How AI Video Pricing Works: 3 Models Compared (2026).

AI video pricing breaks into three shapes: per-second API billing, per-credit subscriptions, and flat monthly tiers. The cheapest one depends entirely on how much finished video you actually use in a month. Google's Veo 3.1 API charges $0.05 to $0.40 per second depending on speed and resolution; Runway's cheapest credit subscription is $12–$15/month for 625 credits; flat-tier plans charge one price for a capped number of generations and never show the per-render cost at all.

How does per-second AI video pricing work?

Per-second pricing is metered API billing: you pay only for finished output, priced by resolution and generation speed, with no monthly minimum. On Google's Gemini API, Veo 3.1 Lite runs $0.05/sec at 720p, Fast runs $0.10–$0.12/sec, and Standard runs $0.40/sec at 720p or 1080p — audio is included in the price rather than billed separately. An 8-second Standard clip costs $3.20; the same length on Lite costs $0.40. This model rewards anyone who can predict usage precisely and is comfortable integrating directly against an API — but it needs a cloud billing account and gives no bundled allotment, so a slow month and a busy month cost exactly proportional amounts.

How does per-credit subscription pricing work?

Per-credit pricing sells a monthly credit pool at a fixed price; every render debits credits by length and resolution, and unused credits typically expire at the end of the cycle. This is what most consumer AI video apps use, including Runway and getvivix — what differs is what the pool actually buys:

Why do flat-tier subscriptions hide the real cost?

A flat-tier subscription charges one fixed price for a capped number of generations and never displays a per-render number anywhere — you have to find the real cost yourself by dividing. ChatGPT Plus used to bundle Sora video generation into its flat monthly plan before OpenAI discontinued the consumer Sora app on April 26, 2026 (full, sourced timeline in our Sora alternatives post). Take a hypothetical $20-a-month flat plan as an example: divided across 50 finished generations that's $0.40 each; across 10 renders it's $2.00 each; used zero times, it's $20 for nothing. The headline price never moves — only your own usage log tells you what you actually paid per clip, which is why flat tiers reward light, occasional use and quietly punish an inconsistent month.

How to do this on getvivix

See the credit cost before every render instead of estimating it after the bill:

1. Sign up free — 3 credits on signup plus 3 more every day, no card required.
2. Open Create and pick any model — the exact credit cost shows on the card before you click generate.
3. Render, then check the debit on /history so you know your real per-clip number.
4. Compare that number against 1,000 credits a month for $10 before you upgrade.

Skip a shared-credit plan if you already run enterprise-scale volume on one model through a direct provider API — dedicated per-second billing can beat a shared pool at that scale. Otherwise, seeing the real cost before you spend is the point.

FAQ

What's the cheapest way to pay for AI video?

Per-second API billing wins at very low, occasional volume — Veo 3.1 Lite starts at $0.05/sec with no subscription required. For regular use across multiple models, a shared-credit subscription usually beats paying per second against one dedicated API.

Do unused AI video credits roll over to the next month?

Not on getvivix. Subscription credits last one 30-day window from the day you subscribe and don't carry into the next cycle — re-subscribing resets the pool to the full amount rather than adding to what's left.

How much does AI video actually cost per second?

It depends on the provider and resolution. Google's Veo 3.1 API ranges from $0.05/sec (Lite, 720p) to $0.40/sec (Standard, 720p or 1080p) — an 8-second clip runs $0.40 to $3.20 depending on which tier you pick.

Do I need a credit card to test real AI video pricing?

No. getvivix's free tier gives 3 credits on signup plus 3 more every day, no card required, so you can see the exact credit cost of a render before paying anything.

Are failed AI video generations refunded?

On getvivix, yes — if a render errors out before finishing, the credit deduction reverses automatically. Refund policies vary a lot by provider, so check the specific terms before assuming the same applies anywhere else.

AI video pricing is only ever three shapes — per-second, per-credit, and flat-tier — and the cheapest one depends on your real monthly usage, not the sticker price a provider puts on its homepage.
