Help w/ DVD Decrypter

[Aliyah]

I am totally new to web video- audio editing and I am running into quite a few problems. I have dvd decrypter and I am trying to rip a 5 min 41 second section of one of my dance performances off of one of my performance dvds so that I can edit it (in windows movie maker or roxio) to make video clips for my web site. I was able to convert the segment to MPEG (2, I believe) that automatically plays in real player but it has no sound and I am not able to import the converted segment into windows movie maker to edit. I have been browsing through the doom9. org forum, but haven't found a thread specific/ clear enough to get me back on track. Can you please tell me what I am doing wrong? I did use the guides on videohelp.com and doom9.org, but I continue to have the aforementioned problems (ie, no sound and can't edit video).

I thank you very much for your time in advance.

Hello, and welcome to the forum.

You might -- repeat, might -- be able to get away with renaming a VOB file from .vob to .mpg. Its possible -- only possible -- that one of your encoders will be able to use it as such.

If not, and if you have a high speed connection, you might try downloading Ulead's VideoStudio 8 (30-day trial at www.ulead.com) to see if it meets your needs.For your purposes, it might be helpful, since I understand it can directly use DVD in the editing process, and can produce .wmv output suitable for use on your website. It is designed for the novice consumer, and, as such, would be a complete application that can assist you to go from DVD to the web. And, because it is a commercial product intended for consumers, it is a relatively low cost tool, at about US$100.DVD Decrypter in IFO mode can be used to demux an MPEG-2 video stream (.m2v) and the applicable audio track. The audio might be Dolby Digital (.ac3), Linear PCM (.wav), or MPEG-1 Layer II (.m2a). But I do not use Roxio, nor Windows Media Maker, and cannot give guidance on how to assemble a finished .wmv from these separate streams.

Hi,
Thanks for the rapid response. I am curious to know if I misunderstood DVD Decryptors funtions... I thought that it is something that I could use to get the files to avi (or some other easy to edit format) so that I could then edit and make clips:confused: Like I said I am totally new to this so I'll have a lot of stupid questions:)
I would also like to know why when I ripped (IFO- demux) the chapter I got video but no sound. The same thing happened when I used FlaskMpeg and WinAVI. Apparently, there is something else that I need to do or a codec that I am missing. How can I fix this?

Thank you for your time in advance.

hi and also welcome to the forum,

unfortunately you have some misunderstood dvddecrypters capabilities. all it can do is bypass the copyprotection that is present on most dvds (not your performance dvd most likely though) and copy the dvd files to your hard disk. it can also extract certain sectors of a dvd if desired (as you did).

converting the file to an editable format is the task of other programs - e.g. gordianknot (a little advanced) or autoGK (easier).

it can extract the sound from the vob files though. all you have to do is to hit the stream processing tab, check the enable stream processing checkbox, and then select the streams that you want to have demuxed. you will then end up with a mpv or m2v file (video) and an ac3 or maybe mpa/mp2 or pcm/wav file for the audio.

alternatively you can use dvd2avi to do the demuxing step on the files you already have on your hard drive.

Ohh...that explains:o
Are there any *freeware* programs out there that can do what I need?

Thanks for your time in advance.

gordianknot - freeware
autoGK - freeware
dvd2avi /dgindex - freeware
guides - free at doom9.org

Killingspree -- Aliyah wants output suitable for use on her website. As I understood it, she would like .wmv output for streaming video to the general public.

Your suggestion of using AutoGK to produce an XviD or DivX .avi file would only be an interim step. Unfortunately, it would introduce quality loss if used that way.

[Aliyah]

I appreciate all of the information that I have received and I am learning a lot. However, I think that I had some misinformation when I started this project and perhaps I should back track a bit...

Can someone explain to me how to...

1)convert a ripped dvd chapter (a dance segment in vob format) into a format that allows me to edit it for video clips viewable in windows media player.

Notes: I'm not very knowledgeable about codecs and which ones I need for this project. I have installed some, but I still may need others. And when using trial versions of some programs such as winavi and magic batch convertor I get video, but no audio and I am not able to import the file to edit it for length.

Those are my issues:) If someone can help me sort them out...
then I can ask better informed questions:)... (does that make any sense?)

Thanks,

I've already recommended a single software application that accepts VOB input, allows you to edit, and can create a low bitrate .wmv file suitable for streaming via Windows Media Player.

But if you want to attack this piecemeal, I will try and help.

First, lets find out what kind of soundtrack do you have in your VOB set? Since you're using DVD Decrypter, make sure you're using it in IFO mode, and then look at the Streams information text file.

Second, have you tried using IFO mode with Stream Processing enabled, and demuxing your MPEG-2 video (.m2v) and your audio (.<whatever>) into separate files?

