How the arithmetic works
3 of the 3 carry enough in their price matrix to work the shape through end to end, and the table below does exactly that with each model's own figures. No two billing shapes on this site share a model — a model has exactly one — so nothing here overlaps another billing page.
credits = the block figure x the number of 5-second blocks your clip occupies, rounded up. A 9-second clip pays for two blocks, which means the seconds you do not use still cost you the same as the ones you do.
| Model | One block (up to 5s) | Two blocks (up to 10s) | What a 6-second clip costs |
|---|---|---|---|
| Kling Lipsync | 7 credits | 14 credits | 14 credits — a 10-second clip costs the same |
| Luma Ray 2 720p | 50 credits | 100 credits | 100 credits — a 10-second clip costs the same |
| Seedance 1 Pro Fast | 62 credits | 124 credits | 124 credits — a 10-second clip costs the same |
Worked from each model's own price matrix. A cell reading “—” is one where the arithmetic produces a figure outside the complete-job range the same matrix declares, so nothing is printed.
All 3 models
Cheapest complete job first. Every row links to that model's spec page — tier and mode variants share a page with the model they are a variant of, so this is products rather than SKUs.
| Model | Provider | Credits per job | Its priced options |
|---|---|---|---|
| Kling Lipsync | Kling | 7-14 credits | Price 7 |
| Luma Ray 2 720p | Luma | 50-100 credits | Price 50 |
| Seedance 1 Pro Fast | ByteDance | 62-124 credits | Price 62 |
How these models are billed

All figures are Versely credits. A credit figure marked as a headline rate is not the cost of a complete job. Your plan's credit allowance is on the pricing page.

Frequently asked questions
Which AI models are billed per 5-second block?+
3 on Versely — 2 video and 1 lipsync & avatars, from 3 providers. credits = the block figure x the number of 5-second blocks your clip occupies, rounded up. A 9-second clip pays for two blocks, which means the seconds you do not use still cost you the same as the ones you do.
Is a per 5-second block model cheaper?+
Not in itself — the shape is how you are charged, not how much. Across these 3 models a complete job runs 7 to 62 credits. What the shape does tell you is which lever moves your bill, and on this page that lever is the same for every model listed.
What is the cheapest model billed per 5-second block?+
Kling Lipsync has the lowest complete-job cost of the 3 at 7-14 credits. The worked example table above shows the same arithmetic applied to every model that publishes enough of its matrix to support it.
Can I compare a per 5-second block model against one billed another way?+
Only on the cost of a complete job, never on the headline figure. That is the whole reason these pages are split by shape — a rate compared against a job total is two different quantities in one column. Versely's ranked buyer guides sort on complete-job cost for exactly this reason.
