View Full Version : Extracting .VOB / .AC3 files from DVD for LW reference!

Hi People!

Bear with me on this (long text, sorry!) . . . :)

Okay I know this sounds really, really dodgy, but please let me assure you I am not about to go and rip off a whole bunch of DVDs!!!

What I'm trying to do is pull of a small section of a movie so I can use it as a reference for a project I'm going to try to do.

Being able to play it back off my hard drive is much more handy, as my DVD player is at home, and I'm using the computer here at work which doesn't have a DVD drive.

However one of the Macs in the building does, this allowed me to copy off the .VOB files which contain the movie.

So here's where I got to so far . . .

Copied off the .VOB file I need (found the right one by trial and error!)

Analysing the VOB file with TMPGEnc I know that it's made up of:

Video
MPEG-2 720x576 @ 25fps (9800kbps)

Audio
Dolby Digital (AC-3) @ 48000Hz (384kbps)

Despite the fact that Windows Media Player can play MPEG-2 files, it won't play this one.

I've tried playing renaming to .mpg, de-multiplexing the audio and the video, but it doesn't make any difference, any ideas on how to play/convert this file would be great!

I managed to convert the audio part from AC3 to WAV using an AC3 decoder, and although it works, the converted audio isn't quite right, it seems kind of speeded up and jittery.

The reason I need to do this is for a personal project I want to do in LightWave.

I want to recreate the ED-209 boardroom scene from the first Robocop movie but in CG, mainly because it will be a good modelling / texturing and rigging exercise for me, it's also one of my favourite scenes, ED-209 is easily the star of the movie for me!!! (Craig Davies did a great job <- ED209 designer)

It would also be interesting to do because CG wasn't available to Paul Verhoeven when he made the film so it was all 'go-motion' animation (Phil Tippet).

There are other ways of capturing the audio, which is the more important part of this exercise, as I want to match the CG with the audio from the film.

So basically any ideas on how to grab the section as a playable movie? Failing that the audio without the errors?

I realise this is copyright hell but I'm doing this as a personal project, not to earn any money as a result.

Thanks for any help!

Cheers
Matt

Hi Matt,
if you can open the VOB in TMPEGEnc, why don't you select the scene you want and do a File->Output to File.
Shouldn't that work?
Cheers,

I wish it was that easy, it's weird, TMPGEnc can write perfect MPEG-1 / MPEG-2 files, de-multiplex .VOB (after they've been renamed to .MPG) can read MPEG-1 files but not MPEG-2!!!

Go figure!!!

Aside from all this, my machine seems to want to restart Windows Explorer every time I click my right mouse button, every time, dunno what I installed to make it do that, but it's REALLY annoying me now!! I can't use my right mouse button on the desktop!!!! Anyone else ever have this oddity?

Here are some links that will help you out. You might want to check them quick before Mr. Moderator deletes them, as Newtek Mods are big into Censorship.

That should get you started into archiving your DVD that you purchased for your personal use. If none of the links are there or working just PM me and I will get them to you.

The Ed-209 was cool, the movie was campy, Paul Verhoven can suck turds in purgatory for making "Star**** Troupers".

The mods are not big into censorship. They are big into keeping the message board appealing to their customer (and potential customer) base, as well as being very big into avoiding lawsuits Newtek doesn't need.

I can't see now NT would get intro trouble by _me_ posting this, but if they feel the need to remove it I'll totally understand!

Wizcracker, thanks for the links I'll check them out, although I'm consigning myself to recording from the DVD onto MD for the sound and using reference images (have quite a few now) for the modelling.

Video would be useful when rigging the character, I suppose I can always take notes when watching the DVD!

Geez, you'd think with todays technology this would be easy!!!!

:)

Cheers

There is lots of software out there for doing what you are trying to do. TMPGenc is good... but in my experience Clad DVD XP (http://www.clonead.co.uk/) is the best software for pulling out the vob without protection... then you use DVD to AVI and TMPGenc to do a little editing. Also, based on what you seem to be wanting to do, you probably could use Animation Shop or somthing similar to pull out the frames of the avi into jpg format and then pop those into a background layer in Modeller.

I don't remember exactly where I found it (on a magazine CD cover I think) but there is a freely downloadable registry hack that will allow you to play vob files directly inside of windows media player....
