If you want to make a person look old through video, there are two schemes:
1. Use Tik Tok's filters and special effects. Choose a filter or special effect that can make your face look older, such as dark skin, wrinkles or age spots, and apply it to the video to make your face look older. At present, there are some AI face-changing software on the market, which can turn one person's face into another person's face. In this way, young people's faces can be replaced by old people's faces, which makes them look older. However, this technology needs certain technical and equipment support, which may have a certain impact on video quality.
