Indeed, I just reached that part of the guide today. It was a bit disjointed as it was located under Post Production.

At any rate, I think the majority of the footage looks pretty good. (Pretty good.)

I've noticed that there is a bit of banding in a few of the darker areas, though. I told AviSynth to ignore all of the filters (expect the IVTC and Resize stuff) in order to see what the original image looked like, and it too had some banding in it, though not as much. It seems Deen is accentuating the banding, even with the lower settings I'm using. Is there anything to do for that except either remove Deen or just try to avoid darker scenes? (Or just use such things anyway?)

Banding.
Banding2.

And my current script:

Code: Select all

MPEG2Source("F:\Stuff\DVD Rips\Ah! My Goddess\DGIndex Project Files\AMG 001.d2v")
deint=TDeint(mode=2,mtnmode=3,blim=100)
TFM(cthresh=4,slow=2,clip2=deint)
TDecimate(mode=1)
VagueDenoiser(threshold=2,method=1,nsteps=6,Wiener=true,chromaT=2.0)
RemoveGrain(mode=5)
RemoveGrain(mode=5)
Deen("w3d",2,4,4)
FluxSmoothST()
LimitedSharpenFaster()
vmToon(Sharpen=false,Strength=20)
Crop(8, 0, -8, -0)
LanczosResize(848, 480)
ConvertToRGB24()
I put the VagueDenoiser in there just to try it out, and it did get rid of a good bit of noise in some places. (Like on the outside of that glow in the first image.)
I switched to vmToon instead of Toon since I could turn the sharpen function off.
I resized to 848x480 since I want to keep the widescreen aspect ratio.
And finally, I put in the ConvertToRGB24 because I don't plan on distributing this anywhere but online, so I figured I may as well edit in RGB.
... yea ...

as far as I know, it's just a side effect of smoothing.
Had a similar problem with my LE footage for gateway

you may want to search http://forum.doom9.net for a function called gradfun2db.
From the limited experience I have with it, it'l take care of that problem (put it after the smoothers)...but it hurts compressability (add limitedsharpenfaster(Edgemode=-1) at the end of your script to see the noise that it puts back into your clips)

I thought gardfun2b was not meant to be used for prepossessing, but only during playback?

Hm, Sereenie is right. I looked it up on doom9 and it's intended to be a real-time playback filter. At any rate, most of it isn't too bad, so I think I can live with it. I tweaked a few minor things in the script and I think it looks a little better now, so I think I'll go ahead and work with what I have. Maybe it's not godly perfect, but I certainly don't think it can be called bad.

Thanks for putting up with all of my questions, Kariudo. You're help has certainly been invaluable. When I actually get a finished product out, I'll be sure to thank you somewhere in there ;) . (Unless you're against that for whatever reason. >_>) Just don't expect a final to be out any time amazingly soon. I'm hoping for late summer or so. :\

Again, thank you. (^_^)

i can relate to your problem, i don't like looking at oversmoothed images. you get areas of solid colors that float around and make the video look watery. try lowering the strength of the smoother or using different filters.

i didn't had problems with deen, but i did with mftoon.
