THE SHORT ANSWER
What does it mean to replace a person in a video?
Replacing a person in a video swaps someone you filmed for someone else. With Aisma, you bring a 2–60 second clip and photos of the new person and say who they replace. Face and hair come from the photos, the clothes often do too, and the gestures, camera and audio come from your take.
Starts from
A clip you already shot: 2–60 seconds, up to 500 MB, MP4 or MOV
Photos
Two of the new person, front and three-quarter, as in every edit here; up to 10 per edit (JPEG, PNG or WebP, 20 MB each)
Changes
The person: face, hair, skin tone and often the clothes, unless you name the ones that stay
Stays
Gestures, head turns and timing, the setting, the camera move, your framing and your audio
Returns
An MP4, 720p or 1080p, as long as your clip, saved to your private Library
Price
In credits per second of video, shown before you generate
What stays
Gestures, head turns and timing, as performed
The setting, the light and the camera move

Often the clothes too; name the ones that must stay
What you bring
Your clip + photos of the new person + a request saying who they replace
A SECOND SCENE
The apron stayed. The shirt went both ways.
Both cooks came from two portraits each, and the brief asked to keep the apron, the stir and the spoon. Nobody mentioned the shirt: the bald, bearded cook kept the dark olive one, and the woman with the silver bob wears the charcoal T-shirt from her photos.

WHAT COMES FROM WHERE
From your photos, from your clip.
Five people replaced the original in two scenes on this page. Here’s where each part of the shot took its look from, and what happened in those edits.
What a person replacement in Aisma takes from the photos and what it keeps from the clip, with what happened in the five edits on this page
Part of the shot
Comes from
In the edits on this page
Face, hair and skin tone
Your photos
All five faces and hairstyles match their portraits, down to the veteran’s gray mustache and the cook’s silver bob
Clothes
Often your photos; your clip when the request names them exactly
The newcomer and the silver-bob cook wear the T-shirts from their portraits; the named apron stayed, and the named T-shirt stayed blue
Gestures, head turns and timing
Your clip
Each new person makes the original’s hand gestures and stirs the pot at the same moments
Setting, light and camera
Your clip
Both kitchens, the window light and the framing match the originals
Sound comes from your clip as well: Aisma keeps the audio you recorded, so a voice stays the voice you filmed.
To keep the outfit and change the face and hair, name the clothes in your request; the video face swap page has tips for the portraits.
WORD FOR WORD
The briefs we sent, take by take.
The players show each request in short form. These are the briefs behind four of the takes, exactly as we sent them, with what changed and what stayed.
The veteran: the T-shirt named, and it stayed blue.
The brief
Replace the man with the same person shown in Photos 1 and 2. Keep his bright royal-blue crew-neck T-shirt exactly the same colour as in the video. Preserve his hand gestures, head movement, the kitchen, lighting and camera. Keep the new person's appearance consistent throughout.
What changed
The man became a fictional man about 55, the one in the portraits: gray curls, the gray mustache, his face and skin tone. The T-shirt came out a brighter blue, without its chest pocket.
What stayed
A blue crew-neck T-shirt, the hand gestures, the head movement, the kitchen, the light and the camera.
September 28, 2026 · 10-second clip · 720p · second run. The first run asked to “preserve the blue T-shirt,” and the T-shirt changed color.
Replace the man with the woman shown in Photos 1 and 2. Preserve the blue T-shirt, hand gestures, head movement, the kitchen, lighting and camera. Keep the new person's appearance consistent throughout.
What changed
The whole person: a fictional woman about 32, with her own face, long black hair and arms, in the charcoal T-shirt from her portraits, although the brief asked to keep the blue one.
What stayed
The hand gestures, the head movement, the kitchen, the light and the camera.
September 28, 2026 · 10-second clip · 720p · first run, kept as it came out.
The bearded cook: the shirt not named, and it stayed.
The brief
Replace the cook with the same person shown in Photos 1 and 2. Preserve the apron, stirring action, spoon, the kitchen, lighting and camera. Keep the new person's appearance consistent throughout.
What changed
The cook became a fictional bald, bearded man about 45, the one in the portraits: his face, head and beard.
What stayed
The dark olive shirt nobody mentioned (his portraits show a black T-shirt), the beige apron, the stir, the wooden spoon, the glance at the lens, the kitchen and the camera.

