I hate to propose changes to the script at this late of a date, but I've been playing around with something lately that might really be useful.

Currently two NNEDI2 calls are used to antialias, and assumingly remove any remaining combing artifacts (or line shimmer.)

qtgmc() is a deinterlacing filter that is a more updated riff on TempGaussMC, and has a progressive processing component.

It is not nearly as slow as when processing field based video. I calculated about 12x faster than using it as a field deinterlacer. (And MUCH faster than a double NNEDI2 call.)

This filter identifies edges/lines, cleans them and is really robust without destroying detail or creating new artifacts.

The basic usage for this is: qtgmc(Preset="Slower", InputType=1)

I don't have GOUT discs ATM to test this on, but since I've heard chatter that there are still some artifacts remaining after the current version of script, I was wondering if someone wanted to give it a try as a faster more effective answer.
