Comment (by sghpunk):

 Seems like I was wrong, when say, that contrast in KMPlayer is the same.
 Contrast  in KMPlayer is different to. In previous test I just looked at
 screen, but KMplayer video renderer just render latest rendered pucture in
 both opened KMPlayer instances when on pause.
 Now I does "Save frame..." with KMplayer and vf=screenshot with mplayer2.
 So you can see different contrast on attached pictures.
