AI Video Credits Explained: What Each Generation Costs
Ozilai TeamHow credits map to output on Ozilai: what 720p and 1080p clips cost, why longer renders scale, where credits come from, and how refunds work.
A credit on Ozilai is a unit of rendering, not a unit of video — and one credit is not one clip. The two things that decide what a generation costs are the frame size and the length of the clip, and everything else follows from them: a standard 720p, 12-second video costs 10 credits, while the studio default of 1080p, 12 seconds costs 30. Where the credits came from, how long they last, and what happens when a render fails are all rules layered on top of that one arithmetic.

What a Generation Costs
The standard video is 720p at 12 seconds and it costs 10 credits. That is the reference point everything else is measured against, and it is also the setting you should use while you are learning how the model responds to your inputs. The studio default — what the studio is set to when you open it — is 1080p at 12 seconds for 30 credits. Same length, three times the price, because far more pixels have to be generated and held consistent across the clip. There is a cheaper tier below the standard as well: 480p at the same length is 5 credits, half the standard price, and it is the right choice when you only care whether the action is plausible and the detail does not matter.
| Output | Length | Credits | | ---------------------- | ------ | ------- | | 480p — lighter option | 12s | 5 | | 720p — standard video | 12s | 10 | | 1080p — studio default | 12s | 30 |
That single multiplier explains most of the surprise people feel when their credit balance drops faster than expected. If you generate at the studio default without changing anything, each attempt costs what three standard attempts cost. The fix is not to ration yourself; it is to know which setting you are on and choose it deliberately.
Why frame size is the biggest lever
A 1080p frame contains more than twice the pixel count of a 720p frame, and every one of those pixels has to be generated and then kept consistent from the first frame of the clip to the last. That work is what you are paying for. It is worth it when the extra detail has somewhere to go — a large screen, or a vertical crop that will throw away part of the frame and needs the subject to survive with detail intact. On a phone at native size, a 720p clip already reads as convincingly photographic.
Longer Clips and Bigger Frames
Duration scales from the same 12-second rate. The credit cost rises with the length of the clip, and every result is rounded up to a whole credit, so a clip that lands between two whole numbers is charged at the higher one. The studio offers three durations — 4, 8, and 12 seconds — and because of the round-up, a 4-second 720p clip costs 4 credits rather than a neat third of 10. Here is every combination, priced:
| Resolution | 4s | 8s | 12s | | ---------- | --- | --- | --- | | 480p | 2 | 4 | 5 | | 720p | 4 | 7 | 10 | | 1080p | 10 | 20 | 30 |
Read across a row to price every duration at one resolution; read down a column to see what the extra detail costs at a fixed length. There are no fractional credits sitting in your balance and no way to be billed a fraction of a credit for a fraction of a second.
Aspect ratio does not change the price
This is the reassurance most people are looking for, and it is worth stating plainly: rendering the same clip as vertical 9:16 or widescreen 16:9 costs the same number of credits. The frame is the same size in pixels; only its shape changes. That means the format decision belongs to your distribution plan rather than to your budget. If the clip is going to TikTok, Reels, or Shorts, plan the vertical crop from the beginning and let the credit math stay exactly where it was going to be anyway.
| Setting | Does it change the credit cost? | | ------------------ | ------------------------------------------------------ | | Resolution | Yes — 720p is 10 credits, 1080p is 30 for the same 12s | | Duration | Yes — scales with length, rounded up to a whole credit | | Aspect ratio | No — vertical and widescreen cost the same | | Number of attempts | Yes — each generation is charged on its own |
The last row of that table is the one that actually governs your monthly spend. Credits are charged per generation, so the real budget question is not "how much is a video" but "how many attempts will it take to get the video I want". Two or three attempts is a realistic working range for a short clip: one to see what the model does with your input, one after fixing the single biggest miss, one to polish.
Where Your Credits Come From
Your balance is not one pool. Credits arrive from three different sources, and each source has its own expiry rule. The rule that ties them together is simple and it works in your favour: when you generate, the soonest-expiring credits in your balance are spent first. You never watch a monthly allowance lapse while a pile of non-expiring pack credits sits untouched beside it.
Subscription credits
A monthly plan grants its credits for the billing period. Starter gives 20 credits a month for $9.90, Basic gives 60 for $19.90, Pro gives 200 for $39.90, and Studio gives 500 for $79.90. Those credits are yours to use within the period they were granted for; they are the fastest-expiring credits in your account, so the spend-first rule means they are consumed before anything longer-lived.
Yearly credits
A yearly plan grants a much larger allowance that lasts for the billing year: $79 for 240 credits, $159 for 720, $319 for 2,400, and $639 for 6,000. The credits work identically to subscription credits except for the clock — they are good for the year rather than the month, which makes them slower to expire and therefore second in the spending order.
One-time pack credits
Credit packs are bought outright rather than granted on a schedule: $9.90 for 10 credits, $19.90 for 30, $39.90 for 100, $79.90 for 250, and $149 for 600. Pack credits never expire. They sit at the bottom of the spending order precisely because they are the ones you can afford to keep. If you want a single clip for a joke and do not want a subscription, a pack is the honest answer.
| Source | How it arrives | Expiry | Spending order | | --------------------- | --------------------------------- | ------------------------- | -------------- | | Subscription credits | Monthly grant with a monthly plan | End of the billing period | First | | Yearly credits | Annual grant with a yearly plan | End of the billing year | Second | | One-time pack credits | Bought directly, no schedule | Never expire | Last |
A new account starts at zero credits if you sign up by email and earns them through a daily check-in: the first three check-ins give 10, 20, and 30 credits, and the remaining four give 10 each. Signing in with Google instead grants a one-time 30-credit bonus. Either route is enough to run a few standard generations and find out whether the tool does what you need before committing to a plan.
Plan by Plan: What a Video Really Costs
Headline credit counts are not the useful number. The number that matters is cost per video, which is the plan price divided by how many standard 720p, 12-second generations those credits buy. At 10 credits per standard video, that arithmetic looks like this.
| Plan | Price | Credits | Standard 720p · 12s videos | Cost per standard video | | ------- | -------------- | ------- | -------------------------- | ----------------------- | | Starter | $9.90 / month | 20 | 2 | $4.95 | | Basic | $19.90 / month | 60 | 6 | $3.32 | | Pro | $39.90 / month | 200 | 20 | $2.00 | | Studio | $79.90 / month | 500 | 50 | $1.60 |
The pattern is the usual one: the cheaper the plan per credit, the more credits you have to be willing to spend. Starter is a fair price for two experimental clips a month; Studio is a fair price if you are producing daily and the per-video cost is the thing you are optimising.
The yearly plans push the same number lower, because you are paying for a longer commitment up front.
| Yearly plan | Price | Credits | Standard videos | Cost per standard video | | ----------- | ----- | ------- | --------------- | ----------------------- | | Starter | $79 | 240 | 24 | $3.29 | | Basic | $159 | 720 | 72 | $2.21 | | Pro | $319 | 2,400 | 240 | $1.33 | | Studio | $639 | 6,000 | 600 | $1.07 |
Packs, by contrast, are the most expensive per video and the most flexible — you pay a premium for the ability to walk away.
| Pack | Price | Credits | Standard videos | Cost per standard video | | ----------- | ------ | ------- | --------------- | ----------------------- | | Single | $9.90 | 10 | 1 | $9.90 | | Duo Pack | $19.90 | 30 | 3 | $6.63 | | Party Pack | $39.90 | 100 | 10 | $3.99 | | Crew Pack | $79.90 | 250 | 25 | $3.20 | | Studio Pack | $149 | 600 | 60 | $2.48 |
One warning about reading these tables: every figure assumes the standard 720p, 12-second render. If you work at the studio default of 1080p, divide the "standard videos" column by three — 30 credits per clip rather than 10 — and the cost per video triples with it. Budgeting against the 720p column while generating at 1080p is the single most common way people run out of credits mid-month.
When a Render Fails, the Credits Come Back
A failed render is refunded automatically to the credits it came from. That last phrase is doing real work. If a 30-credit studio render fails after drawing on subscription credits, 30 subscription credits return to your balance, keeping whatever time they had left rather than being replaced with a different kind of credit. You are not compensated for a failure with new credits that outlive the ones you spent; you are simply put back where you were.
The practical effect is that a failure costs you time and not money. You do not have to open a support request to be made whole, and you should not treat a failed attempt as a reason to change your plan.

