# AI Costume Changer > An AI costume changer redresses the person in a video as a costume — vampire, astronaut, knight or your own superhero — while their face, moves and setting stay. In Kenerate Genjutsu, pick Change outfit, upload a 2–30 second clip, describe the costume or add a photo of it as @image1, and download an MP4 with no watermark.

Genjutsu's Change outfit instruction keeps the face, identity, hair and skin tone exactly the same and changes only the clothing — perfect for a vampire cape, a pirate coat or a sequined showgirl costume. Masks, full helmets, creature heads and heavy prosthetics change the face itself, so they belong in Replace character, which takes the whole figure from your reference image and keeps only the performance. ### Writing a costume the engine can build Keep it to two or three sentences — prompts can run to 1500 characters, but a focused description beats a long one. A reference image beats both when you have one. - Era or genre: Victorian, 1980s, sci-fi, fantasy. - Main garments, top to bottom. - Materials and finish: velvet, worn leather, polished steel. - Two or three colours, named precisely. - Worn accessories: belt, crown, gauntlets, cape. - Condition: brand new, battle-worn, tattered. ### Planning a costume reveal Shoot the source with the reveal in mind: a spin, a jump, a coat flick or a hand passing across the camera all make natural cut points. Keep the original audio on so the music stays in sync. Then run several costumes from the same take and edit them into a sequence — one performance, many looks, without a costume budget. ### Group costumes and couples Change outfit targets the main person in the shot. For a couple or group theme, start with the most prominent person, then upload the result and run again for the next person, naming them by position — "the man on the right". Each pass is a new generation, so check faces and hands in the compare view every time. ## FAQ Q: Can AI change my costume in a video? A: Yes. Upload the clip to Genjutsu, choose Change outfit and describe the costume or add a photo of it. The engine is told to change only the clothing and keep your face, hair, body shape, motion, expressions and lip movement, so the costume moves with you through the whole clip instead of sitting on top of it. Q: How do I make a Halloween costume video with AI? A: Film a short clip of yourself in plain, fitted clothes — a walk, a turn or a dance step — then run Change outfit once per costume: vampire, witch, skeleton suit, astronaut. Because every result keeps the original timing, you can cut between the plain take and the costumed one on the beat for a costume-switch reveal. Q: Can I turn myself into a superhero in a video? A: Yes, with an original design. Describe the suit — colours, armour or fabric, cape, emblem shape — or add concept art as @image1. Famous comic and film suits are trademarked by their owners, so design your own hero, especially for anything you publish or use commercially. Face covered by a mask? Use Replace character instead. Q: What if the costume covers the face, like a mask or helmet? A: Use Replace character. Change outfit is built to keep the face identical, so it won't put on a full mask, helmet or creature head. Replace character takes the whole look — face, body, costume — from your reference image while keeping the performance, so a picture of the fully costumed character becomes the new figure in your clip. Q: Can it add a prop like a sword, wand or shield? A: If you already hold something in the clip, yes: Swap object can turn a broom handle into a wand or a stick into a sword, keeping your grip and movement. Costume accessories that are worn, like belts, crowns or capes, belong in the Change outfit description. Genjutsu doesn't erase objects, so a prop you hold stays unless it's swapped. Q: Does it work for cosplay previews? A: Yes. Cosplayers can film a pose routine and preview a costume from concept art or a fabric mock-up before buying materials or sewing. Add references from the front, side and back so the costume holds through turns. It's a visual preview — it says nothing about real fit, sizing or how a costume will feel to wear. Q: Is it OK to put a costume on someone else in a video? A: Only with their permission. Edit footage you own or are licensed to use, and only people who agreed to the change. Don't use celebrities or real people without consent, don't impersonate anyone, and keep costumes respectful — label the result as AI-edited when you share it, so viewers know it isn't real footage. ## Related pages - AI Video Editor: https://kenerateai.com/ai-video-editor - Change a shirt in a video: https://kenerateai.com/change-shirt-in-video - AI clothes changer: https://kenerateai.com/ai-clothes-changer - Put yourself in a movie: https://kenerateai.com/put-yourself-in-a-movie-ai - Character swap AI: https://kenerateai.com/character-swap-ai ## Sources - Kenerate Genjutsu (video editor): https://kenerateai.com/app/genjutsu
