persecond
AI video priced by the second, not by the month.
Every AI video service sells you a monthly plan and credits that expire. The models underneath cost cents. persecond charges you for the seconds you actually generate — and shows you the bill for every single clip.
What it costs
What $15 actually buys, and what happens to it at the end of the month.
| For $15 | Video you get | At month end |
|---|---|---|
| Runway Standard | ~52 seconds | credits reset |
| Kling, Pika · entry plans | a monthly allowance | credits reset |
| persecond · standard model | 75 seconds | stays yours |
| persecond · draft model | 150 seconds | stays yours |
A 5-second clip costs $0.50 on the draft model and $1.00 on the standard one, sound included from $1.25. The price is on screen before you press generate.
You top up once and spend it as you go. Nothing renews, nothing expires, and if a generation fails you are not charged for it. Spread $50 over three months and you have paid $50 — not three monthly plans.
One character, three shots
Three separate generations, nothing touched up afterwards. The robot is the same in all of them because its description is repeated word for word in every prompt — which is the whole trick, and the thing most tools leave you to do by hand.
All three cost $1.20 together. On a monthly plan elsewhere you would have paid for the month.
Built for people making series, not single clips
The hard part of AI video is not one good shot. It is the second episode looking like the first.
Characters that stay the same
Models remember nothing between generations. Give a character a written canon once, and it goes into every prompt word for word — which is the only thing that actually keeps a face recognisable across episodes.
A minute, not eight seconds
No model gives you a full minute in one go. Describe the idea, get a storyboard cut to your model’s real limit, edit any shot by hand, then shoot and stitch it into one file. Each shot can start from the last frame of the one before.
Edit footage you already have
Change clothing, props or background on an existing clip while movement, timing and faces stay put. Attach a reference photo and the model uses that exact item, not its idea of your description.
Nine models, one catalogue
Iterate on a two-cent draft model, render the final on the good one. Prices are shown per second next to every model, and the aspect ratios are labelled by where the video is going — TikTok, Reels, Shorts.
Every version kept
The original is never overwritten. Each run is a new version beside it, stored with the prompt, the model and the price. Switch between before and after, or go back to version two a month later.
A bill you can read
Every clip is logged with what it cost. Filter by series and see what an episode ran you. No credit arithmetic, no guessing where the month went.
Questions
Do my credits expire?
No. Money you put in stays until you spend it. That is the whole reason this exists — expiring credits are how everyone else gets paid for video you never made.
What if a generation fails?
You are not charged. The amount is reserved when the job starts and released in full if it does not finish. You only pay for video you actually receive.
Can I get a refund?
Yes. Write to us and we refund your unused balance, no questions and no conditions. See the refund policy.
Can I use the videos commercially?
The output is yours. Terms of the underlying model providers still apply to what you generate, and those differ between models — the catalogue names which model made each clip.
Is there a free trial?
No trial and no card on file. The smallest top-up is $10, which is about twenty draft clips — enough to decide.
