[edit] Description

pSharpen performs two-point sharpening to avoid overshoot.

[edit] Requirements

[edit] Required Plugins

Additional planar colorspaces are supported when using AviSynth 2.6 and corresponding MaskTools2.

[edit] Syntax and Parameters

pSharpen (clip clp, int "strength", int "threshold", float "ss_x", float "ss_y", int "dest_x", int "dest_y")

clip   =
Input clip

int  strength = 25
Determines the strength of the sharpening (up until the overshoot correction threshold, see below). Value of 100 will set all pixels to either their local min or max; value of 0 will make the filter do nothing. Range: 0 to 100

int  threshold = 75
Determines how close to the min/max a pixel can be sharpened before the overshoot correction (compression) kicks in. Higher values make the overshoot correction more of a hard limiting, while lower values soften the compression. Value of 0 makes the filter do nothing. Range: 0 to 100

float  ss_x = 1.0
float  ss_y = 1.0
The horizontal and vertical supersampling factors, respectively. Higher values will reduce aliasing, at the expense of speed.

int  dest_x = clp.width()
int  dest_y = clp.height()
Final image size; defaults to the dimensions of the input clip.

[edit] Examples

pSharpen with default settings:

pSharpen(strength=25, threshold=75, ss_x=1.0, ss_y=1.0)
