AviSynth Script for Only Deinterlacing Combed Lines (MeGUI)

[AOmundson]

I'm currently attempting to upscale my collection of old anime DVDs into 1080p using VapourSynth. It's going well, except I have the issue of very noticeable combing of originally non-combed lines post-deinterlacing. My process is to first use MeGUI to deinterlace before upscaling with Waifu2x-caffe. What I'm having trouble with is finding a code block for MeGUI that will decomb the lines that need it and leave the non-combed lines and non-ghosted frames untouched.

Current MeGUI Code (Using QTGMC):

LoadPlugin("E:\MeGUI-2913-64\TDeint.dll")
LoadPlugin("E:\MeGUI-2913-64\RgTools.dll")
LoadPlugin("E:\MeGUI-2913-64\nnedi3.dll")
LoadPlugin("E:\MeGUI-2913-64\DePanEstimate.dll")
LoadPlugin("E:\MeGUI-2913-64\DePan.dll")
LoadPlugin("E:\MeGUI-2913-64\mvtools2.dll")
LoadPlugin("E:\MeGUI-2913-64\masktools2.dll")
<input>
<deinterlace>
<crop>
<resize>
<denoise>
import("E:\MeGUI-2913-64\SMDegrain.avsi")
import("E:\MeGUI-2913-64\QTGMC.avsi")
QTGMC( Preset="Slow", SourceMatch=3, Lossless=2, TR2=2 )
SelectEven()

Normally a cartoon or anime DVD should be IVTCed, not deinterlaced

If you use QTGMC and SelectEven, the framerate will be wrong, playback jerky

Did you try TFM and TDecimate ?

If you have a tricky source, post a cut sample of the source

I'm sorry to say that I'm very amateur when it comes to kind of stuff, and I'm not really sure what IVTC, TFM, or TDecimate are, much less how to use them. I would post a source sample, but this particular footage is from an ecchi series, and all the problematic segments feature large amounts of nudity.

Just find a section with steady movement and cut 10 seconds or so using DGIndex. Upload the resulting M2V here.

Upon further study, I feel like using TDeintMod with VapourSynth would work better, but I'm unsure how/if I should tweak the example script given by the mod-maker. Judging from this example clip, what you suggest I use as the command line, assuming I should change it at all?

[poisondeathray]

Your video sample is pure 3:2 (not a problematic sample)

Extract video from MKV
Index with DGIndex

MPEG2Source("1 (1) (1)-002_track1_[eng].d2v")
TFM()
TDecimate()


If you have a nvidia card and license with DGtools, you can use DGSource on MKV directly

Cool, do I need to specifically download any extra DLLs or anything to run the script, or would simply following the QuickStart guide and executing it through MeGUI be enough?

[AOmundson]

Nevermind, I figured it out. For anyone else wondering, here are the two extra DLLs you need. I extracted them into the "...\DGDecode\x64" folder along with the provided DGDecode.dll

Template Script:

LoadPlugin("...\DGDecode\x64\DGDecode.dll")
LoadPlugin("...\DGDecode\x64\TDeint.dll")
LoadPlugin("...\DGDecode\x64\TIVTC.dll")
MPEG2Source("__vid__")
TFM()
TDecimate()
#Crop(left, top, -right, -bottom)
Crop(0, 0, -0, -0)
#Uncomment the below line if your framerate is not the usual 23.976;
#the current input will have a framerate of 29.970 (the standard for most NTSC files)
#AssumeFPS(30000, 1001, false)

Once you follow the QuickStart guide steps in creating the d2v file, simply select the simultaneously created AVS file in MeGUI, and Queue it after you've made any necessary cropping.

... and Queue it after you've made any necessary cropping.

If any cropping is actually needed, you'd best stick the crop line after the IVTC.

And had you followed my suggestion, pdr wouldn't have needed to mention extracting the video from the MKV:

Just find a section with steady movement and cut 10 seconds or so using DGIndex. Upload the resulting M2V here.

Thank you, the script has been corrected
