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

• AviSynth 2.6.0 Alpha5 or later
• AviSynth+ r1576 or later
• Supported color formats: Y8, YV12, YV16, YV24, YV411

Limitations

• Downscaling is not currently implemented.

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:
