Deinterlacing for South Park?

[Noah]

I'm trying to get a good deinterlacing script down for South Park episodes. They're all 29.97 fps pure interlaced video, so it should be easy enough, but I'm getting a lot of aliasing with everything I've tried so far.

I've had the best luck with:

FieldDeinterlace(full=false,blend=false)
or
KernelDeint(order=1)

Those still produce a lot of aliasing in deinterlaced sections of the frame, but are better than just FieldDeinterlace(blend=false) (the default in DVD Rebuilder), which results in aliasing on diagonal lines of every frame.

Any suggestions?

to an IVTC using telecide & decimate

Try sangnom() or tomsmocomp() ( with or without search effort ). Both have a good upsampling algorithm ( edge directed ), hence they should / will reduce the aliasing.

You'll find sangnom() here (http://atlas2.tgv.net/~media-video/forum2/download.php?id=244) ( some peoples have problems with this url, if it doesn't work, try here (http://jourdan.madism.org/~manao/) )

to an IVTC using telecide & decimateHmmm...I think you're right. I had hoped this wasn't telecined, since that makes it basically impossible to deinterlace and encode in Rebuilder, but the after telecide/decimate it looks just about perfect.

I think I'll try sangnom() and tomsmocomp() just to see if they can clear up the aliasing. It would be nice to be able to use Rebuilder.

Nothing's ever easy, is it? ;)
