How Much Does an AI Video Generator Cost?
As of 28 October 2026, an AI video generator costs anywhere from about $0.50 for a single 5-second clip on a budget model to $90+ per month on a heavy subscription plan. Most tools charge through one of four models: per-second pricing, per-clip pricing, monthly credit subscriptions, or one-time credit packs. On Kenerate AI, a 5-second 720p draft starts at 150 credits (about $1.50) on Wan 3.0, and credits come from one-time packs starting at $15 — so you only pay for what you actually render.
This guide breaks down every pricing model, shows real per-second prices, and walks through worked examples so you can budget before you generate.
Do you have to pay for an AI video generator?
Usually yes — at least for anything beyond a short trial. Video generation is the most compute-hungry thing consumer AI does, so genuinely unlimited free video doesn't exist. What "free" actually looks like in practice:
- One-time trial credits. Runway's free plan gives 125 credits once, which covers roughly 10 seconds of its Gen-4.5 model, and outputs carry a watermark (Runway pricing, checked 28 October 2026).
- Small daily allowances. Kling AI gives logged-in users 66 free credits a day that expire after 24 hours (eesel.ai Kling pricing guide, 2026).
- Free image tools, paid video. On Kenerate AI, image generation is available on the free tier, while video unlocks with any one-time credit pack — there's no recurring subscription required.
So the honest answer to "are AI video generators free?" is: you can test one free, but producing videos regularly costs money everywhere. The real question is which pricing model wastes the least of it.
What are the four ways AI video generators charge?
| Pricing model | How it works | Typical examples | Best for |
|---|---|---|---|
| Per-second (credits) | Each second of output burns credits; rate depends on model + resolution | Kenerate AI, most API providers | Paying only for what you render |
| Per-clip | Fixed price per 5s/8s/10s clip regardless of content | Pixverse-style clip pricing | Predictable short-form budgets |
| Monthly subscription | Fixed fee, credits refresh monthly (and usually expire) | Runway, Kling, Hailuo | Steady, high-volume output |
| One-time credit packs | Buy credits once, they never expire | Kenerate AI | Occasional or bursty creators |
The subscription trap is expiry: on Runway, Standard and Pro credits refresh monthly without rollover, and Kling subscription credits expire at the end of each billing month. If you skip a month of creating, that money is gone. One-time packs sidestep this — Kenerate credits never expire, so a $15 pack from January still works in December.
How much does AI video cost per second?
Per-second pricing is the easiest way to compare tools, because it strips away the credit-math marketing. Here's what public API pricing looked like in 2026, per the AtlasCloud API price comparison (updated 28 February 2026):
- Seedance 2.0 Fast: $0.09/second at 1080p
- Vidu Q3: $0.07/second at 1080p
- Hailuo 2.3: $0.10/second at 1080p
- Sora 2 (API): $0.10/second at 720p; Sora 2 Pro $0.30/second at 720p (CometAPI, verified May 2026)
- Kling 3.0: roughly $0.13–0.15/second at 1080p
On Kenerate AI, credits map to roughly $0.01 each (a custom pack is $10 per 1,000 credits), which makes per-second costs easy to read. These are the live rates from the app as of 28 October 2026:
| Model (on Kenerate) | 480p | 720p | 1080p | 4K |
|---|---|---|---|---|
| MiniMax H3 | 10 cr/s | — | — (768p: 20 cr/s) | — |
| Wan 3.0 | 15 cr/s | 30 cr/s | 60 cr/s | — |
| Seedance 2.0 Mini | 18 cr/s | 36 cr/s | 90 cr/s | 180 cr/s |
| Ken 1 | 15 cr/s | — (768p: 37.5 cr/s) | 75 cr/s | — |
| Veo 3.1 Fast (with sound) | — | 45 cr/s | 45 cr/s | 90 cr/s |
| Seedance 2.0 | 36 cr/s | 72 cr/s | 180 cr/s | 360 cr/s |
| Sora 2 Pro | — | 90 cr/s | 150–210 cr/s | — |
| Seedance 2.5 | 54 cr/s | 108 cr/s | 270 cr/s | 540 cr/s |
| Veo 3.1 (with sound) | — | 120 cr/s | 120 cr/s | 180 cr/s |
Two things jump out. First, resolution is the biggest cost lever — 1080p typically costs 2–2.5× the 720p rate on the same model. Second, the spread between models is enormous: a second of MiniMax H3 at 480p (10 credits ≈ $0.10) costs 12× less than a second of Veo 3.1 with sound (120 credits ≈ $1.20).
What does a single AI video actually cost? (worked examples)
Numbers per second are abstract; clips are what you pay for. Here are real worked examples at Kenerate's rates (1 credit ≈ $0.01 on a custom pack):
Example 1 — a cheap 5-second 720p draft. Wan 3.0 at 720p costs 30 credits/second. A 5-second draft = 5 × 30 = 150 credits, about $1.50. Drop to 480p and it's 75 credits — about $0.75 — which is the smart way to iterate on prompts before committing to a high-res render.
Example 2 — a 10-second 1080p final. Wan 3.0 at 1080p costs 60 credits/second, so 10 seconds = 600 credits, about $6.00. The same 10 seconds on Seedance 2.5 at 1080p (270 cr/s) = 2,700 credits, about $27 — the premium buys stronger physics, multi-shot direction and native audio, but you should reserve it for keepers, not drafts.
Example 3 — an 8-second clip with sound. Veo 3.1 Fast with audio runs 45 credits/second: 8 seconds = 360 credits, about $3.60. Full Veo 3.1 at 120 cr/s makes the same clip 960 credits (~$9.60) — nearly 3× more for the flagship tier.
