Why teams pick Fliki for character swap
Swap the whole person, keep the whole shot
A face swap changes a face. A character swap replaces the body, clothes and look of the person on screen while the original performance stays. Fliki runs it on P-Video Replace and hands the result straight to a video editor.
Full body, not just a face
P-Video Replace swaps the entire person: face, hair, body shape, outfit and skin tone. Your new character inherits every step, turn and hand gesture from the original take.
The shot stays untouched
Camera move, framing, lighting, background and timing come from your source video. Nothing gets regenerated around the person, so the clip still cuts cleanly with the rest of your edit.
One photo is enough
Upload a single clear photo of the character. A real person, a 3D mascot, a cartoon or an AI-generated hero all work. No training set, no 20-image upload, no waiting for a custom model.
Reshoot without a reshoot
Keep the take you already love and change who is in it. Swapping a spokesperson for a regional market takes about a minute, against a day of crew, studio and talent fees for a new shoot.
Voice it in 80+ languages
Send the swapped clip to the Fliki editor and give the new character a voice from 2,000+ voices in 80+ languages with AI voiceover, or clone your own. The character speaks whatever market you are shipping to.
Lip sync the new character
When the new script differs from the original line, run AI lip sync on the swapped clip so the mouth matches the new audio. Character swap and lip sync chain together in one project.
Captions and b-roll in place
Add animated captions, cutaway b-roll, music and your brand kit to the swapped clip without exporting to another tool. The result is a finished ad or post, not a raw clip to fix elsewhere.
Saved to your drive
Every result lands in your Fliki drive next to the source. Run three characters on the same take, compare them side by side, and keep the one your team picks.
Commercial use on paid plans
Character swap is included in paid plans and billed in credits per run. Results are watermark-free and cleared for ads, client work and paid social, as long as you have consent from everyone shown.
How it works
How to swap a character in a video in 4 steps
Two uploads and one click. The performance comes from your video, the look comes from your photo.
Step 1
Upload the video
Pick a clip where one person is clearly visible. Steady framing and a full view of the body give the cleanest swap.
Step 2
Add the character photo
Upload one well-lit photo of the new character, ideally front-facing and full length so the outfit carries over.
Step 3
Run the swap
P-Video Replace rebuilds the person frame by frame while the motion, camera and background stay. Results arrive in about a minute.
Step 4
Finish in the editor
Open the result in Fliki to add a new voice, lip sync, captions, music and b-roll, then export in any aspect ratio.
Use cases for AI character swap
One take. Any character in it.
Ad variants, regional spokespeople, brand mascots and film previs all start from footage you already have.
Spokesperson localisation
Give each market a local spokesperson
Shoot one spokesperson video, then swap in a presenter who fits each region and voice them in the local language. One master take becomes a campaign for ten countries.
Brand mascots
Put your mascot into live-action footage
Film a person doing the moves, then replace them with your 3D or illustrated mascot. The mascot walks, waves and reacts with real human timing for social posts and launches.
Film previs
Preview casting and costume before the shoot
Run a rehearsal take through different actors or costume designs to see how a scene reads before you book talent. Directors and producers decide on footage, not mood boards.
