Unusual interlacing lines.

[cheeks]

Hiya folks,

I've just encoded an NTSC DVD via DVD2SVCD to (wait for it) SVCD with the usual commendable results - only I seem to have gotten myself some not-so-commendable interlacing lines or artifacts that I haven't encountered before (but hey, I'm no long-standing veteran).

To illustrate what I'm talking about, I've posted a capture here:

And my DVD2SVCD log of an encoded sample from the same source here:

I've tried activating IVTC but I just get a bunch of errors (couldn't create .d2v file, incompatible frame rate...).

So, I'm at a loss as of what to do next!

Any thoughts?

Thankyou.

Well you have an interlaced source. Assuming you want to watch it on a tv, just keep it interlaced. Select "Off" in the Dvd2avi tab and no deinterlacing or keep interlaced in the conversion tab. You may want to set up interlaced resize for this use. Paste this into your avisynth.ini if using new version or dvd2svcd.ini for older versions.

[AVISYNTH_InterlacedResize]
0=LoadPlugin(!SimpleResize.dll)
1=ConvertToYUY2().InterlacedResize(^TargetWidth,^TargetHeight)
2=AddBorders(0,^BorderTop,0,^BorderBottom)
!SimpleResize.dll=C:\Program Files\DVD2SVCD\Avisynth2.5 Plugins\SimpleResize\SimpleResize.dll

Hey DDog, thanks for replying.

I do intend on watching this on my TV so I have been keeping it interlaced during the encoding. I have only a basic understanding of interlacing and telecining and so forth.

The capture I included is a bit deceptive since it doesn't really accurately portray how things look on my TV. It seems as if the interlacing lines are not properly aligning with the scanlines of the television, kinda like watching an interlaced source on a progressive monitor.

I can only imagine that, in the process of downconverting the 16:9 anamorphic source to a 4:3 SVCD, the image is somehow not decombing (?) properly. I don't really understand how this works, however.

Anyhow, it seems as though activating 'smart deinterlacing' addresses the problem. Thanks for your assistance.
