Description

Jinc (EWA Lanczos) resampling plugin for AviSynth 2.6/AviSynth+.
JincResize includes 4 functions — Jinc36Resize, Jinc64Resize, Jinc144Resize, and Jinc256Resize, which is a 3-tap, 4-tap, 6-tap, and a 8-tap filter respectively.

Requirements

• [x86]: AviSynth+ or AviSynth 2.6
• [x64]: AviSynth+
• Supported color formats: Y8, YV12, YV16, YV24, YV411

Limitations

• Downscaling is not currently implemented. Not true with r44, only previous versions.

Syntax and Parameters

Jinc36Resize (clip, int, int, float "src_left", float "src_top", float "src_width", float "src_height", int "quant_x", int "quant_y", bool "version")

Jinc64Resize (clip, int, int, float "src_left", float "src_top", float "src_width", float "src_height", int "quant_x", int "quant_y", bool "version")

Jinc144Resize (clip, int, int, float "src_left", float "src_top", float "src_width", float "src_height", int "quant_x", int "quant_y", bool "version")

Jinc256Resize (clip, int, int, float "src_left", float "src_top", float "src_width", float "src_height", int "quant_x", int "quant_y", bool "version")

clip   =

Input clip

int   =

Target width

int   =

Target height

float  src_left = 0

float  src_top = 0

float  src_width =

float  src_height =

Optional crop syntax is the same as AviSynth's internal resizers.

int  quant_x = 256

int  quant_y = 256

Control sub-pixel quantization.

bool  version = false

Setting it to true will show Jinc's internal CPU flag and instruction support it compiles with. More information here.

Examples

Upscale to 1920x1080 with Jinc36Resize:

AviSource("Blah.avi")
Jinc36Resize(1920, 1080)

Version      Date            Changes

r44          2014/09/20      - Latest revision r44 (@0cd502a)
                             - More correct calculation on quantized pixel
                             - Fixing some memory leak
                             - Implement basic downscaling support.
                             - Better memory performance
                             - Cleanup + const qualify more variable
                             - x64 binary
                             - Compiled with Intel Parallel Studio XE 2015 Composer Edition for C++

v0.2         2014/07/27      - Core rewritten to use quantized lookup table for coefficient.
                             - Support SSE2, SSE3, AVX2 and FMA3.
                             - Basically, MUCH faster.
                             - Add Jinc144Resize which is 6-tap filter.
                             - Add quant_x, quant_y, and version parameters.

v0.1.1       2013/11/26      - Binary is now compile with ICC14
                             - More optimized code, should run much faster.
                               Thanks to tp7 and others for optimization tips.

v0.1         2013/11/26      - Initial release