The silver-bob cook: the apron named, the shirt not.
The brief
Replace the cook with the woman shown in Photos 1 and 2. Preserve the apron, stirring action, spoon, the kitchen, lighting and camera. Keep the new person's appearance consistent throughout.
What changed
The cook became a fictional woman about 60 with a silver bob, and the shirt nobody mentioned became the charcoal T-shirt from her portraits.

List what they hold and wear on top.
Props and layers belong in the same sentence. Both cooks kept the apron and the wooden spoon, which the brief listed.
Keep the apron, the stir and the wooden spoon.
HOW IT WORKS
How to replace a person in a video.
Choose
your video
MP4 or MOV, 2–60 seconds, up to 500 MB. Your original framing is kept.
Add photos,
say who goes
Two clear photos of the new person, then a request such as “Replace the man in the blue T-shirt with the woman in Photos 1 and 2.” Name anything 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.
Is replacing a person the same as an AI body swap?
It’s the same idea: the person you filmed becomes someone else, and the movement stays. In Aisma you do it on a clip you already shot, with photos of the new person and a request saying who they replace. In the kitchen talk at the top, all three new people gesture on the same beats as the original.
How is it different from a face swap?
In Aisma it’s the same request box, and the difference is what you ask to keep. Name the outfit to keep it, and the face and hair are what change, as with the veteran and the rookie, whose T-shirt stayed blue. Leave it out and the photos can dress the new person too, as they did for the newcomer and the cook with the silver bob. Portrait tips for new faces are on the video face swap page.
Can I keep the clothes from my video?
Yes. Name them exactly in a second sentence. In our kitchen runs, “preserve the blue T-shirt” wasn’t enough: the T-shirt changed color in all three first takes. Describing it as a bright royal-blue crew-neck T-shirt kept it blue in both reruns.
Which photos work best?
Two clear photos of the same person, one from the front and one at three-quarters, sharp and evenly lit, with nobody else in them. Pick photos where they wear what they should wear on screen, since the clothes can carry over. You can attach up to 10 photos per edit (JPEG, PNG or WebP, up to 20 MB each) and point to them by number in the request.
Can I replace two people in the same clip?
Yes. Give each new person their own photos and match them in the request: “the man on the left becomes Photos 1 and 2, the woman on the right becomes Photos 3 and 4.” If the pairing isn’t clear, Aisma can ask on the web before it renders. A single person per clip is the easiest place to start.
Does the voice change too?
No. The picture changes and the soundtrack doesn’t: Aisma keeps your original audio, so whoever appears on screen speaks with the recorded voice. Matching voices are on our roadmap; tell us about your project at support@aisma.ai.
What kind of clips get the best results?
Ones where the person stays in view at a steady distance, face and clothes easy to see. The cook clip here fits: a single 10-second take, waist up at the stove, with one glance at the camera. Try one person like that before a crowd or someone who walks out of the frame.
How long can the video be, and how long does the edit take?
Bring an MP4 or MOV of 2–60 seconds, up to 500 MB, vertical, square or horizontal. The result keeps that length and framing, in 720p or 1080p. An edit takes minutes, more for a longer clip; the task page shows its progress, and the result lands in your Library.
How much does it cost?
Aisma is paid with credits: 8 a second at 720p, 16 at 1080p. The editor shows the exact number before you generate, and a part that fails, or that the automatic safety check turns down, costs nothing. On the web, a new account can prepare its first three edits before buying credits; rendering uses credits. Packs and weekly plans are on the pricing page.
Whose photos can I use?
Your own, or photos of someone who agreed to appear in your video. Aisma is for footage and photos you own or have permission to use. Putting a celebrity or a stranger into a clip, or making one meant to fool people, isn’t something Aisma offers.
Who can see my clip, my photos and the result?
They stay private to your account, and each file opens through a short-lived link. Without an active weekly plan, Aisma keeps a finished edit in your Library for 72 hours, so download it to your device; you can delete any finished task whenever you like. The examples on this page were made separately for public use.
Are these real results?
Yes. All five people here, three in the kitchen talk and two at the stove, are actual Aisma edits of the takes beside them; Full Aisma edit plays any of them 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.
