Regarding these cover:

http://www.roderidder.be/Scara/SW-54.jpg

Now, is there actually an online-shop that sells silver inkjet-paper big enough for these covers? It has to have at least "legal"-format I guess, because there's no other size since "letter" (which is to small) that I know of. In one of the very first posts in this thread the creator of these covers, Scara, got quoted (from wherever) saying something about printing these on silver-paper. I've got some silver-paper at a German online-shop in "A4"-size (which is almost the same size as the American "letter" format), but again, these are too short for 7-disc AlphaPAKs.

Anybody?

@Zion:
It's strange that the MaskTool-filter doesn't seem to work... after all the yv12lutxy-thingy is contained in it... maybe a typo in the path? I happen to put typos into my scripts all the time, wondering why they don't work.

Oh, and could I get another one of your captures to play with? A brighter one? The Vader/Leia-scene would do fine again...

@Karyudo:
I think you've gone a little too far with the sharpening of the face-image... it's got some "painted" looking areas. (especially in the out-of-focus areas)

This is the way to make it work:

First of all copy and paste the LimitedSharpen script in to a new, empty text-file. Save this as limitedsharpen.avsi into your AviSynth plugin-folder. The missing function "yv12lutxy()" is contained in the MaskTools plugin, which should be unzipped into a directory other than your plugin-folder (just create a subdirectory). Then, as seen in the script I posted, you'll load the MaskTools plugin, pointing to the correct location, of course.

EDIT: Karyudo beat me about the first part of the answer

@Karyudo:
Here's the link to the Doom9 forum-thread containing the LimitedSharpen-function.

Normally PAL doesn't need IVTC, since PAL material is usually created by speeding up 24p-film material (actually 23.976p) to 25p, instead of telecining it (which is only necessary to bring 24p to 60i-NTSC). BUT sometimes there's PAL material that wasn't created from the original 24p source, but from the telecined 60i crap... and this is usually done very crudely, with fields being blended together and other nasty stuff. You should really try Doom9 and its forums regarding this stuff. Especially the AviSynth Usage forum is pretty cool.

By the way, now that MeBeJedi has posted some of his captures, I have played around with them a little bit, and I've got an idea:

MeBe has captured his footage at quite a low contrast... so blacks are not black but dark-grey, whereas whites aren't completely white either. Now, using my old ghost removal method (basically using the Exorcist filter, or AviSynth's pendant Ghostbuster) works without any of the problematic artifacts, because they resulted from blacks already being perfect black and whites being perfect white in the captures (as it was the case with the clip I got from you).

There's no point in throwing out buckets of visual information to "cover up" a few glitches (which, again, is why I am using Combustion 3, and also why I intend to master both versions.)


The player IS throwing away some resolution, that's true... but the resolution that gets lost was added by US when scaling up the image to be anamorph. It's the same as if you would be scaling the image up and down again in VirtualDub... there's no notable change in quality here.

Oops, my mistake... I meant "SangNom for AviSynth"... it was late. I've tried to do as much processing in AviSynth as possible... this spares me some uneccessary further inbetween steps. I didn't use the antialiasing-script from Doom9... I've started with it, but it was slow as hell. So I've tried using SangNom alone, and that's the result you see above. Here's the script:

    LoadPlugin("E:\Programme\AviSynth2\plugins\bak\MaskTools.dll")

    v1=AviSource("e:\zion_rec.avi").SeparateFields.SelectEvery(10,0,1,2,3,4,5,6,9).Weave.AssumeFPS(23.976)
    v2=AviSource("e:\zion_rec.avi").SeparateFields.SelectEvery(10,0,1,2,3,4,5,6,9).Weave.AssumeFPS(23.976).crop(4,0,0,0).AddBorders(0,0,4,0, color=$FFFFFF).blur(.5)

    v3 = overlay(v1,v2, opacity=0.2, mode="Darken")

    v4 = v3.Crop(0,102,-0,-102).Lanczos4Resize(720,600)

    v4a=v4.SangNom(order=0)
    v4b=v4.SangNom(order=1)

    v5 = v4a.ConvertToYV12.overlay(v4b, opacity=0.5).LimitedSharpen
    v6 = v5.Levels(0,1.236,224,0,255).Lanczos4Resize(720,376).AddBorders(0,52,0,52)

    Return v6


The steps until v3 are necessary for my "bright ghost"-removal, so the script gets a little big there (strange enough the Telecide filter, which worked well in the past, now gets me one double frame every 5 or so frames... that's why I've returned to my manual IVTC-method using SelectEvery).

v4 is used to cut off the black bars from the capture, and to provide some extra resolution for SangNom to work with. Now, you can see that I've used two instances of SangNom, resulting in v4a and v4b. The reason is, SangNom was developed as a deinterlacing filter, so it is used to work with "bobbing" footage (footage, that is deinterlaced, and therefore alternates, "bobs", between the two fields), so it needs some info on the footage's field-order. In this case though there is no field order, since the jaggy lines are not resulting from deinterlacing anything.

