Can you post a few frames of the fraps source file (vdub, video => direct stream copy ) or I suppose you can cut it with ffmpeg -vcodec copy -an with -ss (start time) and -t (duration)

There are major, major quality issues with ffmpeg's colormatrix filter - it looks like doesn't work in full chroma resolution. Even when working with YV12 (4:2:0) material , quality is noticably lower than avisynth's colormatrix (I don't know why, it was ported from avisynth)
