## Description

**SSSharp**; super slow sharpen.

## Requirements

- AviSynth 2.5.8 or greater
- 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

, or 1 when`ss`=true

. Usable range is 0.25 to ~8, using a`ss`=false`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.

- Sharpening iterations; higher

*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.

- Denoising iterations after sharpening; defaults to the value of

## Examples

SSSharp with default settings:

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