TComb Description

The TComb was designed to be a temporal comb filter (it reduces cross-luminance (rainbowing) and cross-chrominance (dot crawl) artifacts in static areas of the picture). It will ONLY work with NTSC material, and WILL NOT work with telecined material where the rainbowing/dotcrawl was introduced prior to the telecine process! It must be used before ivtc or deinterlace in order to work. In terms of what it does it is similar to guavacomb/dedot. It is able to filter on the first filterable frame and looks not only behind and ahead of the current frame, but at all possible combinations that include the current frame when looking for oscillation. TComb currently supports YV12 and YUY2 colorspaces. TComb does support seeking... that is, jumping to a random frame will produce the same result as if you had linearly run up to that frame. For dot crawl removal tcomb requires at least 3 static fields of the same parity and for rainbow removal tcomb requires at least 5 static fields of the same parity. Syntax: TComb (int mode, int fthreshL, int fthreshC, int othreshL, int othreshC, bool map, double scthresh, bool debug, int opt)
