Search for "ai face swap video 3.0" and the match for the exact phrase is a page on face-swap.ai that uses it as its headline. It reads like a release announcement for a new model: version number, accuracy percentages, quotes from happy creators. Check each element, though, and every one turns out to be something else. The version belongs to a marketing page, the percentages come from tests nobody can inspect, and the button that offers to start swapping opens a different company's website.
This article documents what we found on that page on July 31, 2026, then covers the part the page skips: what a video face swap actually costs when a platform posts its price calculation in the open.

Key Takeaways
- "AI Face Swap Video 3.0" is the branding on one face-swap.ai landing page. The accuracy figures on it (up to 97% tracking, up to 96% frontal alignment, roughly 92% expression retention) are labeled "internal tests" with no method, test set, or sample size published.
- Every start button we checked on five face-swap.ai tool pages links to deepswap.ai, a separate subscription service, with referral tracking parameters attached. The site's own Terms of Service never mention DeepSwap.
- The page is aimed at TikTok creators, yet the site greets visitors with an 18+ age gate, and its navigation carries a full set of NSFW generator pages.
- On Atlas Cloud, the equivalent job runs as atlascloud/face-swap-video with the price shown before you click: $0.09 per run plus $0.20 per second at 720P or $0.24 per second at 1080P. Our 5.6-second 1080P test billed $1.438615.
What Is AI Face Swap Video 3.0? A Landing Page, Not a Model
The page itself is face-swap.ai's video tool page, and its opening line calls 3.0 "the latest generation of our video face swap pipeline—built for crisp, consistent results on short-form platforms like TikTok, and trusted by creators worldwide." Nothing on the page gives a release date, a changelog, or any record of what changed from the previous version. The FAQ describes the upgrade in general terms: stronger detection and tracking, better alignment, better expression retention.
Captured with a fresh browser session, July 31, 2026.
Loading the page in a clean browser produces the screenshot above: the first interaction is an age gate, "You Must Be 18+ to enter this website." That gate makes more sense once you open the site's navigation, which lists NSFW Image to Video, NSFW Text to Video, NSFW Text to Image, and an NSFW AI Tools hub alongside the face swap pages. The homepage, meanwhile, describes the whole operation as "professional-grade AI technology, zero restrictions, completely free" and cites 47K+ creators worldwide with a 96.7% satisfaction rate. Those two numbers appear without any source, and the free claim contradicts the video page's own text, which says you should "start free, then upgrade when you need longer clips or premium models."
AI Face Swap Video 3.0 Accuracy Claims: Big Percentages, No Method
The percentages are the most quotable part of the page, so they deserve exact quoting. Face tracking reaches "up to 97% accuracy for stable tracking in demanding footage." Frontal alignment is "up to 96% (from 93%)"; profile alignment "up to 86% (from 73%)." Expression retention lands at "roughly 92%."
All values quoted from face-swap.ai/en/video-face-swap, July 31, 2026.
Each figure traces back to the same two words: "internal tests." The page names no benchmark, no test footage, no sample size, and no measurement protocol, so there is nothing for a third party to reproduce. Academic face swap work is usually scored on public datasets with published metrics, which is what lets a percentage be checked. A percentage without a method can only be repeated, not evaluated.
The two testimonials follow the same pattern. "Riley Chen · Short-form content lead" praises the 3.0 tracking; "Alex V. · Indie brand marketer" says a browser workflow beat a self-hosted FaceFusion stack. Neither quote links to a company, a channel, or a post, so neither can be verified. The FAQ also states, credibly, that the site is not affiliated with FaceFusion, the self-hosted face swap project those searches reference.
How to Face Swap a Video on Atlas Cloud, With the Price on the Button
A version number you can't inspect is one way to sell a face swap. A price you can read before you click is another. Atlas Cloud, the platform that serves 400+ models through one API, runs a native atlascloud/face-swap-video endpoint in its tools lineup, next to a companion image endpoint, image and video upscalers, and a photo restoration tool. The video endpoint replaces the person in a clip while motion, timing, camera movement, and background stay as shot, at a catalog rate listed from $0.20 per second.
We wanted a concrete anchor for this article, so we ran the job ourselves rather than describe it from the documentation. Two paths lead to the same result, and both bill identically.
