@poisondeathray: Of course having artefact free raw material is better. However most ordinary videographers will have some in-camera compression, nowadays usually h.264 and .mov if it is a mainstream dslr. Nevertheless some of those are looking for better sharpening than in-camera. I already achieved much better sharpening using avisynth, which is our discussion here.

What you said about EDIUS is interesting: I do not know if the algorithm they use inside is RGB. But I tried out my initial unsharpmask code and replaced bionomialblur() with gaussianblur(). Gaussian also delivers good results, but contrary to binomialblur() it allows the code to run with RGB (canopus codec exports the MOV as an AVI in YUY2) like this:

x=avisource("blabla.avi").convertToRGB24
i=x.gaussianBlur()
...

Result: Again magenta artefacts. Mmmmhhhhhh.....
