Kling 3.0 在 Omnely 的每秒點數收費拆解

AI video pricing is usually quoted in plans and monthly buckets, which makes it hard to answer a simple question: what does one clip cost? We build Omnely, a multi-model AI workspace, and we offer Kling 3.0 there, so we had to work this out per second. Disclosure: this is our own product, and everything below is about how Kling 3.0 is billed on Omnely, not on Kling's own site.

The unit: credits, and what they're worth

On Omnely, 1 credit equals $0.01. Kling 3.0 is billed per second of output, and the rate depends on only two toggles: mode (std or pro) and whether sound is on.

Clips run from 3 to 15 seconds. That puts the floor at 36 credits ($0.36) for a 3-second silent std clip. The ceiling is 360 credits ($3.60) for 15 seconds of pro with sound. Sound is on by default, so the default 5-second std clip is 90 credits ($0.90).

Totals for common lengths

The formula is seconds × rate. Here are a few totals:

Aspect ratio (16:9, 9:16 or 1:1) and prompt length (up to 2,500 characters) don't change the price. Neither do reference images. Kling 3.0 accepts up to two, and there is no per-image surcharge.

A worked example: draft cheap, finish once

Say you want a single 8-second hero shot for a social post, with sound. The tempting approach is to iterate at the final settings. Eight-second pro with sound costs 8 × 24 = 192 credits ($1.92) per attempt. Six attempts would be 1,152 credits, or $11.52.

Here's a cheaper workflow that uses only the rates above:

1. Draft the idea in 3-second std silent clips: 36 credits ($0.36) each. Run six of them to settle composition and prompt wording: 216 credits ($2.16).
2. When one works, render the final once at 8 seconds, pro with sound: 192 credits ($1.92).

Total: 408 credits, or $4.08. That's roughly a third of the cost of iterating at full settings. The caveat is that a 3-second std silent draft won't show you everything. Pro mode may change motion and faces, so you might still spend one extra pro attempt. Even so, you'd still come out well ahead.

Four ways to cut the bill

1. Duration is the biggest lever. Each extra second adds exactly one per-second rate. Going from 5 to 10 seconds doubles the cost. Trim your shot list to the seconds you'll actually keep.

2. Switch sound off if you'll replace it. Sound adds 6 credits per second in std and 7 in pro. If a voiceover or licensed track is going on top anyway, a 5-second std clip drops from 90 to 60 credits, and a 5-second pro clip from 120 to 85.

3. Treat pro as a finishing mode. By our arithmetic from the table, pro costs about 42% more than std when silent (17 vs 12) and about 33% more with sound (24 vs 18). Use std for loops, mood cuts and iteration, and pro when a shot needs tighter motion or cleaner faces.

4. Read the total before you generate. The credit total is shown on the model page before you run anything. If you nudged the duration slider from 5 to 7 seconds without noticing, the number on the page is the one you'll be charged.

Things to know before you try it

• Credits are one wallet across chat, image, video and audio on Omnely, so unused video credits aren't stranded. Purchased top-up credits don't expire.
• New users get free credits on sign-up, but video models require a paid Omnely plan afterwards. We haven't covered plan prices here.
• Omnely isn't Kling and doesn't resell Kling's own memberships. Kling 4.0 is not available on Omnely; only Kling 3.0 is. If you need 4.0-only features, you'd use Kling's own membership.

If you want the full ladder with more worked totals (3, 5, 8 and 10 seconds, plus a six-clip example), we wrote it up in our Kling 3.0 price-in-credits breakdown. You can check live numbers by adjusting mode, duration and sound on the Kling 3.0 model page.

Rates can change over time. Treat the page total as the source of truth rather than any number in this article, including ours.
