SangNom - VapourSynth Single Field Deinterlacer
- SangNom is a single field deinterlacer using edge-directed interpolation but nowadays it's mainly used in anti-aliasing scripts.
- This is a rewrite version of AviSynth SangNom2, and support more formats.
Build
- compiler with c++17 support
- -DVS_TARGET_CPU_X86 can enable the SSE2 code path which has a large benefit on performance
./autogen.sh
./configure
make
make install
Or
meson build && cd build
ninja
- build on linux
g++ src/sangnom.cpp -o libsangnom.dll -std=c++1y -O3 -shared -static -I/path/to/vapoursynth/headers -DVS_TARGET_CPU_X86
- build on windows
Usage
sangnom.SangNom(src, order=1, aa=48, planes=[0, 1, 2])
- the default setting, interpolates bottom field for all planes.
sangnom.SangNom(src, order=1, aa=[48, 0, 0], planes=[0, 1, 2])
- this simulates the default setting of AviSynth SangNom2
Parameter
sangnom.SangNom(clip clip[, int order=1, bint dh=False, int[] aa=[48, 48, 48], int[] planes=[0, 1, 2]])
- clip: the src clip
- 8..16 bit integer, 32 bit float support
- all color family support
- order: order of deinterlacing
- default: 1 (int)
- 0: double frame rate, must call std.SeparateFields().std.DoubleWeave() before processing
- 1: single frame rate, keep top field
- 2: single frame rate, keep bottom field
- default: 1 (int)
- dh: doubles the height of the input. each line of the input is copied to every other line of the output and the missing lines are interpolated.
- default: False (bool)
- note: if dh=True, it will force all planes to be processed.
- default: False (bool)
- aa: the strength of anti-aliasing, this value is considered in 8 bit clip
- default: [48, 48, 48] (int[])
- range: 0 ... 128
- note: the value of previous plane will be used if you don't specify it.
- note: in AviSynth SangNom2, the default is aa=[48, 0, 0]
- planes: planes which are processed
- default: [0, 1, 2]
- note: if dh=True, it will force all planes to be processed.
- default: [0, 1, 2]
Frame properties
- the output is always flagged progressive (
_FieldBased= 0) because every output line is either taken from or interpolated from a single field. - if dh=True, the
_Fieldproperty is removed since the output is a full frame and no longer a separated field.
