Pay Per Use AI Video: Is It Cheaper Than a Subscription?

Short answer: pay per use AI video is cheaper than a subscription for most people, because a subscription's price per second depends on how much of it you actually use, and almost nobody uses all of it. A plan only wins if you spend nearly every credit, every month. If you render in bursts, pay per use comes out well ahead.

Quick flag: Leaxor is mine, and it's pay per use. I've put the case for subscriptions in here too, because there is one.

The question isn't really "which is cheaper". It's "what does a second of video I actually keep cost me". Per-clip pricing answers that directly. A plan answers it only after you know your usage, which is why the sticker price on a pricing page tells you so little.

What a second of AI video costs, pay per use

These are Leaxor's prices per second of a silent clip, read off the same table the checkout uses. They don't change with how much you render.

That spread is the first reason pay per use works: you pick the model per shot. Draft on the cheap one, render the keeper on the good one. On a plan tied to one lab, every draft costs flagship prices. The full list of every model is in what AI video costs per clip.

What a subscription really costs per second

Runway publishes its plan clearly enough to work this out. Standard is about $12 a month billed annually for 625 credits, and Gen-4 burns about 12 credits a second. That's roughly 52 seconds of Gen-4 a month. Credits reset each month, so the real price per second depends on how much you use:

Use all of it and it's competitive with Veo 3.1 above. Use a quarter, which is a normal month for anyone who isn't publishing daily, and every second you kept cost $0.92. The pricing page shows the first row. Your bank statement shows the last one.

Two caveats so this stays fair. Gen-4 and Kling v3 aren't the same model, so this compares billing, not quality. And Runway's plan also buys its editor, which pay per use on Leaxor doesn't have. My Runway explainer covers what else the plan includes.

The break-even, in one sentence

A subscription beats pay per use only when (plan price ÷ seconds you actually use) drops below the per-second price you'd pay per clip. Against Kling v3 at $0.11 a second, Runway Standard never gets there even at full use. Against Veo 3.1 at $0.25, it wins only if you use most of the plan.

The general version: a plan pays off when your usage is high and steady. Bursty use, a big project one month and nothing the next, is where monthly resets eat the saving.

What a month costs on pay per use

The first row is where pay per use wins outright. A plan charges you the same in a quiet month. The last row is where a plan with a big allowance can start to make sense, if you'd really render that much every month and you're happy on one lab's models.

How AI video credits with no monthly fee work

This is the part people ask about most, so here's the mechanism without the marketing.

1. You buy a balance. On Leaxor credits are $0.10 each, bought 50 to 50,000 at a time.
2. Each job shows its price first. A clip is priced by its model and length, an image by its model, a finished video by its quality tier. You see the number before you press render.
3. Nothing renews. There's no monthly fee and no subscription required, so there's no reset date. Credits never expire.
4. Failures don't cost you. A render that fails is refunded automatically.

The thing to check on any tool that sells credits is whether its credits expire. Some plans' monthly credits vanish at renewal, and some top-up packs have been reported to expire after about 90 days; I covered one example in my Higgsfield explainer. An expiring credit is a subscription with extra steps.

When a subscription is the better deal

• You render every day, at a steady rate, and you'd use the whole allowance.
• You want one lab's model and its editor, and switching models doesn't matter to you.
• The plan includes something you'd pay for anyway, like an editor or team seats.

If none of those is you, you're paying for the month, not the video.

How to keep pay-per-use costs down

Paying per clip only stays cheap if the clips you pay for are ones you keep. Four habits do most of the work.

1. Draft on the cheap model. Find the framing on Seedance 1.0 Pro at $0.03 a second, then render the keeper on Kling or Veo. A draft that's wrong at $0.03 a second is a shrug; at $0.25 it's a habit you'll notice.
2. Render short, then extend. Five seconds tells you whether the motion works. Ten seconds of a shot that doesn't work costs twice as much to learn the same thing.
3. Switch sound on only when the shot needs it. On Veo 3.1 an 8-second clip goes from $2.00 silent to $3.90 with sound. On Seedance 2.5 it costs nothing extra, so that's where to make the clip that needs it.
4. Start from a still. An image costs a few cents and you can reroll it freely. Get the frame right as a picture, then animate it once with image to video. Most of my clips start that way.

None of this is a trick. It's the same reason pay per use is cheaper in the first place: you only pay for the video you decide to make.

What about "no subscription" free AI video?

Search "AI video generator no subscription" and Google mostly shows free tools with no sign-up. They're real and worth trying, with the usual catches: watermarks, low resolution, daily caps, and older models. Leaxor isn't one of them. It has no free tier, and I'd rather say so here than have you find out at checkout. The comparison that matters once you're publishing is paid per clip against paid per month, which is what this post covers.

For context on the wider picture, LTX puts AI generation at $0.50 to $50 a minute against $1,000 to $50,000 a minute for traditional production. Either billing model is cheap next to that. The difference between them is how much of your money becomes video you keep.

Every clip's price is on the affordable AI video generator page, sorted cheapest first, and the subscription tools are compared in my AI video generator pricing comparison.
