Generative video is not like that. Every button press spends money, and the interface deliberately does not show you money, it shows you credits.\n\nList prices in 2026 run from about five cents per generated second for budget models to around seventy cents for premium models at 1080p (checked October 2026), depending on model, resolution and tier. That range moves constantly; check the current page rather than trusting the number here.\n\nThe figure that actually matters is not price per second. It is price per **usable** second. At a one-in-six hit rate (normal once a shot has a specific requirement) an eight-second clip listed at two dollars cost twelve, plus an hour of your attention. A thirty-shot piece at that rate is a real invoice, and people discover this at shot nineteen.\n\n## Credits are not money, and that is the point\n\nEvery platform prices in credits. Different models and resolutions cost different credits per second. Credits usually expire at the end of the billing month. Aggregators add a margin on top of the underlying model's price.\n\nNone of this is dishonest, but all of it puts distance between the click and the cost. So close the distance manually, once: work out what a single eight-second 1080p generation on your chosen model costs in your own currency. Write it on paper and put it next to the screen. That one number changes behaviour more than any advice in this lesson.\n\n## A discipline that keeps the bill survivable\n\n1. **Shot list first.** You cannot batch what you have not planned, and unplanned generation is where budgets die.\n2. **Draft pass at the cheapest setting.** Lowest resolution, shortest duration, fastest model or explicit turbo tier. At this stage you are testing whether a motion idea works, not making the shot. A draft that costs a tenth of a final tells you nine times as much per rupee.\n3. **Fix the still, not the prompt.** Regenerating a still costs on the order of one per cent of regenerating a clip. Almost every failure has a cheaper diagnosis one step upstream.\n4. **Set a kill number before you start.** Three attempts per shot. On the fourth you are not allowed to generate again: you change the still, change the shot, or cut it from the list. Without a kill number, one stubborn shot quietly eats the budget for eight others, and it is always a shot that did not matter.\n5. **Batch.** Queue every shot at once instead of watching each one render. You make better decisions reviewing eight results together than one at a time, and it breaks the drip of just-one-more that is how afternoons disappear.\n6. **Final pass at full quality on the chosen take only.** Same still, same prompt, same seed where the tool allows it.\n\n## Subscription against pay-as-you-go\n\nA subscription is cheaper per second if you finish a project inside the billing month, and worse than useless if you do not, because unused credits generally expire rather than roll over. Pay-as-you-go top-ups, through the platforms themselves or through fal.ai and Replicate, cost more per second and nothing at all in a month where you are not working.\n\nFor a student, or anyone with irregular work, top-up is usually the honest choice. Read the rollover terms before subscribing; most do not roll over, and the ones that do usually cap it.\n\n## The free path, and what it costs instead\n\nFree daily allowances on hosted tools, Hugging Face Spaces, and Colab or Kaggle GPU sessions cost nothing in money. They cost queue time and session limits, and a free session that dies at eighty per cent through a render is a real loss of an hour.\n\nUse them for learning and for your own work without hesitation. Do not promise a client a deadline that depends on somebody else's free queue.\n\n## Quoting client work\n\nQuote generation as a line item, and quote it in shots rather than in hours. Something like: thirty shots, up to four attempts included per shot, further revisions billed per shot.\n\nThat sentence exists to protect you from the client who asks for the twelfth version of shot nine without knowing that each version costs money. Hourly rates hide the cost driver from both of you. Per-shot pricing puts it where the client can see it and make a choice.\n\n---\n\nToday: open your tool's pricing page and work out, in your own currency, what one eight-second 1080p generation costs. Multiply by six. That is your real cost per delivered shot, and it is the number your quote has to be built on."},"check":{"question":"A freelancer quotes a thirty-shot AI video by the hour and finishes sixty per cent over budget, having spent most of the overage on two shots the client kept revising.
