Description
blah; a sharpening function.
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.
- MaskTools2
- MedianBlur or MedianBlur2
RemoveGrain and Repair - part of the RemoveGrain v1.0b package.- RgTools - recommended drop-in replacement for RemoveGrain & Repair!
Syntax and Parameters
Defaults are intended for strong sharpening on 2x upscaled material. For normal sharpening, set de to 0.02, str to 3 and cstr to 0.75 and go from there. The failure modes are as graceful as I can reasonably get them, considering the strength of the sharpening required. Also, the degree of sharpening that can be "gotten away with" varies pretty wildly by source.

- clip =
- Input clip
- clip =
- int str = 4
- int strv = str
- intt strh = str
- str = strength of highpass sharpening default 4
- strv = vertical version of str defaults to str
- strh = horizontal version of str defaults to str
- int str = 4
- float de = 0.2
- float dev = de
- float deh = de
- de = de-emphasis strength default 0.2
- dev = vertical version of de defaults to de
- deh = horizontal version of de defaults to de
- float de = 0.2
- float re = de/2
- float rev = re
- float reh = re
- re = re-emphasis strength defaults to de/2
- rev = vertical version of re defaults to re
- reh = horizontal version of re defaults to re
- float re = de/2
- float cstr = 0.5
- float cstrv = cstr
- float cstrh = cstr
- cstr = strength of contrast sharpening default 0.5, values above 1.0 will cause halos
- cstrv = vertical version of cstr defaults to cstr
- cstrh = horizontal version of cstr defaults to cstr
- float cstr = 0.5
Examples
blah with default settings:
AviSource("Blah.avi") blah(str=4, strv=4, strh=4, de=0.2, dev=0.2, deh=0.2, re=0.1, rev=0.1, reh=0.1, cstr=0.5, cstrv=0.5, cstrh=0.5)
