 15 is priced; the rows below are the common ones.
| Duration | 720p | 1080p | 4K |
|---|---|---|---|
| 3 seconds | 24 credits ($1.20) | 33 credits ($1.65) | 81 credits ($4.05) |
| 5 seconds | 40 credits ($2.00) | 54 credits ($2.70) | 134 credits ($6.70) |
| 8 seconds | 64 credits ($3.20) | 87 credits ($4.35) | 215 credits ($10.75) |
| 10 seconds | 80 credits ($4.00) | 108 credits ($5.40) | 268 credits ($13.40) |
| 15 seconds | 120 credits ($6.00) | 162 credits ($8.10) | 402 credits ($20.10) |
Read the shape of that table before you spend anything. Going from 720p to 1080p costs roughly 35 percent more. Going from 1080p to 4K costs roughly two and a half times more again — a 10-second 4K clip is 268 credits, more than three 10-second 1080p clips. The practical workflow is to prototype the motion at 720p and 3 seconds for 24 credits, and only re-run the prompt that worked at the resolution and length you actually need. That discipline is the difference between a $6 hero shot and a $60 one.
Note that a new account’s 10 free credits do not cover even the cheapest tier here, so you will need a pack or a plan first. One-time credit packs start at $2.49 for 75 credits and never expire, which is enough for three 3-second 720p tests; subscriptions start at $15 a month for 300 credits. Details are on the pricing page.
How to prompt it well
The prompt has two jobs on this model that it does not have on silent animators: it steers motion, and it steers sound.
- Describe change, not content. The model already has your image. Write what happens over the next few seconds — the dress hem lifts, the neon sign flickers, the subject exhales and looks up.
- Name the soundscape explicitly. Because audio is generated alongside the frames, a prompt that ends with quiet rain on the window, distant traffic, no music gets you a far more usable track than one that says nothing and leaves the model to guess.
- One camera move. Slow dolly in, slight handheld sway, or locked off. Two or three stacked moves in a short clip is the main cause of warping around edges.
- Protect what must not deform. Adding the logo stays flat and legible, or the face keeps its proportions, does real work on product and portrait shots.
- Match prompt length to clip length. Three seconds holds one idea. Fifteen seconds can carry a beginning, a middle and a resolution — write it as a short sequence, in order.
Source images behave the same way here as on every animator: sharp, well-lit, subject fully inside the frame, no heavy motion blur, no dense on-image text. A 4K render of a soft phone snapshot is an expensive way to get a soft clip.
A worked example
Take a 9:16 portrait of a dancer standing still in a studio, shot on a decent camera. Open the image-to-video tab, upload the frame, choose the Kling family and the V3.0 Omni Image-to-Video variant, set 720p and 3 seconds, and check the cost preview reads 24 credits.
Prompt: she rolls her shoulders and steps forward into the light, hair moving naturally, camera pushes in slowly, background stays in soft focus, audio is quiet studio room tone with soft footsteps and no music.
If the motion reads correctly at 24 credits, re-run the identical prompt at 1080p and 8 seconds for 87 credits — the framing stays 9:16 because it follows the source image. Reserve 4K for the single frame that will be seen full-screen. On a paid plan the download is watermark-free with commercial rights; the watermark-free guide explains how that applies across the catalog.
When to pick a different model
- You want a flat, simple price. Kling 2.6 Image-to-Video is 22 credits for 5 seconds or 44 for 10, silent, single HD tier, nothing to configure. For batches of uniform clips it is cheaper and easier to budget.
- You do not need audio. Paying for a generated soundtrack you will mute and replace in an editor is waste. A silent per-second animator such as Kling V3 Turbo Image-to-Video covers 3 to 15 seconds at 720p or 1080p without it.
- You need a specific output ratio the source does not have. There is no ratio picker on this model. Crop first.
- Your subject sits outside strict filtering. Kling runs strict content filters. VdoBloom labels each model by filter strictness, and the more flexible tiers handle swimwear, dance, fitness and fashion work that strict models refuse. Explicit and illegal content is blocked across the whole platform.

Frequently asked questions
How much is a 5-second Kling 3.0 Omni image-to-video clip?
40 credits at 720p, 54 credits at 1080p and 134 credits at 4K — $2.00, $2.70 and $6.70 at the Lite rate of $15 for 300 credits. The cost preview shows the exact number before you generate.
Can I choose 16:9 or 9:16 output?
Not on this model. Single-shot image-to-video uses automatic framing and the clip inherits the shape of the uploaded image, so crop your source to the ratio you want before uploading.
Does it really generate audio automatically?
Yes. Audio is requested on every job and the credit table already prices the with-audio rate, so there is no cheaper silent tier to fall back to. Describe the soundscape you want in the prompt.
What durations are available?
Every whole second from 3 to 15. Each second is priced individually, so a 7-second clip costs less than an 8-second one rather than rounding up to a fixed tier.
Is 4K worth the credits?
Only for a hero shot that will be viewed large. At 268 credits for 10 seconds it costs more than three 1080p clips of the same length, and social platforms re-compress heavily. Prototype at 720p, deliver at 1080p, and spend 4K sparingly.
