How billing works: credits, not seconds
Gemini Omni Flash is billed in credits. Every generation shows its cost before you run it, and the cost depends on only three things: the clip length, the resolution, and whether you attach a source video to edit. Prompt length, number of reference images and how many times you have used the tool do not change the price.
Credits come from three places. The free account grant is the starting point. Monthly or yearly plans add a pool of credits that refreshes every billing cycle. One-time credit packs add credits that never expire. You can mix them, and the workspace spends whatever balance you have.
Credits per clip, by length and resolution
The table is calculated from the configuration the generator charges from, so it matches what you will actually be charged. 720p and 1080p cost the same. 4K costs more because it is a larger render.
| Clip length | 720p or 1080p | 4K |
|---|---|---|
| 4 seconds | 90 credits | 210 credits |
| 6 seconds | 120 credits | 240 credits |
| 8 seconds | 150 credits | 270 credits |
| 10 seconds | 180 credits | 300 credits |
What editing an existing video costs
When you attach a source video, the workspace switches to editing and the price is flat: 240 credits at 720p or 1080p and 360 credits at 4K, whatever clip length you select. Editing costs more than a short generated draft because the model has to follow the footage you provide, so it is worth getting the prompt right on a cheap draft first.
What the free start gets you
Creating an account grants 300 credits and does not ask for a credit card. A daily check-in adds 5 more credits whenever you come back. In practice that is 2 clips at the default 6-second length, or 3 clips at 4 seconds, or one edit of an existing video at 1080p. It is enough to judge whether the output quality fits your work before you spend anything.
What a credit costs in dollars
Credits are sold in one-time packs and through monthly or yearly plans. The packs below are read live from the pricing catalog, so the figures are always current. The last column converts each pack into the price of one default 6-second 1080p clip. Plans, which bundle credits at a different rate and include a commercial license, are listed on the pricing page.
| Pack | Price | Credits | Per 6 s 1080p clip |
|---|---|---|---|
| Starter | $5 | 250 | $2.40 |
| Pack 1 | $20 | 1,000 | $2.40 |
| Pack 2 | $50 | 2,575 | $2.33 |
| Pack 3 | $100 | 5,250 | $2.29 |
Plan or credit pack: which fits
Choose a one-time credit pack when your use is occasional or tied to a single project. The credits never expire, there is nothing to cancel, and you only buy again when you run out. Choose a monthly or yearly plan when you generate every week: plan credits refresh each billing cycle, the plans carry a commercial license, and you can cancel at any time. Yearly billing is offered on the plans and is shown with its saving on the pricing page.
If you are unsure, start with the free credits, run the kind of clip you would actually publish, and look at how many credits it used. Multiply that by how many clips you expect to make in a month and compare the result with the pack and plan sizes on the pricing page. That one number answers the question better than any rule of thumb.
Three budget examples
Credits are easier to judge against a real project than in the abstract. These examples use the figures from the table above.
- Concept test: three 4-second drafts at 720p or 1080p cost 270 credits in total.
- Short social video: five 6-second shots at 1080p cost 600 credits. Add three 4-second drafts first and the whole project costs 870 credits.
- Same video in 4K: five 6-second shots cost 1200 credits, so reserve 4K for the shots that will actually be shown large.
Ways to spend fewer credits
The biggest saving is drafting short. A 4-second clip costs less than a 10-second clip, so test the prompt there and render the long version once. The second saving is changing one variable per attempt, which stops you paying for rerolls that taught you nothing. The third is using reference images for anything that is hard to describe, because a reference removes guesswork that would otherwise cost several attempts.
You are never charged for a generation that fails. Credits from a failed generation are returned to your balance automatically. Subscription credits refresh each billing cycle and expire if unused, while one-time pack credits never expire, so a pack suits occasional use and a plan suits steady use.
