Description
A warp sharpening filter. aWarpSharp implements high-quality original warp sharpening. "original" meaning the algorithm used differs on several points to other warp sharpening filters. The code is fully ISSE optimized with high accuracy.
Note: aWarpsharp is considered deprecated, aWarpSharp2 is highly recommended.
Known Issues
aWarpSharp is known to cause some color artifacts around the edges, read the following threads for more information.
- aWarpSharp edge artifacts
- aWarpSharp green artifacts on edges.
- Using BorderMirror to pad the input before using aWarpSharp.
Requirements
- AviSynth 2.5.8 or later
- Progressive input only
- Supported color formats: YV12
- ISSE compatible CPU.
- aWarpSharp (clip, float "depth", int "blurlevel", float "thresh", int "cm", int "bm", bool "show")
- clip =
- Input clip.
- clip =
- float depth = 16.0
- Range: 0.0 - 64.0
- depth determines the amount of warping. It directly affects how thin your lines will end up.
- Range: 0.0 - 64.0
- float depth = 16.0
- int blurlevel = 2
- Range: 1 - 4
- Higher blurlevel values are slower, but can give a big boost to the warp sharpening.
- If you find that the warping is distorting certain shapes too much, try lowering this parameter first.
- Range: 1 - 4
- int blurlevel = 2
- float thresh = 0.5
- Range: 0.0 - 1.0
- The bump mapping saturation setting:
- A float value of 1.0 means 100% (max).
- The default value (0.5) is recommended for maximum quality.
- If you tweak this setting, keep in mind it will enhance inequality of warping between edges.
- The bump mapping saturation setting:
- Range: 0.0 - 1.0
- float thresh = 0.5
- int cm = 3
- Chroma mode:
- 0 : disables chroma filtering
- 1 : enables chroma warping with luma bump map (recommended)
- 2 : enables chroma independent warping & bump map
- 3 : chroma -> chroma (default)
- Chroma mode:
- int cm = 3
- Note: Default in the included documentation is wrong. This wiki documentation has been revised and it's correct.
- int bm = 2
- Blur modes:
- 0 : hq 3-pass
- 1 : fast 3-pass
- 2 : fast 1-pass
- 3 : light blur
- Blur modes:
- int bm = 2
- bool show = false
- If true, it will show an edge mask; useful for adjusting depth, blurlevel.
- bool show = false
Examples
aWarpSharp with all default settings:
AviSource("Blah.avi") aWarpSharp(depth=16.0, blurlevel=2, thresh=0.5, cm=3, bm=2, show=false)
