Swap a face in a video

Share a clip and a face, or a saved character. The skill replaces the face and hair in every frame while the performance (pose, motion, expressions, lips) and the scene stay. Cherry 2 Pro by default.

FAQ

Frequently asked questions

Is it the same as the Video Face Swap app?

Yes. The skill sends the Video Face Swap app’s own prompt with the same models and defaults, so your agent gets the app’s results from a chat, and can run it on many images in one go.

How long can the clip be?

Cherry 2 Pro takes clips of 4 to 30 seconds, and the result keeps the clip’s length and shape. For a shorter clip the skill offers Lemon, which takes 1 to 15 seconds.

What makes a swap hold up?

A short clip with a steady, clearly visible subject and a front-facing face image. Fast motion, profile turns, and things passing in front of the face are the hardest.

Can I use a real person’s face?

Only with that person’s permission, and never to deceive, harass, or sexualize anyone. Harmful deepfakes are forbidden on Mage, and the skill states the rule with the price before it runs.

Why does it ask before rendering?

Video is priced by resolution and length, so the skill quotes the model, resolution, length, and Gems and waits for your yes. It starts at 480p, the cheapest, and offers 720p or 1080p for a final.
