Description
Small and relatively fast realtime-sharpening function, for 1080p, or after scaling 720p -> 1080p during playback (to make 720p look more like being 1080p).
It's a generic sharpener. Only for good quality sources! (If the source is crap, FineSharp will happily sharpen the crap.) ;) Noise/grain will be enhanced, too. The method is GENERIC.
Modus operandi: A basic nonlinear sharpening method is performed, then the *blurred* sharp-difference gets subtracted again.
Requirements
- AviSynth 2.5.8 or later
- Progressive input only
- Supported color formats: YV12
Required Plugins
- MaskTools2 2.0a48+
- RemoveGrain - part of the RemoveGrain v1.0b package.
- Repair - part of the RemoveGrain v1.0b package.
Syntax and Parameters
- FineSharp (clip c, int "mode", float "sstr", float "cstr", float "xstr", float "lstr", float "pstr", float "ldmp")
- clip c =
- Input clip.
- clip c =
- int mode = 1
- Range: 1 to 3
- 1 to 3, weakest to strongest. When negative -1 to -3, a broader kernel for equalization is used.
- Range: 1 to 3
- int mode = 1
- float sstr = 2.0
- Range: 0.0 up to ??
- Strength of sharpening.
- Range: 0.0 up to ??
- float sstr = 2.0
- float cstr = AUTO
- Range: 0.0 - 2.0 ?
- Strength of equalization.
- Recommended value: 0.5 to 1.25
- If all settings are left at their default value then cstr=0.9
- Range: 0.0 - 2.0 ?
- float cstr = AUTO
- float xstr = 0.19
- Range: 0.0 - 1.0 (but, better don't go beyond 0.249 ...)
- Strength of XSharpen-style final sharpening.
- Range: 0.0 - 1.0 (but, better don't go beyond 0.249 ...)
- float xstr = 0.19
- float lstr = 1.49
- Modifier for non-linear sharpening.
- float lstr = 1.49
- float pstr = 1.272
- Exponent for non-linear sharpening.
- float pstr = 1.272
- float ldmp = sstr+0.1
- "low damp", to not overenhance very small differences (noise coming out of flat areas).
- If sstr is left at its default value (2.0) then ldmp=2.1
- float ldmp = sstr+0.1
Examples
FineSharp with default settings:
AviSource("Blah.avi") FineSharp(mode=1, sstr=2.0, cstr=0.9, xstr=0.19, lstr=1.49, pstr=1.272, ldmp=2.1)
Changelog
Version Date Changes
2012/04/12 2012/04/12 - Added "ldmp" parameter, and slightly modified the (auto) cstr defaults
2012/04/08 2012/04/08 - Initial release