The draft-then-upscale trick. The cheapest workflow isn't picking one model — it's drafting at 480p, picking the best take, and running it through an AI video upscaler to 1080p or 4K. Three 480p Wan 3.0 drafts (225 credits) plus one upscale usually costs less than a single 1080p generation on a premium model, and you got three takes instead of one.
How much do AI video subscriptions cost per month?
If you'd rather pay monthly, here's what the major subscription tools charged in 2026:
| Tool | Entry plan | Mid plan | Top plan | Credits expire? |
|---|---|---|---|---|
| Runway | $15/mo — 625 credits | $35/mo — 2,250 credits | $95/mo — 9,500 credits | Yes (Max rolls over one cycle) |
| Kling AI | ~$10/mo — 660 credits | $37/mo — 3,000 credits | $92/mo — 8,000 credits | Yes, monthly |
| Kenerate AI | $15 once — 1,300 credits | $49 once — 4,800 credits | $199 once — 20,000 credits | Never |
Sources: Runway pricing and eesel.ai's Kling guide, both checked 28 October 2026; Kenerate prices from kenerateai.com/app/pricing. Across the category, Costbench's 2026 benchmark puts the median spend near $62/month for AI video tools — so if you're budgeting for regular production, $30–90/month is the realistic range on subscriptions.
Note the structural difference in that table: Runway and Kling are monthly fees that reset, while Kenerate packs are one-time purchases. $15 on Runway buys you 625 credits that vanish in 30 days; $15 on Kenerate buys 1,300 credits that sit in your account until you use them. For anyone who creates in bursts — a campaign this month, nothing next month — expiry is the hidden cost that never shows up on the pricing page.

What makes an AI video cost more or less?
Five variables move the price on almost every platform:
- Resolution. The steepest multiplier. On Kenerate, Seedance 2.5 goes from 54 cr/s at 480p to 540 cr/s at 4K — a flat 10× jump.
- Duration. Cost scales linearly with seconds on per-second models. A 30-second Wan 3.0 clip at 720p is 900 credits; the same money buys six 5-second drafts.
- Model tier. Flagship models (Veo 3.1, Sora 2 Pro, Seedance 2.5) cost 3–12× more per second than value models (MiniMax H3, Wan 3.0) on the same platform.
- Audio. Sound isn't always free: Veo 3.1 with audio is 120 cr/s versus 60 cr/s silent on Kenerate. If you're adding your own soundtrack anyway, generate silent.
- Inputs. Reference-heavy generations can bill for the reference media too — on Kenerate, Wan 3.0 reference mode bills attached clip seconds on top of output seconds. Starting from a single image with image-to-video keeps the bill tied to output length only.
How do you budget for AI video without overspending?
A practical routine that works on any per-second platform:
- Write the prompt once, carefully. Bad prompts are the biggest hidden cost — every re-roll is a full-price render.
- Draft at the lowest resolution. 480p shows you motion, composition and prompt-adherence for a quarter of the 1080p price.
- Generate short. Test at 5 seconds even if the final will be 15. Most prompt failures are visible in the first two seconds.
- Pick one take, then scale. Re-render the winner at final resolution and length, or upscale the draft directly.
- Track what each model costs you per usable second. A cheap model you re-roll five times costs more than a premium model that nails it twice.
On Kenerate, every model shows its exact credit price before you hit generate, so there are no surprise charges — the price you see on the button is the price you pay.
Frequently asked questions
Does an AI video generator cost money? For meaningful use, yes. Free tiers exist (Runway gives 125 one-time credits; Kling gives 66 daily credits) but they're trials, not production capacity. Expect to pay from roughly $10–15 to get started.
How much does 1 minute of AI video cost?
At 2026 rates, roughly $3.50 to $70+ depending on model and resolution. Sixty seconds on Wan 3.0 at 480p is about 900 credits ($9) on Kenerate; the same minute on Veo 3.1 with sound would be about 7,200 credits ($72). Most platforms cap single generations at 8–30 seconds, so a minute is stitched from multiple clips.
What's the cheapest way to make AI videos? Draft at 480p on a value model (MiniMax H3 at 10 cr/s or Wan 3.0 at 15 cr/s on Kenerate), then upscale only the keeper. Avoid subscriptions if you create irregularly — expiring credits are wasted money.
Why do AI video generators use credits instead of dollars? Credits let one balance price many models with very different compute costs — a 480p draft and a 4K cinematic clip can't cost the same. The catch is comparability: always convert credits back to dollars (price of pack ÷ credits) before comparing tools.
Is a subscription or a credit pack better value? Subscriptions win if you reliably use the full allowance every month. One-time packs win if your output varies — Kenerate's packs never expire, so unused credits carry over indefinitely instead of resetting.
How much does 4K AI video cost? It's premium territory: Seedance 2.5 at 4K runs 540 credits/second (~$5.40/s) on Kenerate, and Veo 3.1 at 4K runs 180 cr/s with sound. The cheaper route is generating at 720p–1080p and upscaling to 4K.
Do AI video credits expire? On most subscriptions, yes — Runway Standard/Pro and Kling credits reset monthly without rollover. On Kenerate, credits are one-time purchases that never expire.
Why is AI video so much more expensive than AI images? A 5-second clip at 24fps is 120 frames that must stay temporally consistent, plus motion modeling and often audio — orders of magnitude more compute than one image. That's why an image costs ~8 credits on Kenerate while a video starts around 50–150.
The bottom line
As of October 2026, budget about $0.50–$2 per 5-second draft, $5–$30 per polished 10-second 1080p clip, and $15–$100/month if you produce regularly — with the exact number driven far more by resolution and model tier than by which platform you pick. The cheapest workflow everywhere is the same: draft low, pick the winner, upscale once.
