QTGMC Deinterlacing Script (v3.32)

Yes, QTGMC does "take both fields into account" (and more) even if you keep single rate. Every output frame is constructed from a range of neighbor fields as Didée has noted. By default the current field is interpolated into a full frame, then the two fields before and after (interpolated + motion compensated) are combined into the frame in such a way as to remove bob-shimmer. This temporal processing also enhances detail to some degree and has some noise reducing effect.
So all source data will have been used in your output even after a SelectEven(). The result will be primarily based on the even fields of course, but the neighboring ("thrown away") fields will have had an influence too.
