croppy interlacing

[homer123]

first: hi to all ;)

i'm new here and i have a very big problem with an anime that i sure know that many people know here.

before i post my problem, i have to give some information about this anime to you.

Name: Dragon Ball Z

Frametype: Interlaced

DVD-Type: DVD-9

DVD-Format: NTSC

Episodes: 9 Episodes each Disc

VOB-sizes: ca 950 MB each episode

Lengh: ca 25 minutes each Episode

Birate: ca 5000kbps

ok i think that should be enough for the beginning.
Here are some problems i that i have:

Problem 1

i have used ITVC for the anime because it would be impossible to make a good encode (=29.97fps) with an old anime of year 1992.
So, after using the IVTC with the following script;

Telecide(order=1,guide=1)Decimate()

there are still some "traces" of interlaced frames that i dont know how to fix them. I tried everything i could but there's just no way how to fix it.

Here's a pic i have made.

Problem 2

As all of you know, there is a debug on the filter mpeg2source included. So have used that and made the following script:

MPEG2Source("E:\DRAGON_BOX_1_8_SCN\VIDEO_TS\01.d2v",cpu=6)

but when i saw this croppy thing,

then i knew there's something wrong but i dont know what it is.

ok guys those two gapps are my main objective to fill ;)

i hope, that anyone here can help me. You're my last hope :)
and before i forget...here's my non-finished AVS-script.

MPEG2Source("E:\DRAGON_BOX_1_8_SCN\VIDEO_TS\01.d2v",cpu=6)
Tweak(sat=1.5,bright=15)
Convolution3D(1, 8, 16, 8, 8, 2.8, 0)
Telecide(1,guide=1)Decimate()

Thx in advance

provide an unprocessed sample VOB snipplet.

MPEG2Source("E:\DRAGON_BOX_1_8_SCN\VIDEO_TS\01.d2v",cpu=6)
Tweak(sat=1.5,bright=15)
Convolution3D(1, 8, 16, 8, 8, 2.8, 0)
Telecide(1,guide=1)Decimate()
Put Telecide and Decimate before Tweak and Convolution3D.

Since your material is interlaced, put ipp=true in mpeg2source since you are using cpu=6.

[scharfis_brain]

Since your material is interlaced, put ipp=true in mpeg2source since you are using cpu=6.

setting iPP=true is never necessary, cause mpeg2source() relies on the Progressive_Frame flag to judge whether a frame is encoded interlaced or progressive.

leaving iPP undefined (and thus the mode decision being automatic) is most flexible and is the best solution quality wise in general.

I would have said it's a chroma issue that would be solved with a colorspace conversion, but since the source is a DVD I don't know what it is. Anyway, for animated content I highly recommend TIVTC (http://forum.doom9.org/showpost.php?p=746511&postcount=428) over DeComb. Use the following calls:

TFM(d2v="X:\wherever\YourD2V.d2v",mode=6,PP=7,slow=2,mChroma=true,chroma=true)
TDecimate(mode=1)

if your source doesn't have heavy rainbowing.

@Chainmax

Thx for fixing problem 2 its looking better now^^

but nothing helped on problem 1. So i have uploaded here for you all the vob file for problem 1.

From looking at the picture it almost looks like dot crawl.
If it is, DeDot (http://nullinfo.s21.xrea.com/#DeDot_YV12) should take care of it.
Just put it in your plugin folder and add the line DeDot() to your script.

[Chainmax]

If you do, remember to use it before IVTC.

another thing, cpu=6 can give unstable results - it'll deblock/dering based on per-frame quantizers, which will tend to oversmooth b-frames and make texture pump in and out in a way that isn't in the original encode.

try leave it at the default (cpu=0) and use a deblocker further along the chain. blindpp with quant set to 8 or so, cpu=4 should catch most of the blocking. for the really heavy blocking there's not much that can be done (except get a better source. is this the vanilla release or the remastered one with the stupid red-noise intros?).

IMHO this show isn't worth the effort. there'll just be another full re-release in 2 month's time... if it weren't for DBZ, funimation would have gone under years ago :)

[homer123]

well i dont know what kind of release it is but i have blue boxes that i can import from japan. I paied a lot of money (ca $70). If i would have a broathband connection i would send you the whole episode:P

Well i dont like funimation, they make just everything worse. (some dirty white stuff comes after changing the scenes)

i have heard of a group, that is using (i hope) the same source as i do. And they know how to fix it. i have asked them how to fix my problem 1 but all what i have recieved is to go at doom9-forum....

well anyway here (http://www.cybercombatclub.com/catalog/index.php?cPath=28) are some pics of the dvd sources.
i have the boxes 1 & 2

by the way: the Dedot filter is not at the avisynth homepage (external filters)

[Mug Funky]

if it's filters you want, best search this forum - they're mostly released here (or find their way here when they aren't).

[edit]

btw, dirty white stuff on scene cuts sounds to me like film splicing tape. that's probably on the japanese one too, unless it's a cut that's been made by funimation. DeSpot might handle it okay, or even some custom script that replaces scenechanges with dupes of adjacent frames.

[homer123]

i have found it already :)

edit: well i dont care anyway, i like the ORIGINAL not the edited stuff ;)

by the way, i have used Dedot and blindpp. its only a liiiiiittle bit better.
i think that the telecde must have made it...

edit 2:

guys, i just have fixed the problem. You wont believe me what i have done for that.

i have used the internal virtualdub filters:

resize (precise Bilinear)
chroma smoother (mode 4:1:1)
smoother (g:5000)
warp sharp (depth: 50, blur: 1x)
brightness 12%

and thats the AVS-script that i want to thank you^^

MPEG2Source("E:\DRAGON_BOX_1_8_SCN\VIDEO_TS\01.d2v",cpu=4,cpu2="xxxxoo")
TFM(d2v="E:\DRAGON_BOX_1_8_SCN\VIDEO_TS\01.d2v",mode=6,PP=7,slow=2,mChroma=true,chroma=true)
tdecimate(mode=1)
BlindPP(quant=8, cpu2="xxxxoo")
Tweak(sat=1.25)

you see i have changed a few things^^

if you have any suggestions just write them here.

@admins:

please do not close this tread, it could be possible that some changes can happen. BIG THX in advance.

[scharfis_brain]

problem 1 is no problem at all!

it is just the chroma subsampling is getting visible due to a source with a very good detail definition.
Every attempt to filter this out will yield into a heavy chroma blur.

The only thing you can without any losses is to use fddshow as decoder and enable high quality rgb conversion in its output settings.

[homer123]

well i have now a problem with fddshow

after creating an AVI file, opening in virtualdubmod, compressing with XVID, my player cant play it properly :/

does anyone know what to do?

[scharfis_brain]

what means 'not properly' ?

I am not a diviner

[homer123]

german = sauber bzw. fluessig ;)

[scharfis_brain]

doesn't explain anything.
please elaborate!

[homer123]

i mean my wmplayer stopps for 2 or 3 seconds playing it, then it continues playing it..

playing,stopping,playing,stopping, etc

[scharfis_brain]

do not use wmplayer.
disable yv12 and i420 in ffdshows output config.
