• Progressive input only
• Supported color formats: YV12

Required Plugins

Latest version of the following plugins are recommended unless stated otherwise.

• aWarpSharp
• aWarpSharp2 - recommended drop-in replacement for aWarpSharp.
• DeGrainMedian
• DCTFun4b
• MaskTools2
• RemoveGrain - part of the RemoveGrain v1.0b package.
• RgTools - recommended drop-in replacement for RemoveGrain!
• RemoveGrainHD
• VariableBlur

Syntax and Parameters

SSSharp (clip c, float "rad", bool "ssw", float "strength", int "iter", bool "ss", int "denoise")

clip   =

Input clip

float  rad = 0.25

varY (luma variance) parameter of Unsharp. rad must be a multiple of 0.25 when ss=true, or 1 when ss=false. Usable range is 0.25 to ~8, using a rad that is not close to the radius of the blurring present in your source will give sub-optimal results.

bool  ssw = true

Set to false to disable supersampled warp sharpening.

float  strength = 4.0

strength parameter of Unsharp.

int  iter = 1

Sharpening iterations; higher iter, with lower strength will give more precise masking (less halos for same sharpening) but will be very slow. Valid range is from 0 to 4, 0 disables sharpening, 4 is the maximum number of iterations.

bool  ss = true

Set to false to disable supersampled masking.

int  denoise = iter

Denoising iterations after sharpening; defaults to the value of iter. The denoise parameter is mostly to keep the the noise level in check while undergoing multiple sharpening iterations. Valid range is from 0 to 4, 0 disables denoising, 4 is the maximum number of iterations.

Examples

SSSharp with default settings:

AviSource("Blah.avi")
SSSharp(rad=0.25, ssw=true, strength=4.0, iter=1.0, ss=true, denoise=1)
