AWarpSharp2

Revision as of 04:41, 8 April 2018

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 2.6 or greater
• Progressive input only
• Supported color formats: Y8, YV12, YV16, YV24

• MMXExt capable CPU, blur will be more precise around frame borders if SSSE3 is available.
• Microsoft Visual C++ 2015 Redistributable Package (vcredist_x86.exe)

1.0.0             2017/11/23       - Modifications by jpsdr
                                   - First release.

2016.06.24      2016/06/24       - Modifications by pinterf
                                   - Add 64-bit binary
                                   - Drop AviSynth 2.5x interface

2015.12.30      2015/12/30       - Modifications by cretindesalpes
                                   - Support for YV16 and YV24 colorspaces
                                   - Support for Y8 colorspace, by _08
                                   - Added parameter depthC specifying the depth for the chroma planes, by _08
                                   - Added parameter cplace to specify MPEG1 or MPEG2 chroma placement
                                   - Some crashes of the beta version hopefully solved.

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
