NTSC Pure Interlaced guides?

[SatoriGFX]

I am trying to back up some DVD's which are NTSC Pure Interlaced with mixed results. I have searched this forum and the advanced forum for information and have only become more confused. There are a million suggestions, many of which contradict each other. In addition, when someone suggests, for example, to use "smart deinterlace" they forget to mention what in the world you are supposed to do with the force film settings and the settings in the advanced tab on the encoder page (when using cce). Or, it's the other way around. It seems there are several ways to handle interlaced material. What I would love to see is one complete description of what options to choose on the conversion, encoder, frameserver and DVD2AVI tabs. Better yet, a chart showing all of the possible setting combinations for all of the various ways of handling interlaced material. I thought DVD2SVCD was a breeze when I was only ripping progressive material, but now that I am ripping pure interlaced material I am ready to pull my hair out.

I have successfully backed up "Following" but am having a real time with "The Devil's Backbone". Both are NTSC Pure Interlaced.

I do quite alot of interlaced material and i have found a great way. all the movies that i have done work well with these settings. If you are using the new dvd2svcd then on the conversion tab put keep interlaced, and on the encoder tab put bottom field first and on the advanced tab uncheck progressive. i do alot of martial arts movies and they are all ntsc interlaced. I have gone back to the older verion 109.3 because i am having problems with subtitles, it is skipping a few subtitles(not showing them long enough to actually read) in the new version so i can't check keep interlaced but i do the rest of the settings and it looks good. i hope this might help.

"on the conversion tab put keep interlaced"

Strange, tried that once and had problems. Leaving it set at no deinterlacing has worked in the past though.

"and on the encoder tab put bottom field first and on the advanced tab uncheck progressive."

Ok. But my DVD is reported by BitrateViewer as top field first and what about zigzag scanning order?

And what type of resize are you using?

I have finally in the past hour gotten a decent result by leaving everything at default but deactivating zigzag scanning order as well as progressive frames and using InterlacedResize. I have turned off linear quantizer as well as the noise filter. So, I am getting what I think is a good result now, but I still would like to know if I am using the best settings.

I also use bitrate veiwer and it always says top field first, i think there is a problem with it. when i encode top field first the movie jitters during action so i do bottom and it works.

i also would like to know the "best way" but for me after trial and error i have found this the best, so far.

This is what I use:

1) Make sure you use the default settings that come with D2S1.1.0b1a
2) Now on the DVD2AVI tab set to "Not Force Film" and on the conversion tab use "Smart Deinterlace"

This will make you movie as Progressive Scan material so you will be able to watch it both on TV and PC properly.

NOTE: Turning on Anti-Noise, temporal smoothness and other filters may or may not work as they sometimes result in CCE crash. But CCE crash is not so common, if CCE crashes and you are using any of these settings turn them off. That's why in the begining I said, restore defaults as they are the best.

Good Luck,

Thanks to both of you.

Amit, I will give your method a try. So, using your method, I will end up with a straight 29.97fps progressive stream (not 23.976 with pulldown)?

Could you please state your used version of DVD2SVCD and if you are using pal or ntsc. This problem keeps lingering on, and I would like to close in on it. Thanks!

I have used this method on 109.3 and the new version. I am using ntsc. i have followed other version that work but this way i seem to get better quality, less noise and of course it encodes faster since i am not using ivtc. i am keeping it interlaced and keeping the framerate at 29.97.these movies don't play good that good on the computer(has lines running through it) but i never watch my movies on the computer. I am always looking for "better" but so far this is the best i have gotten, and it looks as good as doing progressive movies with the pulldown.

It wouldn't be a bad idea just to take a small part of the movie and do tests on it. Take a chapter and do different settings till you get the results you like. The reason you see so many different ways to do interlaced movies is people have different views on what looks best. So doing a 30 minute test seems the best solution.

That's what I usually do. It's just that there seem to be so many ways to handle interlaced material. I could probably spend days encoding test chapters.

Anyhow, I will try the methods suggested and compare them to the results I got by using InterlacedResize and turning off Progressive Frames and Zigzag scanning order (seemed pretty damn good actually now that I have had a chance to sit down and watch the movie again).

Thanks.

Well as you can see sometimes you have no choice but to test it yourself. Glad you found something your eye's prefer as thats the hardest part:)

This is what I call the "Field Order Bug". It is rumored to have been fixed, but I definatly ran into it in 109b3. The author DVD2SVCD also tried to fix it and considers the 109b3 release bugfree in this regard. I am not sure however, so I would like to know when you last had problems with the auto setting? It is known that 109b3 had problems remembering the setting, and when one recovers an encode with altered settings, it would get the field order wrong.

Did you ever have a problem with 110b1a and field order on auto?.

(I am not interested in the interlace aspect, if you look for Star Trek threads, you will find plenty of dicussion on this topic, also about the elusive field order bug)

In the new version it seems to be working right, although i usually set it all up by hand. I have encoded 1 movie which dvd2svcd picked all the right settings except it took off zigzag order wich seemed to give me better quality with this checked.
