AI character swap on Genjutsu AI is for anyone with a clip: upload an MP4 or MOV, pick 5 to 30 seconds and add a photo of a person, an anime or 3D character, or a mascot. A swap costs from 39 credits (about $1.45); new accounts get 3 free credits, not enough for one on their own. The MP4 comes back in your clip’s shape at 480p to 1080p with its original sound, watermarked until your first purchase.
How an AI character swap works here
- 01
Upload the video and pick the seconds
Upload my video is already selected: add an MP4 or MOV between 5 seconds and 5 minutes, up to 50 MB, then slide to the 5 to 30 seconds you want (up to 15 on MiniMax H3).
- 02
Add the character photo and say who it replaces
Keep the change type on Character, add a photo of the new person or character (up to 9 images, 10 MB each) and edit the instruction so it names who in the clip each image replaces, for example “the man in the black hoodie”.
- 03
Pick the model and generate
Seedance 2.5 edits the clip itself; MiniMax H3 redraws it with your clip as the reference. The button shows the exact credits first, and the finished MP4 carries the selected seconds’ original sound.
AI character swap examples: original clip and swap
Each pair below shows an original clip on the left and its character swap on the right: one person, a couple and a trio, each replaced by new characters while the setting and the framing match. The clips are silent, landscape and 13 to 14 seconds long.
Original clip
Character swap
A woman in headphones talking to a selfie camera on a forest road is swapped for an aviator in a leather flying helmet, goggles and a sheepskin collar. In the swapped clip the head turns, the forest and the framing match the original. 14 s · landscape · no sound.
Original clip
Character swap
A ballroom couple practising in a mirrored studio is swapped for two flamingo characters, one in a white shirt and one in a coral gown. In the swapped clip the hold, the turns and the studio match the original. 14 s · landscape · no sound.
Original clip
Character swap
Three dancers under stone arches are swapped for two toy soldiers and a ballerina doll. In the swapped clip the routine, the three positions and the arches match the original. 13 s · landscape · no sound.
Is AI character swap the same as a face swap?
AI character swap is not the same as a face swap: a face swap pastes a new face onto the person and leaves their hair, body and clothes, while a character swap replaces the whole person (face, hair, body and outfit) from your photo. A body swap sits between the two, and motion transfer moves the clip’s movement onto a character in a newly drawn scene.
| Method | What changes | What comes from the original clip | Typical input |
|---|---|---|---|
| Face swap | The face only | Hair, body, clothes, movement, background, sound | Video + face photo |
| Body swap | Body and outfit, often the face too | Pose, movement, background | Video + full-body photo |
| Character swap (this page) | The whole person: face, hair, body and clothes, from your photo or drawing | Movement, timing, camera and background are the guide; the sound is the original recording | Video + photo or drawing of the character |
| Motion transfer | Everything: the character performs the clip’s moves in a new scene | Movement and timing only | Video + character image |
Pick a character swap when the new person should look different from head to toe, such as yourself as a cartoon mascot or a friend as an anime character; pick a face swap when only the face should change. The “AI character swap” trend videos people post to TikTok and Reels are not one meme with one sound: they reuse any dance, rap or movie clip with a new character, so you start from whichever clip you like. For a built-in clip that only needs your photo, see motion transfer.
Swapping two or more characters in one video
AI character swap here can take one photo per new character, up to 9, but the built-in wording only asks the model to replace the main person with the people in your images: who each image goes on, and who stays as filmed, comes from your instruction. Name each person by something only they have, such as their side of the frame or their clothes at the start. Results vary with the model, so check where two people cross or hug. Instructions you can copy and adapt:
Replace the person in the red jacket in @Video 1 with the character in @Image 1, including face, hair, body and outfit. Keep the movement, expressions, camera, lighting and background exactly as in the clip.
Replace the two dancers in @Video 1. The dancer on the left in the black top becomes the person in @Image 1; the dancer on the right in the white dress becomes the person in @Image 2. Keep their moves, positions and the camera unchanged, and never swap the two identities.
Replace the man dancing in @Video 1 with the anime character in @Image 1, keeping the character’s drawn style, colours and outfit. Keep the dance, timing, the street and the other people unchanged.
Two-person built-in clips have their own casting, explained on the duo swap page.
Is this AI character swap free to use?
