AI Face Swap for Video, Calibrated for Realism
Our AI face swap allows you to insert a person's face in a video with a natural looking result rather than generated. You simply upload a clear source photo and a target video, and we do all the work for you. No experience with editing needed.
What sets us apart from most other face swapping applications is our calibration-first process. Prior to placing your face in a single frame of the video, our AI analyzes your source photo to create a model of your facial geometry, skin tone, and light conditions.
How Does Our AI Face Swap Tool Work?
- Image calibration — You upload a clear photo of yourself taken facing forward. The AI finds the key points on your face, develops a 3D representation, and prepares the data for transfer to video frames.
- Video generation — You upload a target video file in MP4, MOV, or WebM format (up to 4K), and the AI transfers the prepared face data to each individual frame.
Each face swap costs 2 credits. One credit for AI image calibration and one for video generation. Credits don't expire.
