I did not find the functions of cleaning the frame from film noise (dedot, despot and etc.) points and scratches. Without this, video restoration does not have the proper quality even when zooming. Think about this function, it is necessary!
Removing scratches and other spots and dirt has never been part of this program from what I can see. People that restore video often do that externally, removing spots and scratches with a despeckler in a different video software or by hand and frame by frame.
