How to take a Hitchcock zoom with a mobile phone?

Move back with the mobile phone (that is, the person moves back), and push the lens forward (control the screen to slowly enlarge the focal length. Here, you need to fix the focal length before shooting an object), so as to ensure constant focus, no loss of focus and stability (considering the use of PTZ, stability is very important). It can be changed from a telephoto lens perspective to a wide-angle lens perspective, or from a wide-angle lens perspective to a telephoto lens perspective.
