Cheapest AI Porn Video Per Second in 2026
Video tiles look expensive next to stills because you pay for motion, length and often sound. The useful metric is cost per second of keepable clip, not the headline plan price. This article shows the formula, worked examples from published prices, and when a “cheap” plan is actually costly. You must be 18 or older to use any of these services.
Why cost per second beats cost per clip
A 7-second template and a 30-second Duo scene are not the same product. Comparing them by total Coin price hides that longer clips can be cheaper per second. Subscriptions that “include video” are worse still: you only know the unit cost after you divide the fee by the seconds you actually keep. For the stills version of this math, see our cost per image calculated guide. For which tools emphasise video, start with the best AI porn video generators list.
You need three inputs every time: what you paid, how many credits that bought, and how many credits one successful second (or whole clip) costs.
The formula
- Price of the pack or plan in your currency.
- Credits in that purchase (Coins, Gems, tokens or dreamcoins).
- Credits for the clip, plus the clip length in seconds.
Then:
- Cost per credit = price ÷ credits.
- Cost per clip = cost per credit × credits for that clip.
- Cost per second = cost per clip ÷ length in seconds.
- Or: cost per second = cost per credit × (credits per clip ÷ seconds).
Count only keepable seconds after your usual retry rate. If one in three renders fails, multiply the unit cost by 1.5. Mark anything missing from an official page as [unverified] and re-check at checkout.
Worked example: GeneratePorn.ai templates
GeneratePorn.ai prints Coin prices on each tile and sells one-time packs. Facts below were checked on its official site on 4 November 2026; confirm live numbers before you buy. Full pack and tile notes sit on our GeneratePorn.ai pricing page and in the GeneratePorn.ai review.
Published packs (card):
- 150 Coins for $9.99 (~$0.067 per Coin)
- 730 Coins for $39.99 (~$0.055 per Coin, labelled best rate)
- 3,310 Coins for $149.99 (~$0.045 per Coin)
Published video-related tile costs:
- Short template clips: from 21 Coins
- Most 7-second templates with sound: 79 Coins
- Undress photo turned into a 5-second video: 24 Coins (first undress free as a still)
- Duo: 79 Coins for 7 seconds, 119 for 15 seconds, 219 for 30 seconds
- Movies (multi-scene): from 119 Coins
Using the 730-Coin pack rate (~$0.055 per Coin):
- A 7-second, 79-Coin template ≈ $4.33 per clip ≈ $0.62 per second.
- A 5-second undress video at 24 Coins ≈ $1.31 per clip ≈ $0.26 per second.
- Duo at 15 seconds (119 Coins) ≈ $6.52 per clip ≈ $0.43 per second.
- Duo at 30 seconds (219 Coins) ≈ $12.00 per clip ≈ $0.40 per second.
On the smaller 150-Coin pack the same 79-Coin template rises to about $5.26 (~$0.75/s). On the largest pack it falls to about $3.58 (~$0.51/s). Crypto payments that add 25% more Coins lower the effective rate further after network fees; see paying with crypto.
Among published tile prices, the cheapest per-second path is usually a short, simple clip (from 21 Coins) or the 5-second undress-to-video route, not the longest Duo scene. Longer Duo clips improve the per-second number versus a 7-second template, but the absolute spend is higher.
Subscriptions that “include video”
Promptchan Pro
Promptchan’s official upgrade page lists Pro at $33.99 every 28 days with 800 Gems plus unlimited casual generations; video, extend and voice sit on Pro only. Per-second Gem costs for video were not published on the pages we read, so a precise cost per second stays [unverified] until you check inside the account. If you treat Pro as a flat fee and keep 60 seconds of usable video in a cycle, that is about $0.57/s before Gem overages. At 180 keepable seconds it drops near $0.19/s. Light users who buy Pro only for a few clips will pay far more per second than a Coin-based template. Details: Promptchan pricing.
OurDream, Xotic, Lovescape, Candy
OurDream lists $19.99 monthly or $9.99/month on yearly billing with video in the product mix, but dreamcoin costs per second were not clear on public pages [unverified]. Xotic’s homepage lists a plan from $9.99/month with video access; per-clip prices were not shown to us [unverified]. Lovescape and Candy AI companion plans share tokens across chat and media, so third-party dollar figures for “a video” remain [unverified] and are a poor basis for cost-per-second if chat uses most of the allowance. Treat those as flat access costs until the live UI shows a tile price.
Venice.ai credits
Venice Pro is listed at $18 with heavy image caps, plus credit pricing where 100 credits equal $1 for some video routes. Without a published credits-per-second figure for adult-capable routes, the per-second number stays [unverified]. See the Venice.ai review.
What makes a “cheap” clip expensive
- Retries. Free-form text-to-video fails more than templates. Prefer templates first; the how to make AI videos guide covers that workflow.
- Resolution and length upsells. Cost scales with seconds and resolution. Start short and low-res, then re-render winners.
- Mixing video into an image budget. A 79-Coin template is several undress edits. Keep separate budgets, as noted in the cost-per-image article.
- 28-day billing. Thirteen Promptchan cycles a year raise the annual total. See are annual plans worth it.
- Refunds. Strict windows turn a failed first batch into a sunk cost. Compare refund policies.
A fair way to compare two video tools
- Fix the output: same length band (for example ~7 seconds), similar resolution, sound on or off for both.
- Use the pack or plan you would actually buy, not the theoretical best rate on a pack you will never finish.
- Divide by keepable seconds after retries, not by theoretical maximum length.
- Ignore free first tests after week one unless you only ever need one clip.
- If video is locked behind a top tier you would not otherwise buy, include that whole fee in the numerator.
When a higher sticker price wins
Heavy daily video on a flat Pro-style plan can beat Coin tiles once your keepable seconds per cycle are high enough that the fee spreads thin. Occasional creators usually pay less overall on transparent per-tile Coins that never expire, even when each second looks pricier on paper. Self-hosting open models such as Wan can drop the marginal cost toward electricity and GPU time, but needs hardware and setup; that path is outside hosted cost-per-second math.
Always re-check the live tile or Gem cost. The arithmetic above is only as good as today’s published numbers.
Safety notes
Only generate fictional adults, or animate yourself or consenting adults. Image-to-video and two-person modes multiply misuse risk; platforms forbid under-18 content. Follow that rule without exception.
