Face Swap

The Face Swap node replaces the face in a video with the face from a reference image. Connect a video and a photo of the new face, and the node returns the same video with the face swapped. Use it to replace a placeholder actor, to anonymize footage, or for creative remixes.

When to use it

• Replace a placeholder actor with your final character in a storyboard video.
• Anonymize the faces in recorded footage.
• Apply the same character face across several generated clips.

Quick start

Inputs

The output, Video, is the URL of the face-swapped video.

Settings

The node runs one face-swap model, Roop, and has no other settings. The Injected references list in the settings panel shows the face images the node will send.

Example

A clip made with Generate Video, and the same clip after Face Swap. The new face comes from one studio photo, connected to Face.

The face is the photo's now: the eyes, the nose, the mouth and the shape of the face changed, and the freckles are gone. The red hair, the mustard sweater, the hand on the chin, the smile and the cafe all come from the source clip.

What changes and what stays

Face Swap replaces the face itself: the eyes, the nose, the mouth and the shape of the face. Everything else comes from the video:

• the hair, the body, the clothes and the background;
• the movement, the head turns and the expressions, which the new face follows;
• the sound, including the voice. To change the voice as well, add Voice Changer after Face Swap.

So a source clip whose hair and build already match your character gives the most convincing result.

Choose the face and the clip

A Character or a Create Face node is a good face source: its approved portrait is already a clean, front-facing picture.

Use faces you have the right to use

Swap in your own face, a person who has agreed to it, or a character you created. You must have the right to use any person's likeness that you upload or recreate, as the terms of service say. Label AI-generated content where the platforms and the laws you publish under require it.

Troubleshooting

The run stops and names a missing input. Face Swap needs both a face and a video. Connect a picture, a Character or a Create Face node to Face, and a clip to Video. The run stops before it starts, so nothing is charged.

Credits

A run costs 143 credits. When the model fails to make the video, the credits are refunded.

Tips

• Use a clear, front-facing photo. It gives the most accurate swap.
• Choose a clip with a visible face. The face in the video must be clear for the swap to find it.
• Light matters. Well-lit, high-contrast face photos give cleaner swaps.
• Keep clips short. Shorter videos finish faster.
• Generate the clip for the face. With Generate Video, ask for a person whose hair and clothes match your character, facing the camera, then swap the face in.
