vapoursynth-sangnom 43.0

Single field deinterlacer for VapourSynth

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++11 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

---

• 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.

---

• 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.
