THE SHORT ANSWER
What is an AI video face swap?
An AI video face swap puts a different person into a clip you already filmed. In Aisma, you upload a 2–60 second video with photos of the new person and write one line saying who they replace. The new face and hair come from your photos; the gestures, setting, camera move and original audio stay as filmed.
Works with clips you already shot: 2–60 seconds, up to 500 MB, MP4 or MOV.
Vertical, square and horizontal clips all work.
Every swap on this page used two photos of the new person; you can add up to 10 (JPEG, PNG or WebP).
720p or 1080p, with the price in credits shown before you generate.

MORE FACE SWAPS
Another person. Same performance.
A cook at the stove and a man on a seaside terrace. The stir, the spoon, the apron and the linen jacket stayed as they were in the original.

Another cook. Same recipe.
Bald, bearded, same stir.swap the cook for the man in the photos
The first runs for the veteran and the rookie came back with the blue T-shirt in another color. Once the request named it exactly, “bright royal-blue crew-neck T-shirt,” both reruns kept it. The newcomer’s photos showed a charcoal T-shirt, and she wears it in her first run; we kept that take.
The cook
Previous version · September 13, 2026 · 10-second clip · 1080p · 2 runs, 2 kept
Both takes came from the first run. The apron and the stir stayed in each; the shirt wasn’t named, and in the silver-bob take it became the charcoal T-shirt from her photos.
The terrace
Previous version · September 8, 2026 · 10-second clip · 1080p · 1 run
One run. The request asked to keep his clothing, and the linen jacket stayed, though his photos show a black T-shirt.

HOW IT WORKS
How to swap a face in a video.
Choose
your video
MP4 or MOV, 2–60 seconds, up to 500 MB. Your original framing is kept.
Add two
portraits
Two photos of the same person, then one line such as “replace the man with the person from the photos.” Add a second line for clothes that must stay.
Review credits,
then generate
Pick 720p or 1080p. Aisma shows the credits first, and the finished edit arrives in your private Library.
The hair too. In every swap on this page the face, hair, skin tone and facial hair came from the portraits, down to the veteran’s gray mustache. Gestures, head turns and the cook’s stir stay as performed.
Will the clothes in my video stay the same?
Yes, when your request names them precisely. Clothes in your photos can come along with the face: the newcomer’s request asked to keep the blue T-shirt, and she still wears the charcoal one from her photos. Naming the shirt exactly, “bright royal-blue crew-neck T-shirt,” kept it blue for the veteran and the rookie. To keep the person and change just the outfit, use the clothes changer.
Will the voice change too?
No. Aisma keeps the audio you recorded, so the new person talks with the original voice. A new voice to match the face is on our roadmap; if your project needs one, write to support@aisma.ai and tell us what you’re making.
How do I swap a face in a video?
Upload the clip with two photos of the new person and write the request, for example “Replace the man with the person in Photos 1 and 2. Keep his royal-blue crew-neck T-shirt.” Choose 720p or 1080p, check the credits and press Generate. It works in the browser and in the iPhone and Android apps. More wording tips are on the edit with a prompt page.
What kind of clips get the best results?
Clips where the face is easy to see. The kitchen take at the top of this page is a good model: one continuous 10-second shot, a man talking to the camera from about arm’s length, his face in view the whole time. Start there before you try a crowd or a face that turns away.
How long can a face swap video be?
Any clip of 2–60 seconds and up to 500 MB, as an MP4 or MOV file. The swap comes back at the same length and framing, in 720p or 1080p. For a longer video, swap it in parts of up to 60 seconds; longer clips are on our roadmap.
Can I swap more than one face in a clip?
Yes. Add photos for each person and say who goes where, for example “Replace the man on the left with Photos 1 and 2, and the woman with Photos 3 and 4.” On the web, Aisma may ask which photo goes with whom before it renders. One person per request gives the most predictable result. To take someone out of the shot instead, see how to remove people from a video.
How long does a face swap take?
Minutes. A longer clip takes longer, and the task page shows progress until the swap appears in your Library.
How much does a video face swap cost?
Aisma is paid with credits. The price depends on the clip’s length and the quality you pick, and Aisma shows the exact number before you press Generate; a part that fails or doesn’t pass the safety check isn’t charged. On the web, a new account can prepare its first three edits before buying credits. Rendering uses credits. Credit packs and weekly plans are on the pricing page.
Whose photos can I use for a face swap?
Your own, or photos of someone who agreed to it. Aisma is for footage and photos you own or have permission to use, so swaps with a celebrity’s or a stranger’s face, or ones meant to fool people, aren’t something Aisma offers.
Who can see my photos and the finished video?
Your clip, your photos and the result are private to your account and open through short-lived links. Without an active weekly plan, a finished edit stays in your Library for 72 hours, so save it to your device; you can delete any task at any time. The examples on this page were made separately for public use.
Are these real results?
Yes. The kitchen talk, the cook at the stove and the man on the terrace are real Aisma edits of the takes shown with them, and Full Aisma edit plays each swap whole. Examples marked Previous version were recorded with a previous version of Aisma. Before → After views show the original and the edit at the same moment of the clip, never cropped, sped up or retouched. Your result depends on your clip and request.
