DJ's version has had substantial grain reduction and anti-alising applied before upscale and getting that right is definatly the key to improving the upscale result; however as I mentioned you still need to handle different types of scenes differently, espcially space scenes and scenes where the DVNR was very heavy.

I wrote the script for V2 and there was no grain reduction at all in the script, and no antialiasing before the upscaling. The key for detail preservation vs jaggies reduction was to upscale before doing the processing.

Here is that scene with some grain removal and aa applied to the raw PAL gout (notice how the framing is slightly different, I would expect better success for NTSC especially in regards to anti-alising). NNEDI3 is then applied.

Yeah, the NTSC has more detail intact than the PAL. Weird.

In that picture you posted there is way too much detail being removed by the antialiasing though. (plus it's the PAL version)

I can tell you from experience that generally, EEDI2 gives a much better result when done in multiple passes with tweaked settings than NNEDI2 and NNEDI3 will ever do.

Especially if you use a plugin called QTGMC with EEDI2 as antialiaser:
