Wanted another screenshot? Here you are!
GKar bicubic Vs GKar + TB merge, denoise, grainplate
http://screenshotcomparison.com/comparison/189560

Just relived my old PC, and played a bit with the latest avisynth script… what it does?

merge GKar and TB
deblock
slight color and contrast correction
denoise
upscale
grain plate

I like the overall result, but still a bit undecided about contrast… it boost some small details, but lose others; going to release a small clip to watch it in action.

Someone still interested in this project, anyway?
