What an AI Video Actually Costs (A Per-Second Breakdown)
An AI video costs anywhere from about one cent to forty cents per finished second, depending on the tool, the resolution and, above all, whether you use the plan you pay for. Talking-photo subscriptions work out to $0.010–$0.030 per second only if you use every minute; a TalkPix talking photo costs $0.053–$0.100 per second at 720p with no monthly fee; and Google's Veo 3.1 costs $0.05 (Lite, 720p) to $0.40 (Standard) per second through its own API.
Nobody advertises the price of an AI video. They advertise the price of a month.
That one distinction is why this category is so hard to shop for. You want to know what a thirty-second product clip costs. What you get shown is $29/month for "600 credits", where a credit maps to seconds at a ratio buried three clicks deep in a docs page. So you cannot compare two tools without doing arithmetic that neither of them wants you to do.
Here is the arithmetic.
The only unit that matters is a second of finished video
Every generative video tool bills, underneath, on GPU time. GPU time tracks output duration and resolution. Everything above that layer — plans, tiers, credits, "minutes" — is packaging on top of those two numbers.
So the useful question is never "what's the monthly fee". It is:
What does one second of delivered video, at the resolution I actually need, cost me?
Three things change that answer, and only one of them tends to get advertised.
Resolution. 1080p costs meaningfully more to generate than 480p — often two to three times. A plan quoted at its cheapest rate is quoting you its 480p second, not the one you will ship.
Whether unused allowance rolls over. A monthly credit bucket that resets is a use-it-or-lose-it coupon. If you create in bursts — and most people do — you are paying full price for the months you produced nothing.
What happens to a failed render. Safety filters, unusable inputs, provider errors. Failures are a normal percentage of any generative pipeline. Ask what happens to the credits, and treat a vague answer as a no.
Working the two pricing models against each other
Take a realistic year for someone making product clips: six months where you make four videos, six months where you make none. That is twenty-four videos at roughly twenty seconds each — 480 seconds of finished video.
On a $29/month subscription, twelve months costs $348 whether you render or not. The six idle months cost $174 and produce nothing. You can dodge that by cancelling and resubscribing, but that means re-onboarding four times a year, and almost nobody sustains it.
On pay-per-render, the same 480 seconds costs whatever 480 seconds costs, and the idle months are free.
Put real numbers on three workloads, using a $29-a-month plan and TalkPix's one-time packs at 720p (1 credit per second):
| Your year | $29/month subscription | TalkPix, pay once |
|---|---|---|
| Bursty: 24 videos × 20 s (480 s) | $348 — $0.73 per delivered second | $50 Pro pack (800 credits; 320 left, never expire) |
| Steady: 4 videos × 20 s every month (960 s) | $348 — $0.36 per delivered second | $100 Studio pack (1,800 credits; 840 left) |
| Heavy: about 2 minutes every week (6,240 s) | $348 — $0.056 per delivered second | about $350 in packs |
The break-even is simple: if you render less often than the subscription's monthly allowance assumes, the subscription is the worse deal — and the gap widens the more irregular you are.
The reverse is just as true, and worth saying plainly: if you genuinely render every week, a subscription usually wins. Volume is exactly what bulk pricing is for. The mistake is not choosing a subscription — it is choosing one for a seasonal workload.
How does TalkPix price a video?
TalkPix bills per rendered second, with a multiplier for resolution, and shows you the exact credit total before the render starts. Eligible new customers can get their first Talking Photo (typed script, up to twenty seconds at 720p) for $1.99, where that checkout is offered. After that, one-time credit packs run from $5 to $200, and purchased credits never expire. Credits reserved for a render that fails before delivery are returned automatically. There is no subscription: you buy a pack when you need one.
We are obviously not a neutral party here, so treat that as disclosed rather than impartial — every number above is checkable on the pricing page in about thirty seconds.
If you would rather run the numbers on your own project than take ours, the AI video cost calculator takes a length and a resolution and gives you the total.
Why is there no free tier?
Because renders cost real GPU money, and a free tier has to be paid for by something. In a subscription business it is paid for by the subscribers — which is a coherent model, and it is why most tools in this category have both. In a pay-once business there is nothing to subsidise it with.
We did try. A three-second watermarked preview shipped, sixty-six people signed up while it was live, and not one of them claimed it. So it was removed, and the $1.99 first video exists in its place: the real file, at full length, in HD, rather than a teaser. It is a smaller promise and a more honest one.
The three questions to ask any AI video tool
Whatever you end up using — and there are good tools in this category that are not ours:
"What does one second of 1080p cost me, all in?" If answering that needs a conversion table, do the conversion up front, not after the charge.
"What happens to unused allowance at the end of the month?" Rollover or expiry. There is no third answer, and only one of them is in your favour.
"What happens to my credits when a render fails?" A tool that has not thought about the refund path has not thought hard about the failure path either, and you will meet the failure path.
A tool that answers all three plainly is telling you something real about how it is run — separately from what it charges.
Where to go next
If you want the shortest possible version of this: work out roughly how many seconds of video you will actually ship in a year, multiply by the per-second rate at the resolution you need, and compare that to twelve months of the subscription. The answer is usually not close, in one direction or the other.
Then start with whichever model matches how you actually work — make a talking photo if that is the shape of your project, or turn a product photo into a video ad if you are selling something.
