What is AI Video Face Swap?

AI Video Face Swap lets you replace a face in any video using a reference photo. Face Swap mode changes only the face while keeping the body and clothes. Character Replace mode replaces the entire person including body and outfit. Both modes preserve the original background, motion, and audio.

How is Character Swap different from Motion Transfer?

Motion Transfer takes a still image and animates it using movements from a reference video, generating a new background. Character Swap works on your existing video footage - it replaces a person in the video while keeping the original background, lighting, and environment intact.

What video length is supported?

Face Swap supports videos up to 10 minutes. Character Replace supports up to 30 seconds with best quality under 10 seconds. Face Swap is faster and cheaper per second. Character Replace produces higher fidelity full-body replacement. Processing takes 1-10 minutes depending on length and mode.

What character styles work best?

Character Replace works best with realistic or semi-realistic character images. Photorealistic people, fantasy warriors, historical figures, and realistic costumes produce the cleanest results. Flat anime, cartoon, or highly stylized characters may blend unevenly. Face Swap works with any clear photo of a real face.
