Description

This filter implements the same warp sharpening algorithm as aWarpSharp by Marc FD, but with several bugfixes and optimizations.
In addition to the complete aWarpSharp2 algorithm, parts of the algorithm are also available as aSobel, aBlur, aWarp and aWarp4. This allows for more advanced processing.


Requirements

- AviSynth 2.5.8 or later
- Progressive input only
- Supported color formats: YV12
- MMXExt capable CPU, blur will be more precise around frame borders if SSSE3 is available.


Filters

Filter Description Color format
aBlur

A blurring filter.

YV12
aSobel

An edge dectecion filter.

YV12
aWarp

A warp-sharpening filter.

YV12
aWarp4

Unlike aWarp, this uses a 4x larger source clip than the edgemask. This is useful for improving subpixel interpolation quality of the final step.

YV12
aWarpSharp

Special fuction that keeps compatibility with ancient scripts that use the original aWarpSharp.

YV12
aWarpSharp2

The same as aWarp(aSobel().aBlur()) but a bit faster.

YV12


Changelog 

Version           Date             Changes

2012.03.28      2012/03/28       - Added new final part aWarp4 that takes 4x upsampled source for better final subpixel interpolation.
                                   - aWarpSharp2 can now be also called by aWarpSharp() with internal parameters conversion for compatibility 
                                     with ancient scripts. Direct aWarpSharp2 call is encouraged though.
                                   - New chroma values: 5 and 6: the same as 3 and 4, but luma isn't processed and just copied. Useful for 
                                     filtering sources with certain chroma problems.
                                   - Changed some defaults.

2009.06.19      2009/06/19       - renamed main filter from aWarpSharp to aWarpSharp2 for less confusion with original aWarpSharp
                                   - fixed wrong offsets in Warp
                                   - added new blur type - produce better quality, but around 2.5x slower
                                   - blur will be more precise around frame borders if SSSE3 is available
                                   - some optimizations, mostly noticeable on Core2
                                   - removed support for undocumented parameters of original aWarpSharp

2009.05.24      2009/05/24       - Initial release