Method 1: Run a Video Face Swap in the Playground
The model playground needs no code. Log in and fill two slots. Source Face takes one clear, front-facing photo of the identity you are placing into the footage; the slot accepts a single file and marks itself full at 1/1. Target Video takes the clip whose person gets replaced, MP4 or MOV, 2 to 10 seconds, up to 100MB, uploaded directly or added by link. Output Resolution offers 720P or 1080P, with 1080P as the default. The run button then prints the calculated price for that exact combination.
Our run, July 31, 2026. The interface notes that $10 covers roughly six runs of this size.
Our test: a smiling portrait as the source face, a 5.6-second fantasy archer clip as the target, 1080P output. The button quoted $1.438615, the job completed, and the side-by-side comparison we saved from it measures 1920×1080 at 30fps. One detail worth knowing before you spend money: the model page describes the operation as replacing the person, and in our run that was literal. Hair and overall identity followed the source photo, not just the face region. The page also carries a consent notice worth repeating, since it applies to every tool in this article: only upload media you have the right to use, and get consent from the people shown.
Method 2: Script It Through the Face Swap Video API
The same endpoint takes scripted traffic, which is how a batch of clips runs without anyone sitting in a browser tab.
Step 1: Get your API key. Create one in the Atlas Cloud console dashboard and copy it.
Step 2: Check the API docs for authentication and the shared video endpoint parameters.
Step 3: Send the request. Video face swap goes through the same generateVideo endpoint as the platform's video generation models:
Bash1curl -X POST https://api.atlascloud.ai/api/v1/model/generateVideo \ 2 -H "Authorization: Bearer $ATLASCLOUD_API_KEY" \ 3 -H "Content-Type: application/json" \ 4 -d '{ 5 "model": "atlascloud/face-swap-video", 6 "image": "https://your-cdn.com/source-face.jpg", 7 "video": "https://your-cdn.com/target-clip.mp4", 8 "resolution": "1080P" 9 }'
The payload is deliberately small: image is the source face, video is the target clip, and resolution mirrors the playground menu. There is no prompt field, no seed, no style options, so there is also nothing to tune when a result disappoints beyond supplying better inputs. Generation is asynchronous. The response returns a prediction ID, which you poll until the status reads completed:
Bash1curl https://api.atlascloud.ai/api/v1/model/prediction/<prediction_id> \ 2 -H "Authorization: Bearer $ATLASCLOUD_API_KEY"
The finished clip comes back as a URL in the outputs array. Photo jobs use the companion atlascloud/face-swap-image model with the same key and the same polling loop, so a pipeline that swaps thumbnails today extends to full clips by switching the endpoint to generateVideo, the model string, and the target field.
Where face-swap.ai's Video Face Swap Button Really Goes: DeepSwap
Back on face-swap.ai, we read the link target behind "Start in your browser." It does not open a workspace on face-swap.ai. It points to deepswap.ai, with utm_source=face-swapAI and a campaign ID attached. We then pulled the HTML of four more tool pages on the site. Same destination every time, each page with its own campaign tag.
Link targets read from each page's HTML, July 31, 2026.
To be precise about what this does and does not prove: face-swap.ai operates its own account system, and a sign-in dialog with email and Google options opens on the page, so we cannot say the site runs no tools of its own. What we can say is that on all five pages we checked, the button a visitor actually presses to start swapping leads to DeepSwap, and that face-swap.ai's Terms of Service, effective June 2024 and administered from Australia, make no mention of DeepSwap at all.
That detour has a price structure of its own. DeepSwap's pricing page bills video face swap at 1 credit per 15 seconds, its Pro tier lists 20 credits per month, and face swap tops out at 30 minutes of video. Read face-swap.ai's FAQ again with that in mind: it describes a "typical segment" of about 15 seconds. The landing page's segment length happens to equal the destination's billing unit.
Video Face Swap Cost: Per-Second Pricing vs Credit Subscriptions
Subscriptions make per-clip costs hard to pin down, since credits arrive monthly whether you swap or not. Per-second billing is easier to reason about, and this one we could verify. Atlas Cloud's price calculator returned $1.09 at 720P and $1.29 at 1080P for a 5-second clip, $1.29 and $1.53 for a 6-second clip. Those points fit one formula exactly: a $0.09 base per run, plus $0.20 per second at 720P or $0.24 per second at 1080P. The run from Method 1 above lands on the same line. No discount was active on this model when we checked.
