Thanks for the scripts, DrDre. First off, wow, those rendering times can be really frustrating when you have to wait a few minutes for one frame!
I have played around quite some time with the v12 script. Replaced NNEDI2 with NNEDI3 at some points (not all, as some delivered worse results) and tried different QTGMC settings.
More or less subtle difference depending on the frame, but it is there:
(note that I only have the trial of Video Enhancer and for a good comparison I used it in the frames for the "untouched" script too)

What do you all think?
I think I will soon look into how much the script can be sped up because I guess that the changes have increased rendering times.
