Description

Tries to clean up slight ringing around edges by heavily aWarpSharp-ing the image and then applying it only to the areas where the difference is small enough so detail isn't destroyed.

Requirements

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

Required Plugins

Latest versions of the following filters are recommended unless stated otherwise.

• aWarpSharp
• aWarpSharp2 - recommended drop-in replacement for aWarpSharp.
• MaskTools2

Syntax and Parameters

aWarpSharpDering (clip source, int "depth",int "diffthresh",int "lumathresh",int "debug")

clip  source =

Input clip.

int  depth = 32

Depth value of aWarpSharp.

int  diffthresh = 8

Differences between the source and the sharpened clip, larger than this will not be touched.

The smaller the difference the more of the sharpened clip will be used.

int  lumathresh = 32

Since the ringing is mostly notable in bright places this threshold will prevent dark areas from being hit too hard, for instance line work will be preserved.

Examples

aWarpSharpDering with default settings:

AviSource("Blah.avi")
aWarpSharpDering(depth=32, diffthresh=8, lumathresh=32)
