AI Face Swap Video: Recast Your Footage with One Photo
Attach a photo of the person you want on screen, and the AI recasts your clip with them. The gestures, expressions and timing of your clip guide the new version, so it usually stays close to the original performance and you can test a new cast without a reshoot. Your original stays as it was.
Powered by leading AI video models
Edit with the leading video models that read a clip as a reference, with no API keys, no setup and no switching tools.
An AI face swap built on your original performance
Most face swap apps paste a face over the original and hope the edges hold. Here the AI rebuilds the person from your photo inside the shot, with hair, skin tone and light that fit the scene, while the movement comes from your clip.
Models that read video
A recast needs a model that can take your clip and a photo as references. Only those appear here, so any option you pick works from your footage.

One clip, many casts
Recast the same short clip with three different people to compare them side by side. Every version saves as a new video next to your original.
Start from one face photo
A clear, front-facing photo is all the AI needs. Attach it together with your clip and ask for the swap: it rebuilds the person from the photo and aims to keep the clothes, the room and the motion from the video. Here, a presenter was recast with the woman in the photo. One generation can combine up to three clips and up to three audio tracks with your images, so you can also change the background or add music in the same pass.
What you can do with a face swap
Recasting solves more than one problem. Each of these started as an existing clip and a single face photo.
For marketers, filmmakers and educators
New faces without a new shoot
Reshooting for one change in the cast costs a day, a crew and a budget. A recast costs one generation.
Cast after you film
Shoot once with whoever is available, then try different faces on the finished take and keep the one that suits the brand or the story.
Reach more audiences
Show the same ad, lesson or announcement with presenters that each audience relates to, all made from one recording you already have.
Keep a series consistent
Use the same face photo for every clip, so a recurring character or host looks like one person across episodes filmed on different days.
How to swap a face in a video
Three steps from the clip you have to the cast you want.
1. Open your video
Open Create video and click a video you've made, or upload your clip.
2. Attach a face photo
Add a clear, front-facing photo of the new person and type the swap: "recast him with the man in the photo." Mention hair or skin details for a closer match.
3. Pick a model and generate
Choose from the available models that support videos as references and generate. The recast arrives as a new clip, and your original stays as it was.
Marketers
Recast UGC ads with different creators
One product video can become a set of ads with different faces, each holding the same product and saying the same lines. Test which presenter your audience responds to before you book a full campaign.
Use photos of creators who agreed to appear in your ads, and keep the product in the same hand and position for the closest match.
Useful for:
- UGC and creator-style ads
- Market and audience tests
- Product demos and testimonials
- Social ads in several versions.
Filmmakers
Recast a scene for previz and pitches
A scene blocked with a stand-in can become a test cut with the actor you have in mind. The AI aims to keep the costume, the light and the movement of the take while it recasts the face.
Close and medium shots with good light on the face give the most convincing recasts. Use a reference photo lit in a similar direction.
Recasting helps:
- Previz and test cuts
- Pitch decks in motion
- Casting discussions with real footage
- Short films on a small budget.
Educators
Keep a lesson, change the presenter
A recorded lesson can get a new presenter while the explanation, the gestures and the pacing stay the same. It's a quick way to refresh a course or show a presenter who fits each class.
Recasts work well for:
- Online courses and tutorials
- Training and onboarding videos
- Anonymized interviews
- Explainers in several versions.
Profile shots, fast head turns and hands over the face are where recasts work hardest. If the face drifts, rerun with a more front-facing clip or a clearer photo.

You don't need masks, tracking or editing skills. One clip and one face photo are all you need to start.
Use your own face, fictional faces, or faces of people who have agreed to appear in your video. Don't use someone's likeness without their permission or to mislead people about who said or did something.

Usually, yes. The smile, the head turns, the gestures and the mouth movement are guided by your footage, while the face, the hair and the skin come from the photo. Each clip can be up to 15 seconds long, or 30 seconds on some models.
Usually close, as long as the photo is sharp, front-facing and evenly lit. The result is a new video generated from your clip and photo, so small details like freckles or hairlines can differ.
Your original stays in your library as it was, so you can try several photos and keep the best version.
Yes. Create a fictional person with consistent AI characters, then use that image as the face photo. The same character can be recast into as many clips as you need.
Keep the take. Change the cast.
Open your clip, attach a photo of the new person, and get a recast that closely follows the original performance. Your original stays as it was, so you can try one face after another.
