Interesting. I didn't know that. I'm still curious about the potential increase in quality of running gforce/gout through an iscan. It doesn't just do upscaling but also does general image enhancement apparently. I've seen some people mention iscans on this forum but in relation to laserdiscs. So regardless of whether it's avi or vob i'd love to know how much quality is improved with an iscan.
You won't ever get the best results for the GOUT using a single upscale method. Here's an example of the improvement in overall picture quality that can be achieved using one method...
Top frame is a somewhat stabalized GOUT (no antialising has been applied before upscale), the next two show two takes at an almost idental upscale method. The first is using a filter in avisynth (nnedi3), and the second is using a commercial filter (Video Enhancer). Both are resized using the same method (Spline36Resize), both have the same simple filters applied to the upscale. As you will see there is almost no difference between nnedi3 and VE; however while these filters work well on some shots, they work terrible on others. Garbage-in-garbage-out, both display problems handling the ghosting trails left by the DVNR and both also have trouble in some space scenes. Furthermore VE cannot be used as a frameserver (although you can use avisyth filters within the program itself) which makes nnedi3 far more attractive.
