The Same Credits Cost 2.5x More on One Plan Than Another

The short version: Subscription pages sell you credits. Nobody tells you to divide the price by them. That division is the only number that compares tiers honestly, and it can save you hundreds.

Every AI video pricing page is organized the same way. The plan name, the monthly price, then a big number: credits, or videos, or both.

Almost nobody does the one division that makes those plans comparable.

cost per credit = monthly price / included credits

Do it before you compare anything else. On one real set of AI video tiers, that single number spreads by 2.5×.

The table nobody publishes

Using StoryShort's published tiers as the worked example — all figures from its pricing page:

Note the two billing columns: yearly is about 40% cheaper per month, which drops the effective cost per credit to $0.058 on Starter and $0.023 on Ultra. The ratio between tiers barely moves, which is the point — the tier choice and the billing-cycle choice are separate decisions, and the tier one matters more.

Same product, same features, same output. Credits cost two and a half times more on the entry tier than on the top tier.

And look at what that video-count column actually is: 26 videos, assuming 30-second clips at one attempt each. Change the format and the same 400 credits buys something completely different — StoryShort's own table puts an ASMR video at ~50 credits (8 videos), a UGC ad at ~115 (3 videos), and a talking-avatar video at 270+ (one video). Long-form is not available on Starter or Growth at all.

Notice what this does to a specific job. Take a workflow that consumes 135 credits — one minute of Basic-quality AI drama:

The identical video costs $13.20 or $5.40 depending on which plan you bought. Nothing about the output differs.

Why the advertised video count is the least useful number

Plans advertise videos, not credits, because video counts are bigger and friendlier. But that number is derived from credits at an assumed usage rate — and it assumes each video consumes exactly the credits of one clean attempt.

You do not publish clean attempts. You publish the survivor of several.

Which means the advertised count is not a quantity of published videos. It is a quantity of generations. In practice, plans advertising forty videos produce somewhere around fifteen to twenty-five, depending on how disciplined your workflow is.

So the honest comparison of two plans is not "40 videos vs 120 videos." It is:

(price / cost per credit) / your real attempts per published video

Two plans can advertise very different video counts while delivering nearly the same number of publishable videos. The price is what differs.

The tiers do not differ in quality

This is the part that surprises people: on most of these products, higher tiers do not unlock better output. They unlock more output and a few organizational features — more series slots, higher concurrency, brand presets, sometimes API access.

The generation quality on Starter is the same as on Ultra. There is no "our good model" reserved for the expensive plan.

That changes the buying decision completely. You are not choosing a quality level. You are choosing a wholesale rate, and buying in bulk is only a discount if you consume the bulk.

How to actually pick a tier

Step 1 — Measure your consumption. Publish five videos and count the credits each one cost you from first generation to final export. That is your true per-video cost, and it is the only input that matters. Most people have never measured it.

Step 2 — Multiply by your real monthly volume. Not your intended volume. The number you actually published last month, or a realistic estimate if you have not started. Intention is not a plan.

Step 3 — Compare total cost, not unit price. If your volume fits in the entry tier, the entry tier is cheaper in total even though each credit costs more. Buying Ultra at $199 to chase a lower unit rate while publishing three videos a month is a five-fold increase in spending to save pennies per credit.

Step 4 — Check the rollover cap before buying big. StoryShort rolls unused credits over, capped at twice your monthly allowance. That means you cannot bank a large balance for a future project, so "buy a big plan and let credits pile up" does not work.

Step 5 — Only then consider the higher tier. It wins for exactly one profile: someone consuming most of their allowance every month, every month.

Where the higher tier genuinely wins

Be fair to it, because the math does favor volume:

• You are publishing daily or near-daily
• You are running more than one channel or series
• You are producing long-form or short drama, where per-episode consumption is much

higher than a standard short

• You consistently exhaust your credits before the period ends

If three of those four apply, the expensive plan is the cheap one. If one applies, you are buying a discount you will not use.

The bottom line

Pricing pages sell credits and advertise videos, because both numbers sound generous. Neither is comparable across tiers until you divide.

Cost per credit is the number. Your measured attempts per published video is the multiplier. Multiply them by your actual volume and the tier decision makes itself.

Two people can buy the same subscription and pay 2.5× different rates for identical output. The only difference is whether they did one division first.
