Part 2: The Comb Filter

... I find 3D comb filter artifacts ... more objectionable than the composite video artifacts ... that a 3D comb filter is designed to remove from stationary frames. ... OTers who love 3D comb filters can always use a Leitch DPS-475/575 or tritical's TComb on the raws I'll be posting to Usenet.

So, for the present, only 2D comb filtering works without undesirable side-effects on moving picture areas that 3D filters generate. What about your research into the idea of a "counter-phase overlay", as a better comb filter technique for moving picture areas?

[BTW, to get up to speed on 2D/3D comb filters, see Extron Electronics' single page write-up NTSC Decoding Basics (Part 4) -- http://www.extron.com/company/article.aspx?id=ntscdb4 .]
