Description

SangNom2 is a reimplementation of MarcFD's old SangNom filter. The output is not completely but mostly identical.


What's different

  • It's open source
  • Correct borders processing
  • Additional colorspace support
  • Multithreading support
  • Requires SSE2
*Single threaded performance is mostly identical to the old version despite this plugin using SSE2.


Y8

One of the most important differences is Y8 support in AviSynth 2.6. This enables much faster anti-aliasing
(especially when used with FTurn plugin) without any chroma processing. See maa for example.


Requirements

- AviSynth 2.6.0 Alpha5 or later
- Supported color formats: Y8, YV12, YV16, YV24, YV411
- SSE2 capbale CPU


Syntax and Parameters

SangNom2 (clip, int "order", int "aa", int "aac", int "threads")


int  order = 1
Order of deinterlacing:
  • 0 : Double frame rate, top and bottom fields are kept but DoubleWeave must be called before SangNom2.
  • 1 : Single frame rate, keep top field.
  • 2 : Single frame rate, Keep bottom field.


int  aa = 48
Strength of luma anti-aliasing.


int  aac = 0
Strength of chroma anti-aliasing. The original SangNom always assumes aa=0 for chroma processing. This makes some use
cases harder to implement, so additional parameter aac was introduced. It's the same as aa but for chroma. Default value
is 0 to maintain backward compatibility.


int  threads =
Control how many threads SangNom2 uses. This plugin uses min(number of logical processors, 4) threads to do its job. In my
tests performance doesn't get any better when using more than 4 threads. Internally it uses a simple thread pool.
