<description>Adaptive sharpenning strength. If D>0, adaptive thresholding is enabled. The threshold is adapted for each pixel (bigger for edges) if adaptive sharpenning is enabled, T acts like a maximum. (value clamped to [disabled=0..16])</description>
<description>Block adaptive sharpenning. If B>=0, block adaptive sharpenning is enabled. It acts very simply, by lowering the threshold around DCT-blocks edges. (It works only with adaptive sharpenning, when D>0) (value clamped to [disabled=0..4])</description>
<description>High quality block filtering. (aka block based adaptive thresholding.) Try with and without on a blocky video... very powerfull. It works only with adaptive thresholding ( D > 0 )</description>
