msycamore: Speaking of 3D comb filters, do you notice any checkerboarding on the first frame of a sharp scene/shot-change?
The user poita and I have been looking at different 3D comb filters and we've seen this artifact a lot.
My Panasonic DMR-ES10 has an amazing 3D comb filter, but it exhibits an ugly checkerboard artifact on the first frame of any sharp scene/shot-change.
