avisynth filter recommendation

[mmbwdpnz]

what filters do u recommend i use on this source? its terrible quality but the best you'll find anywhere.

...but the best you'll find anywhere.

Obviously that's not true since the XviD was made from something.

As you say, it's in bad shape. It needs deblocking (unless it's too late and the blocks were in the source before the resize), antialiasing and dot crawl removal. Among other things.

I find it arguable that this is "terrible". Look I'm not saying it's perfect, but it's certainly watchable. I've seen a LOT worse than this. If your definition of "terrible" is anything that has even minor imperfections, yes, it's "terrible". It has what monono says it has, but geez, it's not THAT bad. Well, it just depends on how picky you are. For some people this is unwatchable garbage and for some like me, it's fine. I've seen videos that truly are terrible and this one isn't even in the same ballpark as those.

For those who don't wish to download the video, it's anime.

Try this avisynth script i made

You can do better i'm sure i'm not a cartoon specialist

[jagabo]

Start with Deblock() and HQDeRing(), Santiag(), FastLineDarken(), and McTemporalDenoise(). You should also try the Xvid decoder's built in deblock and dering filters.

I see that themaster1 give a better script before I replied.

Mediainfo sez a bitrate of 1744. For those fast-motion panning shots! Okay, I've seen worse -- but while watching it, just thinking about all the work to clean it up made me want to lie down an rest a while. Looks somewhat stable until a camera pan comes along and the screen almost crackles with block noise. The sharpening ain't too bad, but the saturation and contrast look as if they might harm my monitor; I had to stop watching when I saw the sides of the histograms stretch outward.

Can you say, the usual overcooking but with malnourished bitrate??

OK, to the business at hand. Now that the bitrate has done its worst, there's not much chance for salvation in that respect without serious collateral damage. I'd start with some ColorYUV to tame the contrast and see what happens after that. But the problem with that is the sloppy color grading, so that some scenes have nearly not enough contrast to begin with, others are outta sight. Cleanup is definitely not a one-shot deal.

Variable bitrate audio, too.

thermaster1 i love you!

[mmbwdpnz]

does anyone know where i can find the dll, and avs files in themaster1's script?

[sanlyn]

you might love him, but there are lots of people on the planet who can't run his scripts. Two of my systems refused to run anything involving these plugins:

FFT3dGPU.dll
SSE3Tools.dll
RemoveGrainSSE3.dll
SSE3Tools.dll
AvsFilterNet.dll (or anything having to do with NLMeans)

At least I don 't feel alone

Try using SSE2 versions of all the SSE3 filters. Your CPUs probably don't have SSE3. FFT3dGUP probably requires a Nvidia graphics card with CUDA. You can substitute the regular FFT3D calls, they'll be slower.

[sanlyn]

I do use the SSE2's.
I know about CUDA. I know Nvidia. I will never use an Nvidia product for color work.
Nice job of re-sharpening, even for overly contrasty video. The histograms are really bustin' at the seams now ! ! LOL! But a lot of the fuzzy gunk is gone and the lines are really clean below-zero black, nice work.

Some cool masktools functions in the srcipt, I haven't seen earlier. Will keep them around. Thanks, master1.

im still missing al most all of the dlls and .avs files. I cant find half of them! please help

[poisondeathray]

im still missing al most all of the dlls and .avs files. I cant find half of them! please help

which ones ? they should be easy to find

search google for "whatever.dll" and add "avisynth" and "doom9" and it will usually be the 1st or 2nd link

if you still can't find it, list the exact dll you are missing and someone will help you out . Nobody is going to collect them for you.

histogramCMY.avs im missing

You probably don't need it - it's a monitoring filter. I had a quick look at the avs, he's one of those guys that loads a bunch of dll's that aren't actually called in the script (probably ones that he uses frequently) . Many of those dll's in his script aren't actually used

[sanlyn]

You don't need the histograms or vectorscope --at least, not all of them anyway, but probably none since many people have no interest in levels or color, they just want to denoise and sharpen.

You won't need QTGMC or AGC (they aren't called, and AGC is a disaster waiting to happen anyway).

