Film Restoration with Avisynth

Hello! I am part of a group that is working on a 4K fan restoration of a Godzilla film! I looked into things like Phoenix and PFCLean, but all of those were far too expensive for our purposes. I then looked into avisynth scripts, which seemed like a good option. However, I don’t know the first thing about coding or scripts. Harmy gave me some scripts he used, but, as I said, I’m not too knowledgeable about codes. I have avisynth installed, as well as VirtualDub, but I can’t get the avs scripts to work in VDub, or avsmpod. Unless someone knows how to get a cheaper version of Phoenix Refine, I’m in need of some help. Thanks!