Your First Purchase, Step by Step
This is the sequence that avoids over-buying, and it is the same whether you end up subscribing or buying a single pack.
- Sign up and take the free credits. Email sign-up starts you at zero and pays out through the daily check-in — 10, then 20, then 30, then 10 for each of the remaining four days. A Google sign-in instead grants a one-time 30-credit bonus. Either way, you now have enough to test the workflow without paying.
- Run one generation at the standard setting. 720p, 12 seconds, 10 credits. This is a measurement, not a masterpiece: you are finding out what the model does with your input and how far one attempt gets you.
- Count attempts, not videos. Decide how many generations you realistically need in a month. A postable clip usually takes two or three, so ten finished videos is closer to thirty generations than to ten.
- Choose the smallest thing that covers that count. Two or three generations a month fits Starter's 20 credits; six fits Basic's 60; twenty fits Pro's 200; fifty fits Studio's 500. Thirty generations in a month is a Studio-scale habit, not a Basic one — check your count against the standard-videos column above rather than against your instinct. If it is genuinely a one-off, a pack is better value than a month of subscription you will forget to cancel.
- Buy, and note which clock you are on. Subscription credits last the billing period, yearly credits last the billing year, and pack credits never expire. Buying a pack alongside a subscription does not waste the pack — the pack waits at the back of the queue.
- Generate normally and let the expiry order do the rest. The soonest-expiring credits are always spent first, so your monthly allowance is consumed before your non-expiring packs, with no manual sorting required.

FAQ
How many credits does one video cost?
A standard 720p, 12-second video is 10 credits. The studio default of 1080p at the same 12 seconds is 30 credits. Longer clips scale the price with the duration and round up to a whole credit, and aspect ratio does not change the price at all.
Do unused credits roll over?
It depends on where they came from. Subscription credits are granted for the billing period, yearly credits last the billing year, and one-time pack credits never expire. Because the soonest-expiring credits are spent first, your monthly allowance is always consumed before your packs, so nothing lapses while longer-lived credits sit unused.
Do vertical videos cost more than widescreen ones?
No. Rendering the same clip as vertical 9:16 costs exactly what the widescreen 16:9 version costs, because the frame contains the same number of pixels. Choose the shape based on where you are posting, not on price.
What happens if a render fails?
The credits are refunded automatically to the credits they came from, with their original expiry intact. You do not need to request it, and if a balance still looks wrong you can write to contact@ozilai.video.
Are one-time packs better than a subscription?
For a single video or a one-off project, yes — the pack never expires and you are not committing to a monthly charge. Once you are generating several times a month, the subscription's lower cost per video wins by a wide margin. The pricing page lays out both side by side, and if you are comparing tools rather than plans, the generator comparison looks at what those credits buy elsewhere.