Comment-out the above by adding a "#" character at the start of the lines involved. CHime in with any new error messages and please specify what the error is looking for and couldn't find.

yes maybe that's a better way to get him started

There are more unused than used. As sanlyn suggests I would comment out all the loadplugin, import lines at the top until an error message pops up. Then you will know what is missing and required. IMO It's no use wasting time searching around for dll's , functions, and avs's that you aren't using.

The functions/dlls you will need for sure and have to load (either autoload or load manually , or import functions) - and I might have missed some:

removegrain.dll
depan.dll
depanestimate.dll
mvtools2.dll
masktools.dll
fft3dfilter.dll
fastlinedarken.avs
awarpsharp.dll
limitedsharpenfaster.avs

The functions at the bottom of the script like TMedian2 etc,, (just copy & paste them into your script) . But some of them like EdgeCleaner and StarMask aren't actually used in this script (but it won't hurt to copy them)

[mmbwdpnz]

thank you! the colors are nasty to me so im gonna use the coloring filters. They over brightened a little.

[mmbwdpnz]

and can i post a sample of my script when im done wit it. make sure i dont need to add anything or get rid of anything. and that its done correctly.

[themaster1]

Colors are fine to my eyes and the histogram imo, maybe slightly over saturated, tweak(sat=0.9) should do the trick but feel free to experiment

[mmbwdpnz]

what setting should i do for depan and depanestimate.

I don't understand your question ? Why are you asking that - is something specifically wrong ? Were you using themaster1's script or something else ? You can use that as a starting point and adjust it to however you like

[sanlyn]

Whew! Master1, only took 2.5 hours to match that script to my old-fashioned setup and disable unnecessary lines.

Looks good (slow as hell, but what else is new with Avisynth?). Actually, ran somewhat faster than I thought it would and I'm not using CUDA or set up for slaughterfest gaming (PAC-MAN is my limit). Some good ideas to learn from.

[themaster1]

You gotta thank poisondeathray for the mvtools (complicated part) i have tweaked it a little it work well on many (crappy) sources, see here

Yep, I recall making a copy of that thread. I keep going back to it. One of these days I'll have it figured out in detail.

[mmbwdpnz]

i have one problem with the script. there is a green mask over the video.

[mmbwdpnz]

does it look done correctly as well?

[themaster1]

green mask is generally a bad sign, a dll is missing or something

The green effect might be your copy of the FastLineDarken script. A fix was posted after the original appeared, so you might have the older version. Use the version of FastLineDarken shown below. Fixed version was posted here: http://forum.doom9.org/showthread.php?p=616362#post616362 . The fix in the new version is highlighted in red below:

function FastLineDarken( clip c, int "strength", int "luma_cap", int "threshold", int "thinning") {
    str = string(default(strength, 48) /128.)
    lum = string(default(luma_cap, 191))
    thr = string(default(threshold, 4))
    thinning = default(thinning,24)
    thn = string(thinning /16.)
    exin=c.expand().inpand()
    diff = yv12lutxy(c,exin,yexpr="y "+lum+" < y "+lum+" ? x "+thr+" + > x y "\
        +lum+" < y "+lum+" ? - 0 ? 127 +",uexpr="x",vexpr="x",u=2, v=2)
    linemask = yv12lut(diff.inpand(),"x 127 - "+thn+" * 255 +")\
        .yv12convolution("1 1 1","1 1 1",y=3,u=0,v=0)
    thick = yv12lutxy(c, exin, yexpr="y "+lum+" < y "+lum+" ? x "+thr+" + > x y "\
        +lum+" < y "+lum+" ? - 0 ? "+str+" * x +",uexpr="x",vexpr="x",u=2, v=2)
    thin = yv12lutxy(c.expand(),diff,yexpr="x y 127 - "+str+" 1 + * +",u=2, v=2)
    return (thinning == 0) ? thick : maskedmerge(thin,thick,linemask,y=3,u=2,v=2)

[mmbwdpnz]

well the green mask is shown a little bit, then it goes away and turns grey and purple, and then it turns to the original color with purple on parts.
