Description

This is a very strong and fast unsharp mask with some new features.

Requirements

  • AviSynth 2.5.8 or later
  • Progressive input only
  • Supported color formats: YV12



Syntax and Parameters

UnsharpHQ (clip, int "THRESHOLD", float "SHARPSTR", float "SMOOTH", bool "SHOW")


clip   =
Input clip.


int  THRESHOLD = 20
Range: 0 to 99
The value that determines whether or not to sharpen a pixel based on the luminance change between their neighbors.
Lower values allow more to be sharpened (including noise); higher values allow less but is set to high, small detail will not be sharpened.


float  SHARPSTR = 4.0
Range: 0.0 up to 99.0
Sharpening strength; values from 2.0 to 10.0 are recommended.


float  SMOOTH = 0.5
Range: 0.0 - 4.0
The smoothing strength for pixels not being sharpened (mainly flat areas). Set to 0.0 to disable smoothing.


bool  SHOW = false
When set to true a green and black mask is shown; useful for finding an optimal value* for THRESHOLD.
Anything in green gets sharpened, anything in black is not sharpened but can be smoothed if SMOOTH is greater than 0.


*optimal value - noise vs detail trade-off. The goal is to try to sharpen as much detail as possible while not sharpening noise.


Examples

UnsharpHQ with default settings: 

AviSource("Blah.avi")
UnsharpHQ(THRESHOLD=20, SHARPSTR=4.0, SMOOTH=0.5, SHOW=false)
