@RU.08: I'm sorry if I misunderstood your intentions. Maybe we just have different preferences when it comes to upscaling.
Perhaps. I believe EEDI2 will give the best results for (at least) most scenes in ANH, and I can't believe I let it slip me by until you mentioned it. But I certainy don't agree with using it to scale horizontally, a straight splineresize would work better then using EEDI2 horizontally, and now that you've mentioned it the "pattern" it introduces when used in both directions is pretty much unmissable. Anyway, I'm going to see how EEDI2 goes on Robocop Criterion now; that DVD has a lot of the same problems as ANH (DVNR and alising) and the fact that I'm not working with an upscale will mean I should get good results (except for robovision scenes, obviously), I'll make a new thread once I have a script looking good, and I'll come back to SW (ANH & ESB) once I have the NTSC version. :) Yes, I'll make my own thread when I feel I have a compentent script. :)

What's the idea behind using qtgmc after the first eedi2?
DE
Good question! EEDI2 doubles the vertical resolution and each new line is an interpolation, but the way that EEDI2 works it tries to join "lines" like diagonal lines together (in the new lines), and that in itself very effectivly reduces the "jaggies". It is not designed to work horizontally, but you can force it to by using turnleft, etc. EEDI2 does not modify the original lines which let's say are now the "odd lines" and the new ones being the "even lines", it only creates new lines. qtgmc is an advanced deinterlacer, but a very slow one, and will reduce the jaggies in the image without resizing; so essentially using it is hitting the image with a second "deinterlacer". You wouldn't want to use it before EEDI2 because then it's "damaging" the original picture before resize; plus the fact that EEDI2 already does a lot of the work for you means you really only need a much lighter touch with a deinterlacer post-eedi2. And as I've already mentioned I don't think EEDI2 should be used to stretch the picture horizontally because it then "joins more lines together" and your image comes out looking like it is made up of crisscross strokes. And sorry for missing your question the first time. :)