So, we'll use SangNom for both possible field-orders (v4a and v4b), and blend the two results in v5. I am also adding the LimitedSharpen script (which I might post or link to on request), to compensate for any blurring caused by SangNom, and since that script needs the MaskTools-package, I've loaded it in the first line (it causes some trouble when being autoloaded from the AviSynth plugin directory, so you have to put it in some other directory and load it manually).

v6 doesn't do too much... some little contrast correction (I guess this could be left out when you do the color correction in Premiere afterwards), the image get's resized to the anamorphic size, and the black bars are added to give the image the full resolution of 720x480.

I hope this helps.

Now that the ghost-removal has hit its (current) limits, I tried myself on improving the quality in some other areas. One of the visible artifacts in the image were jaggy diagonal lines, which I tried to smooth out using the SangNom deinterlace filter for AviSynth. Its actual purpose is to make deinterlaced material progressive, meaning the jaggy lines resulting from deinterlacing an interlaced source being smoothed to improve resolution. Here are some captures I took from Gonzo's set, comparing its original state as taken from the DVD with the optimized version, using the SangNom filter (and the LimitedSharpen filter, to compensate for any blurring resulting from it):

http://www.scummbar.com/mi2/temp/opt0.gifhttp://www.scummbar.com/mi2/temp/opt1.gifhttp://www.scummbar.com/mi2/temp/opt2.gif

And here's an MPEG (ca. 10MB) showing Zion's capture switching between its raw version and my optimized version (ghost-removal, jaggy-smoothing, contrast-correction).

The result is already pretty nice, but there are some situations, where SangNom causes artifacts to occure, like detail areas, where the filter can't differenciate between jaggies and detail. Some examples are the letters from the opening crawl as they get smaller, and some of the space-ship details. But judging from the few miutes of film I've tested this on, these artifacts might be negligible, regarding the quality boost in most other scenes. Maybe it's even an option to combine filtered and unfiltered scenes in editing... though I would understand if Zion doesn't want to do this

So, are we now calling him that OFFICIALLY?

Oh, and the benefit from making the anamorphic is a higher quality... I know, this has been denied by many people, but you should consider that any possible compression artifacts get squeezed together (or only stretched horizontally, as opposed to a zoomed letterboxed image), and become teeny-tiny... well, at least less visible.

Yeah, I haven't found those anywhere... and I REALLY would like to have them (especially the box-covers... I don't need the single-case covers). Actually what I want even more is a "clean" version of them, meaning most of the text gone, for me to customize it towards my needs). But having those versions would be great already.

Something new on the IVTC-issue:

Get the DeComb-package, and then you can just use the Telecide(1) command in AviSynth. So you no longer need to separate and weave the fields manually. In the script this would be enough:
    AviSource("e:\zion.avi").ConvertToYUY2.GuavaComb(mode="NTSC").Telecide(1)

    AssumeFPS(23.976)

    return last
I don't know if the AssumeFPS command is really necessary, but without it the resulting clip only has a framerate of 23.970 ... which, I think, wouldn't work when creating a DVD out of it. But you should try it, and check, if the audio is in sync.

Oh no... I have to disappoint you guys again... my "new" ghostbuster-method wouldn't work either. I have just tried it on some other pics, and this is the problem:

http://www.scummbar.com/mi2/temp/anhx.jpg

The new method only takes care of ghosts being cast FROM darker areas ONTO brighter areas, resulting in even brighter halos.

It does NOT take care of darker halos being cast FROM brighter areas ONTO darker areas... as you can see the bright twin-suns are casting dark ghosts onto the sky... unacceptable. Maybe my old method is better? No... well... the bright halos in the dark areas (check the stormtrooper-arm above) aren't acceptable either... arrgh!!!

I think the detail-differences are just caused by the two images not being the same frames in the movie. As you can see, 3PO isn't as close to the camera as in the upper image, and so I guess reflection on R2's blue parts occures in this later (or earlier) frame.

But it's true, the images are still a little over-saturated. This is especially visible on these screenshots:

http://www.aptirrelevance.com/videoprojects/images/ANH.jer.dvdi.04.jpg

They look kinda sunburned... but with a little less saturation your color-correction looks just great.

I am frameserving that script into VirtualDub where I crop and resize the image. And other than that sharpening-approach I showed in my "filter overview" a few posts ago (through upscaling, Xsharpen and downsizing again) I am not doing anything else in VirtualDub. Although, maybe that sharpening isn't necessary. The downside of my new ghostbuster is that there's a little more noise left than with my old method. But again, I don't mind the noise... it makes the image look more natural.

Oh, and my IVTC-method (using the SelectEvery-command) only works with your sample (or any clip that starts on the same frame of the pulldown-cycle). I guess the Telecide-filter for AviSynth would yield the same result AND it would recognize the pulldown-cycle correctly.
