Older / younger faces (Face age) Desktop app
In the desktop app the Face age add-on (Settings > Tools > AI add-ons; SAM with StyleGAN2, about 1.1 GB) makes the faces in a picture or a video look older or younger. Ask in the chat with a picture or video: "make me look 80", "make us younger", "as a child", "gjør meg eldre", "hazme un niño" -- or add the Age part in Media Studio: Look about (5-95 years, or Child, Teen, Young, Middle-aged, Older, Old), Strength, Change the face or the face and hair (grey hair shows), all faces or one person, and Try on this frame to see it on the moment shown before the whole clip runs. In a video each face is followed and the change held steady. Faces turned far from the camera are left as they are. It runs on this computer; nothing is sent. The licence is non-commercial only (the StyleGAN2 FFHQ weights and FFHQ), and it is only for faces of people who agreed; results are labelled (-age70 in the name, "AI age change to about 70" in the file). The web version doesn't have it.
