Choose an Unobstructed Face
Use an evenly lit portrait where the eyes, nose and mouth are easy to see. Heavy filters, hair across the face and strong shadows make the identity harder to judge.
AI Face Swap Video
Bring a clear portrait and a reference performance to create a video with a different on-screen identity. Tell the Pexo AI video agent which person and scene you mean, then review the face as the performance moves.
Portrait + reference video
Add the Face and the Performance
Use a portrait you have permission to use and identify the person in the reference clip.
Use your own face or get the person's permission. Only use footage you have the right to edit.
Two inputs, two different jobs
The face sets identity. The clip sets the action.

Choose the face before directing the change
The portrait supplies identity; the performance supplies movement and scene context. Give the Agent both, and name the intended subject.
01
Use authorized material
A stock-photo license is not consent to impersonate the person shown.
02
Review moving details
Check expressions, head turns and face edges in the actual result.
Face and footage
Start with the Right Face and Performance
An AI face swap video uses a portrait to change the apparent identity of a person in a moving scene. The portrait answers who should appear; the reference performance shows the action you want to follow.
In Pexo, make both parts explicit. Name the performer and the moment you want to change, especially if other people enter the shot. A face request is not a request to replace the person's clothing, body or surroundings, and the result still needs a visual check.
Point to the Right Person
Identify the performer and relevant scene or time range. A vague instruction becomes harder to follow when the shot contains several people or quick cuts.
Say What Should Stay Familiar
Explain which action and scene details matter to you. Review the result rather than assuming that every surrounding detail will remain identical.
How it works
Create a Face Swap Video in 3 Steps
Connect the portrait to the performance, define the change, and check the result beyond a single flattering frame.
Add the Portrait and Reference Clip
Provide a clear portrait and the performance you want to follow. Start with a short, easy-to-identify moment so you can judge the identity change without unrelated scenes getting in the way.
Identify the Performer and Scene
Tell the Agent which person should use the portrait reference. Describe the action and any details that are important to retain; ask for a face change separately from a new character or costume.
Review the Face Through the Motion
Watch the head turns, blinks and expressions, not just the opening frame. If the resemblance changes or an edge looks wrong, point to that exact moment when requesting a revision.
What to look for
Keep the Face Change Believable
A convincing result needs more than a recognizable still. These are the details to describe and inspect as the scene plays.
A Clear Identity Reference
Choose one portrait that represents the appearance you want. If the reference is heavily retouched, it becomes harder to tell whether a result follows the person or the filter.
Original identityRecast concept
A Specific Performer
Make the intended subject unambiguous. When two people share the frame, describe their position or clothing and say which person should be changed.

Expressions and Head Turns
Check whether the face remains recognizable as its angle and expression change. Pay attention to the eyes, mouth, jawline and moments when a hand crosses the face.

Changes You Can Point To
Request a correction to a particular shot or moment rather than saying only that the face looks wrong. Concrete feedback gives the next revision a clearer target.
Questions answered
Face Swap Video Questions
What kind of portrait should I use?
Use a sharp, evenly lit portrait with a clearly visible face. Avoid strong beauty filters, sunglasses and obstructions. Choose a photo that matches the appearance you actually want in the video.
How do I identify the person to replace?
Describe the person's position or clothing and name the scene or time range. If several people appear, make the intended subject explicit rather than asking to change a face somewhere in the clip.
Will changing the face also change the voice?
A face change and a voice change are separate requests. Do not assume the portrait will change speech or audio; tell the Agent if you also need a different spoken performance.
Will the rest of the video stay exactly the same?
Do not assume pixel-for-pixel preservation. Explain which parts of the scene matter, then compare the result with the reference. Fast movement, head turns and partial obstructions deserve particular attention.
Can I use someone else's face or video?
Get permission from the person and make sure you have the right to edit the footage. Do not use a face swap to impersonate someone deceptively, claim a false endorsement, or create humiliating or harmful content.
