Description

BWDIF (Bob Weaver Deinterlacing Filter): motion adaptive deinterlacing based on yadif with the use of w3fdif and cubic interpolation algorithms. This is a port of the VapourSynth plugin Bwdif.

Requirements

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

• Microsoft Visual C++ 2019 Redistributable Package (x86 / x64)

*** vcredist_x86.exe is required for BWDIF-x86

*** vcredist_x64.exe is required for BWDIF-x64

Syntax and Parameters

BWDIF (clip, int "field", clip "edeint", int "opt", float "thr", bool "debug", bool "pass")

clip   =

A clip to process. All planar formats are supported.

int  field = -1

Controls the mode of operation (double vs same rate) and which field is kept.

• -2 : Double rate (alternates each frame), AviSynth internal order.
• -1 : Same rate, AviSynth internal order.
• 0 : Same rate, keep bottom field.
• 1 : Same rate, keep top field.
• 2 : Double rate (alternates each frame), starts with bottom.
• 3 : Double rate (alternates each frame), starts with top.

clip  edeint =

Clip from which to take spatial predictions. This clip must be the same width, height, and colorspace as the input clip.

If using same rate output, this clip should have the same number of frames as the input. If using double rate output, this clip should have twice as many frames as the input.

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.

float  thr = 0.0

Threshold for interpolation.

If the difference between pixels of the prev/next frame is less than or equal to this, the resulted pixel wouldn't be interpolated.

Must be between 0.0..100.0.

100.0: No interpolation is performed.

Default: 0.0.

bool  debug = false

Whether to show which pixels will be interpolated.

Default: False.

bool  pass = false

Whether to return the source frame (repeated when double rate) when _FieldBased is 0.

Default: False.

Examples

BWDIF with default settings:

AviSource("blah.avi")
BWDIF(field=-1, opt=-1, thr=0.0, debug=false, pass=false)