Prices from the model page calculator and one completed run, July 31, 2026.
Two practical notes follow from the numbers. First, a single run can never cost more than $2.49, the price of the 10-second maximum at 1080P, and that ceiling drops to $2.09 at 720P, a resolution short-form platforms compress toward anyway. Second, if the face only needs to change in a thumbnail or a poster frame rather than the full clip, the platform's separate image endpoint starts at $0.09 per photo, which is the cost of the video model's base fee alone.
Getting a Clean AI Video Face Swap: Source Face and Clip Rules
Here is the part both vendors quietly agree on. Face-swap.ai's FAQ advises that "clear, frontal faces still give the cleanest results," and the Atlas model page asks for a clear, front-facing photo as the source. Whatever pipeline generation is doing the work, the swap succeeds or fails on the same inputs: a sharp frontal source face, and a target clip where the head is not obscured by motion blur.
Frames sampled at roughly 0, 2.7, and 5.2 seconds from our July 31, 2026 run.
The strip above is our 5.6-second run sampled at three points. Identity stays put across the draw of the bow, which is the property face-swap.ai's tracking percentages are trying to describe, except here you can look at the frames instead of trusting a number. The clip limits differ more than the advice does: the Atlas endpoint takes 2 to 10 seconds per run, while face-swap.ai's FAQ describes chaining 15-second segments for longer stories, on top of whatever DeepSwap's subscription allows. For a longer edit, cutting the video at scene boundaries and swapping only the shots where the face appears keeps both the cost and the artifacts down.
And the consent line is not boilerplate. Tools that replace a person in footage are exactly the category regulators and platforms tightened rules around through 2025 and 2026. Swapping your own face, a consenting friend's, or a fully synthetic character keeps you inside every policy quoted in this article; swapping a stranger's does not.
Frequently Asked Questions
Is AI Face Swap Video 3.0 free?
The landing page says you can start free and upgrade for longer clips and premium models, while the same site's homepage says everything is completely free. The workspace its buttons open is DeepSwap, which sells subscriptions with monthly credits, so plan for the paid path if you need more than a trial.
Who actually processes a video started from face-swap.ai?
Every start button we checked on five of the site's tool pages links to deepswap.ai with referral tracking parameters. The site has its own account dialog, but we found no page where a video swap runs on face-swap.ai itself, and its Terms of Service do not describe the DeepSwap relationship.
Is "3.0" a standard version of some well-known face swap model?
No. The 3.0 label is face-swap.ai's own branding for its landing page, and the page never names the model working underneath. Version numbers in this space are vendor marketing, so a "3.0" by itself tells you nothing about whose technology is running.
How much does a video face swap cost on Atlas Cloud?
$0.09 per run plus $0.20 per second at 720P or $0.24 per second at 1080P, verified against the model page's calculator and a real billed run on July 31, 2026. A 5-second 1080P swap is $1.29; the 10-second maximum is $2.49.
What input limits does the Atlas endpoint have?
One source face photo, one target video in MP4 or MOV between 2 and 10 seconds and under 100MB, output at 720P or 1080P. The API is asynchronous: submit the job, then poll the prediction until the output URL is ready.
Conclusion
Every headline element of "AI Face Swap Video 3.0" reads differently once checked against its own page. The version number has no documented release behind it, the accuracy figures cite tests nobody outside the company can inspect, the testimonials offer nothing to verify them against, and the start button opens a different company's product with tracking parameters attached. None of that makes the page a scam; DeepSwap is a real service and the swaps it sells are real. It does make the page an advertisement formatted like a product announcement, and anyone comparing tools should know which of the two they are reading.
The test worth applying to any face swap tool is the one this page cannot pass: can you check the claims yourself before spending anything? On Atlas Cloud each piece is checkable. The input limits are printed in the schema, the price calculator answers before you run, and our 5.6-second test billed exactly what the button quoted. A swap that costs $1.44 and shows its arithmetic beats one that costs an unknown fraction of a subscription, whatever version number it carries. The consent requirement applies on every route: swap faces you have permission to use, and no other kind.
