Creation of a DTS/5.1 Demo-DVD from recent Movie-DVD´s

[g.henk]

Hello,

I would like to build a Demo DVD to show customers what Dolby Digital 5.1 and DTS is all about.

On this DVD I would like to arrange several sequences from Original Movie DVD´s as well as 5.1 wav files as the source.

The task would be to select short sequences from the original DVD material and reathor them in a way so that there is no need to break up the vob files into pieces. I would like to just select a sequnce out of the original movie an temporarily store it to the hdd until I have all pieces together that I would like to combine into a simple text menu and burn to the DVDR.

I tried doing it with TMPG 3.0 Express and it was looking if it could work fine.
I was able to put in my old Demo DVD and import the tracks. But if i import all tracks from my original demo DVD the files occupy twice the space as on the original DVD?! Express also tells me not being able to handle the ac3 tracks. (I don´t have the ac3 plugin - would this do the trick?)
My old Demo DVD is only 3GB in size.
But any way I would like to select sequences from new DVD´s.
I know how to temporarily store them to my HDD but how do I choose only a few seconds without reencoding and loosing 5.1 sound?


I am familiar with the following tools:

TMPG, Enc, Author, Express
Sony Vegas
VirtualDUB
DVD Shrink

But what do I really need to accomplish this task?

Many Many nice Greetings

You could load then into DVD Shrink, select reauthor, drag the title to the left hand pane, then right-click. You then get an option to set start and end points. Set these to match the scene you want to keep. When you back this up, you will get just that scene, with whatever audio you selected.

If you don't want a menu, you can use DVD Shrink to put all of these bits and pieces back together again as a single disk.

If you do want a menu, then you need soemthing like DVD Lab Pro, which can handle DTS and AC3 5.1, and allow multi-VTS title creation, which you may need if you DTS and AC3 audio aren't all on the same tracks.

Adding DTS and AC3 wav files will be much more difficult. They don't fit into the DVD spec, so they cannot be authored like any other track. They would have to go int he data folder, which your player will ignore. I would suggest burning them to a seperate CD for playback.

As to why your old demo disk blew out in size - I suggest it is because tmpg 3.0 express doesn't like the audio and is converting the AC3 to 2 channel LPCM, and probably ignoring the DTS altogether.

Hi guns1inger,

thank you very much for your extensive reply. I will try it this way and report back to you with the experiences I make.

Burning the 5.1 wav´s sound like an idea, because that is the way I used to do it and it always worked fine. But it would be nicer to have them on the DVD also as a different Menu item. How about converting them to ac3 or combinem them with just a blank (black) video of the same lenght.

Ciao
