deinterlacing anime

[mmbwdpnz]

can anybody help me properly deinterlace this footage using TIVTC? I've tried this Yadif(mode=1, order=1).SRestore() for it but it doesnt do a very good job. I'm using meGUI. The video analysis on that sucks! here is a sample of the anime footage:

QTGMC() works better than Yadif(). But you will never get perfect results when trying to undo field blendling.

I've never heard of QTGMC, its a deinterlacing filter? I actually just use meGUI to help me start the beginning of my script, then i use avsp to filter and fix the footage.

QTGMC() is a better smart bob deinterlacer than Yadif(). It uses motion compensation to... compensate for things that have moved. I seem to recall your video was MPEG. Use DgIndex to build an index file. Then:

Mpeg2Source("filename.d2v", CPU=6, info=3) # CPU=6 means deblock and dering
QTGMC() #convert to 60p
SRestore() #remove blended (preferentially) frames and return 25p

You'll need to download QTGMC() and all the filters it requires:

http://avisynth.org/mediawiki/QTGMC

QTGMC() is very slow. You can use faster settings like QTGMC(preset="fast") for faster (but not quite as good) processing. See the docs. You still won't get perfect results but it should be better than what you're getting with Yadif() -- less jaggy edges.

Why would you want to use an IVTC filter when it was never telecined in the first place?

I've never heard of QTMC, its a deinterlacing filter?

Yes, and the best one AviSynth has:

http://avisynth.org/mediawiki/QTGMC

And you'll get your best results when you go for the correct framerate:

Yadif(Mode=1)#or your favorite bobber (QTGMC)
Srestore(Frate=23.976)

thanks for all ur help! i was going to use ivtc cause im not experienced with interlacing and field blending. I had heard that ivtc was usually best for deinterlacing anime. Guess i should read more documentations.

Yeah, it looks like 23.976 is right. 25 gives a few jerks during the long panning shots.

[mmbwdpnz]

is this script correct?

No. If you had tried it you'd know already, without having to ask.

Hint: check the framerate. Also, you don't need the ColorMatrix line, nor the CPU/Info stuff (in my opinion).

For clarity, I suggest you separate all the LoadPlugins() and imports() from the working part of the script:

LoadPlugin("C:\Users\ryan\Desktop\MeGUI_dev[0.3.4.12]\MeGUI_dev\tools\dgindex\DGDecode.dll")
LoadPlugin("C:\Users\ryan\Desktop\MeGUI_dev[0.3.4.12]\MeGUI_dev\tools\avisynth_plugin\ColorMatrix.dll")
import("C:\Program Files (x86)\AviSynth 2.5\plugins\QTGMC-3.32.avsi")
import("C:\Program Files (x86)\AviSynth 2.5\plugins\Srestore.avsi")

DGDecode_mpeg2source("C:\SLAYERS_SEASON1_DISC1\VIDEO_TS\VTS_01_1.d2v", CPU=6, info=3)
ColorMatrix(hints=true, threads=0)
QTGMC() #convert to 60p
SRestore(frate=23.976) #remove blended (preferentially) frames and return 23.976p
crop(16, 0, -6, 0)
LanczosResize(640,480) # Lanczos (Sharp)

Also, functions named with the .AVSI extension in the plugins folder don't need to be manually imported. AviSynth should automatically import them when it starts up.
