Assuming that you are able to download from YouTube the clip: film restoring 1967 2 videofred.mp4
You should obtain a clip with: color space: YUV420P8, bit depth: 8, resolution: 2560x954, frame rate: 18fps

In this post I attached the following files:

- film_restoring_videofred_simple.zip: contains
     1) a simplified version of FRED script using VapourSynth: film_restoring_videofred_simple.vpy
     2) the restored clip using the provided VapourSynth script : film_restoring_videofred_simple.mp4 

- Fred_Avisynth_dll.zip: contains the Avisynth dll for ColorYUV and Autolevels
  Unfortunately it is missing in VapourSynth a true replacement for these filters and is necessary to use them since most of the "magic" is performed by these filters.
  I put them in the folder "./Hybrid/64bit/Fred" fell free to put the dll where you want, but you need to adjust the path in the Vapoursynth script.

In Hybrid there are better cleaning filters, in this case I used RealESRGAN x2plus with TensorRT enabled (the first time it will take about 5min to generate the RT file cache)

The result is very near to the one provided by FREAD on YouTube (see film_restoring_videofred_simple.mp4)

I hope that this helps
