How to Replace Person in Video with AI
Four steps to replace person in video, with no editing software and no green screen.
- 01
Add a portrait photo
Upload a clear photo of the person who should appear, one person per picture. To replace person in video with photos of two or more people, add one photo each, in casting order.
- 02
Pick a template or upload a video
Choose one of 24 built-in clips, or upload your own MP4 or MOV of up to 5 minutes to swap characters in any video. Drag the window to the 5, 10, 15 or 30 second part you want.
- 03
Choose a model and resolution
MiniMax H3 is the default. Switch to Seedance 2.5 for the closest copy of the source motion, or Seedance 2.0 for a lower price. The button shows the exact credits.
- 04
Generate and download
We cut your window, replace person in video with the people in your photos and put the original sound back. Download the MP4, or run it again with another photo.
Replace Person in Video vs Face Swap and Character Swap
A face swap video pastes a new face onto the old head. When you replace person in video here, the whole person changes: a tall person stays tall, and a new haircut or outfit shows in every frame. Character swap AI video tools and AI body swap video apps aim at the same result; what differs is how much of the source they keep.
What comes from your photo
- Face, hair and skin tone
- Body type and build
- Clothes and shoes the photo shows
- Glasses, tattoos and other visible details
Want a new face on the original body and clothes? That is a face swap, a different job. This tool is built to replace person in video with another person; anyone without a photo stays as they were.
Template Clips to Replace Person in Video
No clip of your own? Replace person in video templates are ready to use: single-person clips need one photo, duo clips take two. These are input clips, not results.
24 clips in the picker, from selfie talks and street dances to runway walks and duo scenes.
MiniMax H3 vs Seedance to Replace Person in Video
Three video character replacement AI models can replace person in video here. They share the same upload, clip window and casting, and differ in how they treat your source.
| Model | How it works | Lengths | Output | Best for |
|---|---|---|---|---|
| MiniMax H3 | Rebuilds the shot, using your clip as the motion reference | 5, 10, 15 s | 720p, 1080p (from native 768P / 2K) | The default: steady identity and clean faces at a mid price |
| Seedance 2.5 | Edits your clip directly | 5, 10, 15, 30 s | 480p, 720p, 1080p | Closest match to the source motion and framing; the only model with 30 s |
| Seedance 2.0 | Rebuilds the shot, using your clip as the motion reference | 5, 10, 15 s | 480p, 720p, 1080p | Lowest price, with looser timing and likeness |
Seedance 2.5 first sends the selected clip and your portraits through the provider’s face review. If anything is rejected, the job stops and every credit comes back.

What People Use Replace Person in Video For
Put yourself in a trend. Replace person in video clips everyone is posting with yourself, no dance lessons needed.
Swap friends into a duo clip. Replace someone in a video with someone else from your group: two photos, two people, and each keeps their own face through every cut.
Recast an ad or product video. Film once, then swap person in video for different presenters or markets.
Change music video characters into another person. Make a fan edit where a friend takes the lead, on footage you have the rights to.
Bring a mascot or character to life. Illustrated figures and 3D renders work when the photo shows them clearly.
Preview a casting choice. Change the person in a video with AI to see how someone else would look in a scene before a reshoot.
Tips to Replace Person in Video Cleanly
- One person per photo. Crop anyone else out before uploading.
- Show the outfit. A waist-up or full-body photo tells the model what they wear; a tight face crop leaves clothes to chance.
- Face the camera. A sharp, front-facing photo in even light matters most for close-ups.
- Pick a clean window. People fully in frame, few cuts, no crowd. Busy scenes make it harder to replace person in video cleanly.
- Keep casting notes short. “Photo 2 replaces the woman on the right” beats a paragraph.
- Run it twice. Each run differs a little; keep the one where hands and faces look right.

Replace Person in Video FAQ
Is this just a face swap?
No. A face swap video only changes the face. To replace person in video, the model takes the face, hair, skin tone, build and clothes from your photo and keeps them from the first frame to the last. The motion, camera and background come from the video.
Can I replace more than one person in a video?
Yes. Add up to four photos, one per person. Photo 1 replaces the most prominent person, Photo 2 the next, and anyone without a photo stays as they are. Duo templates already know who is who, so Photo 1 and Photo 2 go to the right performers.
How long can the video be?
Upload a clip of 5 seconds to 5 minutes and pick the window to use. The output is 5, 10 or 15 seconds on MiniMax H3 and Seedance 2.0, and up to 30 seconds on Seedance 2.5. To replace person in video for a longer piece, run several windows and join them in an editor.
Does it keep the original sound?
Yes. When you replace person in video here, the new video is generated silent and the original audio of the window you picked goes back underneath, so the song or voices stay in sync. A silent clip gives a silent result.
Can I change the background or the voice too?
This tool keeps the scene and the sound from your clip on purpose. You can describe a small outfit or prop change in the optional note, but a new location or a new voice is a different job for a video editing or voice tool.
Which model should I pick to replace person in video?
Start with MiniMax H3, the default. Choose Seedance 2.5 when the motion and framing must match the source exactly or you need 30 seconds (a Seedance 2.5 character swap edits the clip itself), and Seedance 2.0 when price matters most.
How long does it take?
A replace person in video job usually takes a few minutes: cutting the clip, generating and restoring the sound. Longer windows and the Seedance 2.5 face review take longer. You can close the page; the job keeps running and appears under your recent videos.
Does the new person have to be real?
No. You can replace person in video with illustrated characters, mascots and 3D renders if the photo shows them clearly, one figure per image.
Can I use someone else’s photo?
Only with their permission. Use photos of adults who agreed to be in the video, and never make sexual or misleading content. Inputs the provider flags are refused and the credits are returned.
Do I need an app to replace person in video?
No. It runs in the browser on desktop or phone: upload, generate and download the MP4 on this page.
