Deinterlacing

avisynth.nl states the following:

For MPEG files you could use DirectShowSource, so you would write:
DirectShowSource("c:\folder\myclip.mpg", fps=25)

But it would be better to use DGDecode for importing MPEG files.

I'm working with MPEG-2 files (DVDs), so should I use either of those recommendations?

DGDecode is superior. DirectShowSource is not frame accurate (how inaccurate it is depends on the DirectShow components you have installed). Use DgIndex to build an index file then use:

Mpeg2Source("filename.d2v")

to open the MPG file. Mpeg2Source() also has deblocking and deringing options, and the ability to pass field order information.

Someone just made the following post on another forum. Input?

However, if the DVD is ripped then the teeth (as you call them) or combing becomes part of the re-encoded picture. The player does not know it is interlaced and then shows the 'teeth'. They looks worse as you scale the picture up. It can only then be removed through various filtering or interpolation methods. You will lose some quality.

But if you de-interlace during the ripping then you get a better cleaner result.

My advice? View the original DVDs or re-rip your DVDs with de-interlacing turned on.

Sorry to be so long-winded but I hope that helps.

The guy doesn't know what he's talking about. There's so much wrong with what he says that you'd best pretend you never read it.

That's exactly what I thought. This is the forum for The Velvet Underground, by the way. I wasn't getting second opinions on another video forum. I'm content with the great information provided here.

The de-interlacing stuff gave me a laugh. xvid1's posts on the Xvid4PSP page (posts 5, 6, 7 and 8) are better though.
