2D Comb Description

The 2D Comb VirtualDub filter was designed for removing color / luma fluctuations between adjacent rows. It was intended to be a better chroma comb filter, which in most capture cards is simply averaging the chroma signal of consecutive lines and so is reducing the vertical color resolution. This filter does the same job of removing color phase artefacts but with less reducing the vertical resolution. I find it to be useful also for removing luma fluctuations.
