Some newbie questions on DVD ripping

[e-Pawel]

Hy,

here are my questions:

- What do ripping programms exactly do? Into which file type do they convert the mpeg-2 footage? What's the convenience of using such apps? I mean, you can copy the vob-files onto your hdd and convert them directly with VirtualDubMod.
- Are DVD mpeg-2 video files basically interlaced? Or are some DVD's progressive too?
- What's your favourite filter to deinterlace interlaced footage?

Bye for now, Pawel

-Ripping programs find the CSS key for the dvd and then copy the decrypted content to your harddrive. They also try to work around other protections such as ARccOS. If you would just copy them you would still have to use another app to decrypt them before you could do any further processing. Programs like DVDDecrypter also have the advantage that you can select which audio tracks you want to copy, which reduces the size of the image on your harddrive, and they also let you select titles, so you can for instance choose a single episode of a TV-Series.

-From personal experiance most DVDs from Europe are progressive. I have some older DVDs that are interlaced and some that are mostly progressive with some interlaced parts (Leon). The US DVDs I own are all telecined.

-There is software which detects good ways for deinterlacing for instance the avisynth script generator in megui. Personally I like tdeint and tivtc for deinterlacing and ivtcing.

Also please read the forum rules. (http://forum.doom9.org/forum-rules.htm) You are not really allowed to ask what's best (rule 12).

But which file type/codec does the encrpyting application use to save the ripped footage?

It's strange... I checked some of my DVDs (e.g. Shrek 2) and GSpot showed that all of them are interlaced. However in most cases you don't really see any interlace artifacts.

I am a NEWBIE X10. I cannot figure out what is PARSE VTSM RUNTIME EXCEPTION means? I downloaded Pgcedit and I think it help with Navigation Structure but then I got the above message. I am trying to rip SAW3. Can anyone direct me to where I can get a good tutorial w/Doom? By the way, THANK YOU very much for the guides, etc..Doom, they are a real help, but as I said I am technically challenged so some of it goes over my head, alot of it actually..Thanks :D

The fact that you are so confused with your terminology shows that you've made little attempt to read and research the basics on your own. When you rip a disk to your hard drive, you are decrypting the CSS protection in order to save the files unchanged. When you compress them to another format, for example .AVI, you are re-encoding the files. When you select a program to re-encode, you either select one for an intended purpose or you select the type of output you need within that application.

Thanks :) Acutally I knew what re-encoding means and how to convert DVD -> Xvid/DivX but since I haven't used such a tool yet and you can open .vob files with VirtualDubMod offhand I couldn't figure out what such a ripping application actually does ;)

But if it the output is an ordinary MPEG-2 file how is it possible to open and re-encode it with the standard version of VDub?

Hi-

But if it the output is an ordinary MPEG-2 file how is it possible to open and re-encode it with the standard version of VDub?

It's not. It doesn't support MPEG-2. You use VDubMod or VDubMPEG-2 if you want to open Vobs or MPEG-2 files. If you want to convert your movie to AVI, I might suggest decrypting with DVDDecrypter set for IFO Mode, and then using AutoGK for the job. It's not a good idea to encode the vobs directly in VDubMod. Much better (and faster, with better quality) would be to use AviSynth to frameserve, something AutoGK does very well.

terri613-

Your question is not even remotely related to the subject of this post. Better would be to start your own thread in the Decrypting Forum. Anyway, Saw3 can only be decrypted properly (as far as I know at this point) using the latest version of RipIt4Me (together with DVDDecrypter and FixVTS). There's a good guide for its use at the RipIt4Me site.

thank you..as much as I appreciate this Forum, I consistently see rudeness when someone new is confused. Is that how u treat Newbies? I thought this particular Thread was for Question's regarding Ripping DVD's, so I am confused as to how my question didn't fit that thread? I am trying and reading, as well as trial and error, and for someone new to this, all these questions/forums can be confusing. AS for Ripping SAW3 with RIPIT4me, I did that, WITh the updated version, and I cleaned it, I just can't burn it. I am going to post a question in Decrypting, which I gather is not the same thing as ripping? Thanks anyway.

Hehe, you thought that was rude? You ought to see me when I'm really rude. OK, your question was remotely related to the thread subject. But the thread is a general one about decrypting and deinterlacing, and your question references a specific DVD. I'd say they were 2 pretty different things.

I did that, WITh the updated version, and I cleaned it, I just can't burn it.

Is this a different question than your first one? Is it related to your PARSE VTSM RUNTIME EXCEPTION problem? Did you get that in RipIt4Me? In order to help, we need detailed information. You didn't even tell us how you decrypted the DVD in your first post. Your 2nd post seems to imply that RipIt4Me did the job, but now you're having trouble burning it to disc? Forgive me, but that sounds like a totally unrelated problem. Or maybe I'm completely misunderstanding.

Edit: Now I see you created a new thread about your problem. Good one. Looks like setarip_old will get you straightened out.

From personal experiance most DVDs from Europe are progressive. I have some older DVDs that are interlaced and some that are mostly progressive with some interlaced parts (Leon). The US DVDs I own are all telecined.


Now I'm really confused :(

The DVD I checked is Shrek 2:

GSpot shows that it's interlaced: http://img255.imageshack.us/img255/3349/shrek2gspotqi1.th.jpg (http://img255.imageshack.us/my.php?image=shrek2gspotqi1.jpg)

While DGIndex shows that it's progressive: http://img245.imageshack.us/img245/3541/shrek2dgindexdi5.th.jpg (http://img245.imageshack.us/my.php?image=shrek2dgindexdi5.jpg)

What is correct?

[cmw]

Most likely DGIndex is correct, but you could use MeGUIS AviSynth Script Generator to be sure, it does a very thourogh job at detecting interlaced material.

Vor allem weil wie schon weiter oben gesagt wurde dass die meisten europäischen DVDs progressive sind. Nur billige Anime-DVDs oder gelegentlich Musik-DVDs sind interlaced. Shrek2 mit extremer Sicherheit nicht.

And don't let modest rudeness scare you off, at least the powers here don't act so amusingly rediculous on that sort of question as compared to the gleitz forum. ;)

What is correct? Was this another case where field order correction kicked in when you made the D2V?
