I guess that we don't need to deinterlace when encoding KDVD's since they are encoded in MPEG2? But what if I have a hybrid DVD, with both NTSCFilm and "pure" NTSC? Another thing, what max. and min. bitrate values should I use for the encode? Can I use CQMatic for KDVD's as well?
A lot of questions, but I've never tried encoding a KDVD before.

EDITo I encode the movie in 16:9 or 4:3 with TMPGEnc?

You don't need to deinterlace, and you'll get a much smoother picture by not doing that. The problem is most filters are written to deal with progressive content, so you have to use a trick to get stuff working.
You can use Telecide from Decomb Package to deal with hybrid matherial.
No sure if you can use CQMatic, but you can use my KDVD with CCE tutorial (a sticky in the top of the KDVD forum). It seems that CQMatic will add support to KDVDs later, not sure about this.
If the source is 16:9, you can encode at 16:9. You can also encode at 4:3 and gain compressability, if you plan to watch on a 4:3 TV, addind black borders. And if it's 4:3 (full screen), you have no other choice but 4:3.

I make miniDVD's with KDVD full to 2 CD's. At present, I use the following avs:

LoadPlugin("c:\video\dlls\MPEG2DEC.dll")
LoadPlugin("c:\video\dlls\sampler.dll")
LoadPlugin("c:\video\dlls\decomblegacy.dll")
LoadPlugin("c:\video\dlls\dustv5.dll")
LoadPlugin("c:\video\dlls\legalclip.dll")
LoadPlugin("c:\video\dlls\unfilter.dll")
LoadPlugin("c:\video\dlls\fluxsmooth.dll")
LoadPlugin("c:\video\dlls\GripFit_preview.dll")
LoadPlugin("c:\video\dlls\STMedianFilter.dll")


MPEG2Source("d:\sol\sol.d2v")

telecide()
decimate()
LegalClip()
unfilter(50,50)
GripCrop( 720,480 )
GripSize(resizer="BicubicResize")
STMedianFilter(8, 32, 0, 0, 8, 32)
temporalsmoother(1,2)
mergechroma(blur(1.50))
mergeluma(blur(0.1))
GripBorders()
LetterBox(16, 16, 16, 16)
LegalClip()

#Sampler(length=24)
##MPEG size = ((Total frames/MovieTimeInMinutes)/24) * MPEG sample file size ##

I output from DVD2AVI without forcefilm.

Using TMPGEnc

1. What changes should I make to avs to not deinterlace?
2. What changes should I make to TMPGEnc settings?

Nicksteel,

If your dealing if telecined content (movies and some TV shows), you should do IVTC, and looking at your script, seems to be what you are dealing, and you are already using telecide to IVTC.
But if you are dealing with truly interlaced content (sports, TV news, music presentations...) then you should not deinterlace. Then you would have to remove your deinterlacer from the script (fielddeinterlace, tomsmocomp or something like that) , change in Tmpgenc to 29.97, use the video source type interlaced and set the field order as the same as the source.

FieldDeinterlace(blend=true)
works fine for me. I used it on "2001: A Space Odyssey" (KSVCD 704x576, 2 CDs, Audio 352 kbps) and it looked VERY good. There's not this strange flickering some deinterlacing filters give you..

EDIT: This filter is contained in Decomb-Package, just like Telecide()

new_bee,

2001:A Space Odissey is a movie, and being a movie, probably can be much better handled doing InVerse TeleCine. This way you can recover the original progressive frames.
Any Deinterlacing method will give or wired movements or blured images, simply because there's no way to do a perfect deinterlacing. You simply don't have the temporal information anymore. But some time ago I tested some deinterlacers and I liked most FieldDeinterlace...
Did you try Telecide() with this movie? Or maybe Telecide especifying the right guide parameter for PAL?
Just compare the encoded version with the original one, you will see how fast movements probably got wired....

PS:It seems that DVD2AVI can already do this using the option Force Film, I haven't tested:

Yes, I tried Telecide and I didn't like that result

I don't get wired movements. Strange, isn't it? Maybe it's because 2001 is such a slow-mo movie

PS: My CCE suddenly stopped freaking and works perfectly now

EDIT: You say Inverse Telecine, isn't this only for 3:2 NTSC pulldown?

Well, I am not a PAL guy so I don't know a lot about this. But PAL Stuff is also telecined, read here:

Thx for the link!

Yes, PAL is telecined, but not inverse. That's for 29 -> 24 fps conversions.

Just an update: it seems that for not "heavily interlaced stuff", I mean like home movies that shake all the time and musicals with lots of pan and scans, deinterlacing doesn't look that bad. Depending on how picky you are, you can live with it. I deinterlaced a Abba DVD and the results were good, there was some ghosting but acceptable.

Ok.. I got one for the experts...

I know that using my DV cam for shooting XMas morning is filmed at 29.97fps and is therefor interlaced. My cam has analog input. Let's say I capture my forvorite movie from VHS (that is not on DVD yet) to X # of DV tapes. Now since this was capped on the DV cam is this now truly interlaced or can IVTC be used AND maintain audio sync (after pulldown is applied)?

By the by, this is for KDVD, of course...

Since your captured material is interlaced, but is also telecined, you should be able to apply IVTC
