Some DVDs (particularly low budget transfers) disappointingly have what I call 'murky' colours, that's to say towards the darker end of the spectrum everything tends to look the same greyish/brownish, while bright reds appear to come out too strong, and greens look artificial (and too dark). I the cause may be a combination of less-than-perfect original film material and poor palette choice by the DVD production technicians.
I am wondering whether there is some cunning ffdshow filter to improve this type of problem, effectively to do the same job that the DVD producers should have done in the first place. It's not simply a question of increasing saturation, brightness or contrast (on 'murky' DVDs bright colours are fully saturated, sometimes oversaturated). I find that increasing gamma can help, as can reducing overall brightness. It seems to me that with the right filters one might do more, e.g. different gamma and brightness settings for each of the 3 primary colours; more advanced colourspace corrections.
Does anyone know of any filters that can do this and has anyone had any success doing it?
