Hi guys.

I'm making this post on behalf of an encoder, because we need a little help with an encoding problem (please bear in mind I'm not a encoder, but I'm a farily technical guy so speak freely :P)

The problem is with the Japanese DVD of the Anime Iriya no Sora USO No Natsu, we have a problem with the "lines" of the drawings... they're not straight lines...more like a chainsaw, lol

I believe it's a deinterlacing problem... but we're open to sugestions, of course.

I've upload a sample of the encoded file (with the problem)

Sample 1 (http://rapidshare.com/files/177233586/_FAN___Iriya_no_Sora_OVA__01___CQ__007.mp4.html)

and another sample
Sample 2 (http://www.megaupload.com/pt/?d=2SRBW28X)

The encoder tried 3 different settings:
1) tfm(order=1).tdecimate(mode=1,hybrid=3)

2) TFM(order=1,mode=2,pp=5)

3) tfm (slow=2)
tdecimate (mode=1)

But none seem to take over the issue...

I've also uploaded small ISO files (created with DVDShrink, no compression) of clips of the DVD

The opening of the anime (http://www.sendspace.com/file/92ighx)

Random time (http://www.sendspace.com/file/3bmvwe)

Any help would be apreciated :)

I think what you have here, at least from the opening credits, is a hybrid source.
animeivtc(mode=5, aa=0)
This means you'll have to do a VFR encode. If you see that the lines still are there, then what you might have is dot crawl.

Thanks for the tip :) My encoder friend is making another attempt. He told me he was having trouble with AnimeIVTC, but that's a problem we'll figure out :)

I'll be back with results when I have them.

Anyway, thanks for your time :)

Which kind of problems? A release is coming quite soon and I'd like to get rid of the many issues/add some improvements.

edit : I just had a look at your clip. It clearly has a 3:2 pattern and running it through vfr decimation returns 100% film, so what you have is simply hard telecine. A solution to the "chainsaw" edges is using external interpolation + deinterlacing since field matchers can have a hard time when used alone.

i=mpeg2source("d2v")
i.tfm(slow=2,clip2=i.tdeint(2,edeint=i.nnedi(-2),emask=i.tmm(1)))
tdecimate()

which is the same as
animeivtc(mode=1,killcomb=0)

Sorry, I didn't specify the problems about animeIVTC, actually I think it was just a problem setting up animeivtc, which is quite easy (I've done it my self)... his computer acts a bit weird sometimes, lol

Anyway, thanks for the tip I will forward that information :D
Many many thanks :D
