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)
