Swap a face from a photo into a video clip, frame by frame.
Example · made with RegiAI
Saved to your workspace history.
AI Face Swap Video puts the face from a single photo onto the person in a short video clip. It works frame by frame, so the new face follows every head turn, blink and expression in the original footage, while the hair, clothes, body and background stay as they were. You get a 720p MP4 back, usually in one to three minutes.
Video is harder than a still picture, so this tool costs $0.75 per clip of up to 10 seconds. If you only need a still image, the photo AI Face Swap costs $0.10. For a looping reaction, use GIF Face Swap, and to replace an entire person including their outfit, use AI Character Replace.

How video face swap differs from photo face swap
A photo swap only has to look right once. A video swap has to look right 24 or 30 times every second, and the face has to stay the same person across all of those frames. That is why video takes longer and costs more than a still image.
RegiAI's video tool reads the whole clip and replaces only the face, keeping the hair, clothing, pose, motion, lighting and background from the video. The output is capped at 720p and 10 seconds per run. For a longer piece, cut it into 10 second segments and run each one with the same face photo so the look stays consistent.
- Photo: AI Face Swap, $0.10, seconds.
- Video: this tool, $0.75 per clip up to 10 seconds, 1 to 3 minutes.
- GIF: GIF Face Swap, $0.75, returns a looping GIF.
- Whole person: AI Character Replace, $0.75 at 720p or $1.50 at 1080p.
Getting a clean result in motion
Most problems in video face swaps come from the source clip, not the face photo. Before you spend $0.75, check your clip against this list:
- Keep the face visible. Clips where the person turns fully away, walks out of frame or hides behind a hand will show flicker where the face comes back.
- Avoid fast cuts. One continuous shot works better than a montage with several people.
- Prefer one main person. If several faces appear, the model may pick the wrong one. For still group photos, Multiple Face Swap lets you assign each face.
- Match the face photo to the video. A face photo with similar lighting and age to the person in the clip blends better.
- Trim first. Uploads longer than 10 seconds are rejected, so cut the part you need before uploading.

Consent comes first
A realistic face swap video can be mistaken for real footage. Before you run this tool you must confirm that you have permission to use the faces. Never use it to deceive, harass, impersonate or sexualize anyone, to fake statements by real people, or to create content about someone who did not agree. RegiAI does not add a watermark, so if you share a swapped video, say clearly that it is edited.
Video deserves extra care because people tend to trust moving footage more than photos. Avoid making clips that show a real person doing or saying something they did not do, even as a joke, and never target someone who is not in on it. Laws on deepfakes and the use of a person's likeness are getting stricter in many countries, and some platforms require AI-edited video to be labeled. Check the rules of the place where you publish. Your videos stay in My creations for 30 days and you can delete them at any time.
