Description

vsLGhost: Luminance Ghost reduction filter. Can be used for removing luminance ghost or edge ghost (ringing).

This is a port of the VapourSynth plugin LGhost.

See LGhost for the original AviSynth plugin.

Requirements

• [x86/x64]: AviSynth 3.6 or greater is required in order to use this filter.
• Supported color formats: Y8, YV12, YV16, YV24, YV411
  • AviSynth+: all planar formats (8/10/12/14/16/32-bit, Y, YUV(A), and RGB(A) with or without alpha) are supported.

Syntax and Parameters

vsLGhost (clip, int[] mode, int[] shift, int[] intensity, int "y", int "u", int "v", int "opt"))

clip   =

A clip to process. All planar formats are supported.

int[]  mode =

Ghost removal mode.

• 1 : Edge
• 2 : Luminance
• 3 : Rising edge
• 4 : Falling edge

int[]  shift =

Width to shift.

Must be between -width and width (exclusive).

int[]  intensity =

Strength.

Must not be 0 and must be between -128 and 127 (inclusive).

int  y = 3

int  u = 2

int  v = 2

Planes to process.

• 1 : Return garbage.
• 2 : Copy plane.
• 3 : Process plane. Always process planes when the clip is RGB.

int  opt = -1

Sets which cpu optimizations to use.

• -1 : Auto-detect.
• 0 : Use C++ code.
• 1 : Use SSE2 code.
• 2 : Use AVX2 code.
• 3 : Use AVX512 code.

Each ghost consists of individual value from mode, shift and intensity.

For example, vsLGhost(mode=[2, 2, 1, 1], shift=[4, 7, -4, -7], intensity=[20, 10, -15, -5]) corresponds to four ghosts.

The first ghost is (mode=2, shift=4, intensity=20), the second ghost is (mode=2, shift=7, intensity=10), and so on.

Examples

AviSource("blah.avi")
vsLGhost(mode=[2, 2, 1, 1], shift=[4, 7, -4, -7], intensity=[20, 10, -15, -5])
