Must be loaded with Load_Stdcall_plugin("yadif.dll") or LoadCplugin("yadif.dll") (not LoadPlugin !). Do not use autoloading. (Note: in Avisynth v2.5.7 there is no need for explicit loading of Avisynth_c.dll by user for such plugins.)

Field parity of source clip must be properly set (use AssumeTFF, AssumeBFF).

Description

Port of YADIF (Yet Another DeInterlacing Filter) from MPlayer by Michael Niedermayer. It check pixels of previous, current and next frames to re-create the missed field by some local adaptive method (edge-directed interpolation) and uses spatial check to prevent most artifacts.


Requirements

- AviSynth 2.5.8 or later
- Supported color formats: YV12


Syntax and Parameters

Yadif (clip, int "mode", int "order", bool "planar", int "opt")


clip   =
Input clip


int  mode = 0
  • 0 : single frame rate, temporal and spatial interlacing check (default).
  • 1 : double frame rate, temporal and spatial interlacing check.
  • 2 : single frame rate, skips spatial interlacing check.
  • 3 : double frame rate, skips spatial interlacing check.


int  order = 1
  • -1 : field order as Avisynth assumes (default).
  • 0 : bottom field first
  • 1 : top field first


bool  planar = false
  • false : usual YV12 colorspace (default); if input clip is YV12 this parameter is silently ignored.
  • true : flag for (hacked) planar YUY2 color format of input and output clips, compatible with Interleaved2planar and Planar2Interleaved functions from the RemoveGrain (SSETools) plugin.


int  opt = 0
  • -1 : CPU optimization - auto (default).
  • 0 : slow C version.
  • 1 : Integer SSE
  • 2 : SSE2
  • 3 : SSSE3 (some)


Examples

Yadif with default settings: 

AviSource("blah.avi")
Yadif(mode=0, order=-1, planar=false, opt=-1)
