Description

Jinc (EWA Lanczos) resampling plugin for AviSynth 2.6/AviSynth+.
JincResize v1.0.0 and greater is a port of the VapourSynth JincResize filter with SSE / AVX Intrinsics taken from the original JincFilter by innocenat.

JincResize includes 5 functions:

• JincResize is the main filter.
• Jinc36Resize is an alias for JincResize(tap=3).
• Jinc64Resize is an alias for JincResize(tap=4).
• Jinc144Resize is an alias for JincResize(tap=6).
• Jinc256Resize is an alias for JincResize(tap=8).

Requirements

• [x86]: AviSynth+ or AviSynth 2.6
• [x64]: AviSynth+
• Supported color formats: Y8, YV12, YV16, YV24, YV411
  • AviSynth+: all planar formats (8/10/12/14/16/32bit, Y/YUV/RGB with or without alpha) are supported.

Syntax and Parameters

JincResize (clip, int target_width, int target_height, float "src_left", float "src_top", float "src_width", float "src_height", int "quant_x", int "quant_y", int "tap", float "blur", int "opt")

Jinc36Resize (clip, int target_width, int target_height, float "src_left", float "src_top", float "src_width", float "src_height", int "quant_x", int "quant_y")

Jinc64Resize (clip, int target_width, int target_height, float "src_left", float "src_top", float "src_width", float "src_height", int "quant_x", int "quant_y")

Jinc144Resize (clip, int target_width, int target_height, float "src_left", float "src_top", float "src_width", float "src_height", int "quant_x", int "quant_y")

Jinc256Resize (clip, int target_width, int target_height, float "src_left", float "src_top", float "src_width", float "src_height", int "quant_x", int "quant_y")

clip   =

A clip to process. All planar formats are supported.

int   =

target_width: the width of the output.

int   =

target_height: the heightof the output.

float  src_left = 0.0

Cropping of the left edge.

float  src_top = 0.0

Cropping of the top edge.

float  src_width = Source width

If > 0.0 it sets the width of the clip before resizing.

If <= 0.0 it sets the cropping of the right edges before resizing.

float  src_height = Source height

If > 0.0 it sets the height of the clip before resizing.

If <= 0.0 it sets the cropping of the bottom edges before resizing

int  quant_x = 256

int  quant_y = 256

Controls sub-pixel quantization.

Must be between 1 and 256.

int  tap = 3

Corresponding to different zero points of Jinc function.

Must be between 1 and 16.

This parameter is for JincResize() only.

float  blur = 0.0

Blur processing, it can reduce side effects.

To achieve blur, the value should more than 0.0.

Must be between 0.0 and 10.0. Default: 0.0.

This parameter is for JincResize() only.

int  opt = 2

Controls the used CPU optimizations.

• 0 : Use C++ routine.
• 1 : Use SSE routine (SSE4.1 required).
• 2 : Use AVX routine (AVX2 required).

Default: 2, if AVX not available 1, if SSE not available 0.

This parameter is for JincResize() only.

Examples

Upscale to 1920x1080:

AviSource("Blah.avi")
Jinc36Resize(1920, 1080)  # same as JincResize(1920, 1080, tap=3) or JincResize(1920, 1080)
Jinc64Resize(1920, 1080)  # same as JincResize(1920, 1080, tap=4)
Jinc144Resize(1920, 1080) # same as JincResize(1920, 1080, tap=6)
Jinc256Resize(1920, 1080) # same as JincResize(1920, 1080, tap=8)