[Aliyah]

This is the information in the text file:

0xA0 - Audio - LPCM / 2ch / 48kHz / 16bit / LBA: 553276 / PTS: 00:17:19.297 / Delay: -326ms
0xE0 - Video - MPEG-2 / 720x480 (NTSC) / 4:3 / LBA: 553275 / PTS: 00:17:19.623 / Delay: 0ms

The sound and the video are in two separate files. My problem is I don't really know where to go from here.

I have tried to download the trial version of ulead, but when I click on the link to the download the site gives me the boot. So I haven't been able to try that program yet...

What do you recommend I do from here:confused:

Getting there slowly, but surely (I hope:D )

Your soundtrack is in Linear PCM format. [list=1] Does the soundtrack file have a .wav filetype?
What happens when you play it in a player?[/list=1] `

[Aliyah]

Nope, these are the files that are transferred to my hard drive:

Default {"audio playlist" contains 115 bytes}; VTS_01 - Stream Information; VTS_01_0.IFO; VTS_01_1 {vob file, contains just audio}and VTS_01_1 - 0xE0 - Video - MPEG-2 - 720x480 (NTSC) - 4~3 {just video}.

What do you recommend I do from here?

I truly appreciate your time and help.

I assume your "just video" file has a filetype of .m2v?

You are missing a .wav file. You must re-run DVD Decrypter, IFO - mode and enable streams processing. Apparently you selected the video last time, but you must go back and select the Linear PCM audio stream, and select Demux. That should produce a .wav file.

[Aliyah]

Hmm,
I was 99.9% sure that I had selected the video as well, but I re- ran it to be certain... I made sure it was selected and the files that I previously mentioned are the only ones that are produced. The video was converted to MPEG2 and the audio was saved to this file "VTS_01_0.IFO; VTS_01_1" as .vob :confused:
Is there perhaps something in the settings that I need to change? (right now its on default setting)... am I missing codecs? is this project becoming the pain in my ass?:mad: just kidding...
Please let me know what else could be the problem.

Thanks so much for your help,

An .IFO file is NOT Audio. It is a descriptor for an associated VOB set. See DVD structure (http://www.doom9.org/dvd-structure.htm), one of the 13 links in Doom9's The Basics (http://www.doom9.org/dvd-basics.htm) section.

Audio in Linear Pulse Code Modulation (called LPCM or PCM) format should be demuxed into a .wav file on a PC. Select the PCM stream, select Demux, but do not select Raw. A .wav file contains a header followed by raw PCM data, and you want that header created for you.

See Doom9's DVD Decrypter Guide (http://www.doom9.org/dvddec.htm), and the following post and thread in the Decrypting Forum:

[Aliyah]

That part I already understand :cool:.

I noted that the audio was saved in this particular file "VTS_01_0.IFO; VTS_01_1" (for whatever reason). I am aware that it is not an audio fie per say-- it opens with power dvd, no video-- just audio. What I do not understand is why I am not getting a wav file. I followed the instructions in the guide prior to joining the forum and was having this problem. That's why I joined- so someone with more experience can help me troubleshoot:). For the record, I also had a similar "video, no audio" problem when using a trial version of WinAVI and FlaskMPEG (and I believe one other program) so perhaps there is something else going on...

As mentioned before, after following the steps in the guide and those given to me here- the only files that were placed on my hard drive where these: Default {an "audio playlist" contains 115 bytes}; VTS_01 - Stream Information; VTS_01_0.IFO; VTS_01_1 {a vob file, containing just audio}and VTS_01_1 - 0xE0 - Video - MPEG-2 - 720x480 (NTSC) - 4~3 {containing just the video}.

Both video and audio were selected in the streams process and RAW was not. I'm really stuck here :confused: :confused: :confused:

I do appreciate the help and all of the information... keep it coming, believe me-- I'm listening.

if you have a vob file that only contains your audio you can always just use dgindex to extract the audio! ... guide (http://www.doom9.org/mpg/dgindex.htm)

PS: you can of course discard the d2v file afterwards as it won't be of any use...

[Aliyah]

Cool,
I will give that a shot this evening.

I'm quite confused by the file names you've been using, Aliyah. They seem to be missing the usual 3 letter filetypes as part of the names. Microsoft Windows calles these "file extensions." The ones we've been describing have filetypes of .VOB, .IFO, .wav, .wmv, .m2v, and .txt. Y

I'm even more confused by an apparent single file you named "VTS_01_0.IFO; VTS_01_1" which seems to have a filetype within the name, along with a semicolon.

Please open the folder again, and in the Windows Explorer, do the following: "Tools ... Folder Options ... View" Clear the box in front of the option "Hide file extensions for known file types" Click the OK button.Then you should be able to see the complete file names that appear to be missing. That should help us both understand what you actually have in the folder.

Aliyah--It's a shame to see so much effort by all parties involved, and yet, no resolution. If you've solved your problems, please let us know how you accomplished this, if not, come back and get more help. Imagine the confidence it would give someone facing your exact problem if they had a complete road map to follow.
