Budget and credits
Lesson 18 of 22 in the course “AI Video, No Flops”. Free, with animations and a quiz.
What a second costs
In the last lesson we found that one good shot takes 20 or more attempts. So the price of an attempt decides everything. Video generators charge per second. Take Google’s public price list as of October 2026: Veo 3.1 at 1080p costs $0.40 per second, the fast Veo 3.1 Fast $0.12, the light Veo 3.1 Lite $0.08. Subscriptions like Higgsfield charge credits instead of dollars, but the logic is the same: a strong model costs several times more. Prices change every few months, so remember the ratio, not the numbers.
One shot on a calculator
Let’s cost one shot. Eight seconds in Veo 3.1 is 8 × $0.40 = $3.20. The same eight seconds in Veo 3.1 Lite is 8 × $0.08 = $0.64. A five-fold difference. $3.20 seems small. But remember the 20 attempts per shot: a single shot in the strong model already costs $64. And an ad has fifteen of them. That’s why pros never search for composition and motion in the most expensive model. You need the expensive model only once you already know exactly what you want.
Costing the whole video
Now the whole video: 15 shots of 8 seconds with 20 attempts each, so 300 generations. Plan A: do everything in Veo 3.1. That’s 300 × $3.20 = $960. Plan B: all 300 drafts in Lite, that’s 300 × $0.64 = $192, then regenerate only the 15 chosen shots in Veo 3.1, that’s 15 × $3.20 = $48. Total $240 versus $960, four times cheaper. And the final quality is the same, because every final shot is still made by the strong model. Note: a Lite draft and a Veo 3.1 final won’t be identical. The draft locks the idea, camera and timing, and the final from the same prompt delivers them at high quality.
The quality ladder
It helps to think of the work as a ladder where each step costs more than the last. Step one is an image: composition, product placement and outfit are checked on a still frame, which costs less than video. Step two is a low-res draft: here you look at motion and timing. Since 22 September 2026 Higgsfield has made this a separate button: Seedance 2.5 has a Draft Mode that first gives a 480p preview, and the 1080p render runs only after you approve. Step three is picking. Step four is the final in a strong model. Step five, 4K, is needed only if the video goes on a big screen. Only what passed the previous step climbs to the next.
Five ways to save
Besides the ladder, five habits cut the bill. Short drafts: Veo 3.1 lets you choose 4, 6 or 8 seconds, and if you’re testing one move, 4 seconds cost half of eight. Low resolution and fast models for every test. Check composition on an image. Save a good prompt and change one detail at a time: that way you understand exactly what worked and don’t start from scratch. And fix small defects with an edit from the previous level, not a new generation. You can write all of this into the agent’s brief once, and it will follow the rules in every task.
A monthly budget
So as not to hit zero credits by mid-month, Mira splits them up front. It’s not a law, just a handy starting ratio worth tuning to yourself. Sixty percent goes to drafts: there will be many, and they’re cheap. Twenty percent goes to finals, the chosen shots in a strong model. And twenty percent stays in reserve for client changes and surprises, because “can we see one more option?” comes up in every project. The agent sees this plan in the brief and logs how much of each part is spent. If drafts have used up their share, it warns Mira instead of dipping into the reserve.
Where to pay for quality
Not all shots matter equally. A cheap model is great for finding composition and camera, testing timing and motion, and for background and filler shots where viewers don’t look closely. A strong model is needed where the eye catches quality: face close-ups where skin and expressions show, the product up close, because that’s what we’re selling, and the first shot, which decides whether the viewer keeps watching. That way Mira spends expensive credits on three or four key shots and makes the rest cheaper, and viewers don’t notice. In the next lesson we’ll see how to assemble shots into a video that holds attention.
Check yourself
- Veo 3.1 at 1080p costs $0.40 per second. What does one attempt at an 8-second shot cost?
Correct answer: $3.20. Price is per second: 8 × $0.40 = $3.20. - Mira plans 300 attempts for a video and wants all of them in the strongest model “for quality”. What should you suggest?
Correct answer: Drafts in a cheap model, and regenerate only the chosen shots in the strong one. The strong model still makes the final, and the 285 rejected attempts cost several times less. - Mira isn’t sure where the sneaker should sit in the frame: left or centre. What’s the cheapest way to test?
Correct answer: Generate two images and compare. Composition is a single-frame question. An image answers it cheaper than any video. - In which shot of the ad is it definitely worth spending credits on the strong model?
Correct answer: The first shot: a close-up of Mira with the sneaker. A close-up of face and product, and the first one at that, is exactly where the eye sees quality and decides whether to keep watching.