AI character swap on Genjutsu AI is not free to generate: the cheapest swap is 39 credits (about $1.45), and the 3 sign-up credits do not cover one on their own. Uploading your clip, trimming it, adding photos and seeing the price cost nothing, and you need an account only to generate. Swaps from accounts without a purchase carry a moving genjutsu-ai.app watermark; any purchase unlocks clean downloads, including earlier videos.
| Question | What happens here |
|---|---|
| Price per swap | 39 to 928 credits (about $1.45 to $34.50 at the lowest credit price), set by the model, the resolution and the seconds you select. A 10-second swap on Seedance 2.5 at 480p is 78 credits (about $2.90). |
| Free credits | 3 sign-up credits, valid for 7 days. Not enough for a swap on their own: the cheapest is 39 credits. Uploading, trimming and seeing the price cost nothing. |
| Smallest purchase | The $5 Trial pack (one-time) has 24 credits, not enough for one swap. The smallest one-time pack that covers one on its own is $12 for 220 credits. The cheapest start from zero is the $9 Starter plan, a monthly subscription with 240 credits a month. |
| Watermark | Swaps from accounts without a purchase carry a moving site watermark. Any purchase unlocks clean downloads of earlier and later videos. |
| Failed or rejected | If the model fails, or its review turns down a photo or the clip, the credits go back automatically; an upload stopped by the safety check is never charged. If the model has delivered and only adding the sound back or exporting fails, the credits are kept and support finishes the video. A finished swap is not refunded. |
AI character swap pricing and credits
An AI character swap here costs 39 to 928 credits, about $1.45 to $34.50 at the lowest credit price; the model, the resolution and the seconds you select set the price. A 10-second swap is 78 credits on Seedance 2.5 at 480p (about $2.90), 175 at 720p, 310 at 1080p, and 77 on MiniMax H3 at 720p. The smallest one-time pack that covers one swap is $12 for 220 credits, or the $9 Starter plan (a monthly subscription) gives 240 credits a month.
| Model · resolution | 5s | 10s | 15s | 30s |
|---|---|---|---|---|
| Seedance 2.5 · 480p | 39 | 78 | 117 | 233 |
| Seedance 2.5 · 720p | 88 | 175 | 262 | 523 |
| Seedance 2.5 · 1080p | 155 | 310 | 464 | 928 |
| MiniMax H3 · 720p | 39 | 77 | 116 | — |
| MiniMax H3 · 1080p | 62 | 123 | 185 | — |
Both models bill for the seconds of your clip they read and again for the seconds they output, which is why a swap costs more per second than a text-to-video clip. If the model fails or its review turns down an input, the credits come back automatically; if the model has delivered and only our sound and export step fails, the credits are kept and support finishes the video. More packs and plans are on the pricing page.

Do you need an AI character swap app?
AI character swap on Genjutsu AI needs no app and no download: the editor runs in a phone or desktop browser. On an iPhone or Android phone, open this page, tap Upload my video and pick the clip from your gallery; a long 4K phone video may be over the 50 MB limit, so trim or export it smaller first, and download the finished MP4 to post it.
“AI character swap mod APK” downloads are not official apps of any of these tools and can carry malware; use an app store or a website instead.
What AI character swap does badly
AI character swap works best on a clip with one clear, well-lit person and steady framing; it does worst where the model has to invent what it cannot see, such as a face behind a hand or the back of a costume. The prompt asks the model to follow the clip; results vary with the model, the clip and the photo. These are the usual problem spots, with what helps:
| What you may see | Why | What helps |
|---|---|---|
| The new face changes during a head turn or a spin | The face is hidden or side-on for a few frames and has to be redrawn | A sharp front photo plus a three-quarter view; a slower or shorter section |
| Arms or legs bend oddly in fast moves | Motion blur hides the limbs the model has to follow | A clip with less blur, or the calmer seconds of it |
| Two new characters swap or blend | The instruction did not tell them apart clearly | Name each by side and clothes at the start of the clip; different-looking photos |
| Lips do not quite match the voice | The model redraws the mouth; the sound is the original recording | Seedance 2.5, which edits the clip itself, or a wider shot |
| Seedance 2.5 refuses before it starts | Its review turned down a photo or the clip; the credits come back | A clearer photo of an adult, or MiniMax H3 |
It does not render more than 30 seconds in one go, swap characters live on a camera, or write new dialogue or music.
