Description

Jinc (EWA Lanczos) resampling plugin for AviSynth 2.6 / AviSynth+.

This is a port of the VapourSynth plugin JincResize.

SSE / AVX Intrinsics taken from the other AviSynth plugin JincResize.

Requirements:

• AviSynth 2.60 / AviSynth+ 3.4 or later

• Microsoft VisualC++ Redistributable Package 2022 (can be downloaded from here)

Usage:

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", string "cplace", int "threads", int "opt")

There are 4 additional functions:

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).

Jinc36Resize / Jinc64Resize / Jinc144Resize / 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", string "cplace", int "threads")

Parameters:

• clip
  A clip to process. All planar formats are supported.

• target_width
  The width of the output.

• target_height
  The height of the output.

• src_left
  Cropping of the left edge.
  Default: 0.0.

• src_top
  Cropping of the top edge.
  Default: 0.0.

• src_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.
  Default: Source width.

• src_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.
  Default: Source height.

• quant_x, quant_y
  Controls the sub-pixel quantization.
  Must be between 1 and 256.
  Default: 256.

• tap (JincResize only)
  Corresponding to different zero points of Jinc function.
  Must be between 1 and 16.
  Default: 3.

• blur (JincResize only)
  Blur processing, it can reduce side effects.
  To achieve blur, the value should be less than 1.0.
  Default: 1.0.

• threads
  Whether to use maximum logical processors.
  0: Maximum logical processors are used.
  1: Only one thread is used.
  Default: 0.

• cplace
  The location of the chroma samples.
  "MPEG1": Chroma samples are located on the center of each group of 4 pixels.
  "MPEG2": Chroma samples are located on the left pixel column of the group.
  "topleft": Chroma samples are located on the left pixel column and the first row of the group.
  Default: If frame properties are supported and frame property "_ChromaLocation" exists - "_ChromaLocation" value of the first frame is used. If frame properties aren't supported or there is no property "_ChromaLocation" - "MPEG2".

• opt (JincResize only)
  Sets which cpu optimizations to use.
  -1: Auto-detect without AVX-512.
  0: Use C++ code.
  1: Use SSE4.1 code.
  2: Use AVX2 code.
  3: Use AVX-512 code.
  Default: -1.
