Need help with Dirty Pair DVDs

[Jack Cox]

I just got in a couple Japanese Dirty Pair DVDs and I'm trying to work with them to make an x264 backup but I'm having problems with a weird combing problem that I just don't know how to fix. If anyone can help me I'd really appreciate it.

Here's an unprocessed sample clip: http://www.megaupload.com/?d=R5V68PVG

No ideas?

I don't see a problem with combing... what does the combing look like on your end?

:script:

[Jack Cox]

mpeg2source("clip.d2v")

is the script.

Here is what I'm talking about:

It looks like that in almost every frame with almost no exception.

mpeg2source("clip.d2v")

is the script.

That's the problem right there. You have to perform IVTC on the clip to reverse the telecine process:

Try this script on your source; it'll get rid of the combing and ensure the colors are correct in the final video.

MPEG2Source("/FULL/PATH/TO/D2V/FILE",info=3).ColorMatrix(interlaced=true,hints=true)

TFM(d2v="/FULL/PATH/TO/D2V/FILE")
TDecimate(mode=1)

You can download the needed filters below. Just unzip them into your AVISynth plugins folder (usually "C:\Program Files\AviSynth 2.5\plugins") and you'll be good to go.

Good luck!

Sorry I pasted the script wrong. I am doing an IVTC with TIVTC already, add tfm(mode=3) and tdecimate(mode=1) to what I posted. I appreciate the advice but it doesn't fix the problem and if you'd actually download the clip I posted you'd notice that. Not trying to sound ungrateful, but it'd help alot more if you'd download the source clip to actually look at what I'm talking about (would have saved us the effort of this needless exchange).

I downloaded and checked the clip earlier, but didn't notice the aliasing until you pointed it out. A really fast, cheapo antialiasing could go like:

aa=BilinearResize(width,height*2).LanczosResize(width,height)
interleave(aa.selecteven,last.selectodd)

But once you take care of the even frames' killer aliasing, the odd frames' shows up more, plus it softens the picture some. If you do it to all frames, then it still looks worse on the even ones...

Working something up with eedi2/sangnom is problematic because overlays, like the japanese text in the intro, are unaliased and adversely affected by removing a field. It's also much slower for very little gain.

There are also differences in the line weights of the even/odd frames. It's almost as if the video has to be processed separately in each set to match them back up.

Try also width*2 in the formula above, there might be some difference.

Hmm, okay so its just an aliasing problem. Ugh. I just don't get why so many recent anime that get HD remasters (such as this) have this aliasing problem. I would think that by this point in time for DVD that such things like this would be a thing of the past (that or why this wasn't even recognized during some QC process before the discs were pressed). Well thanks for the help foxyshadis.

You can send it back and complain. In fact, you can write to the publisher, distributor, and even authoring house if you can find them in the credits. If it's 4kids it's probably a lost cause, butchering is a great sport to them, but the others might listen.

Hmmm, hows this (http://www.megaupload.com/?d=D9ASUWH0).

I don't know Japanese so it would be rather hard to complain to Bandai Visual about it. Plus I don't think much would come of it and aliasing aside it looks many times better than the US version which looks it's from fieldblended masters. Oh well...
