Put a 2 dvd-disc on one Dvd-r using dvd2dvd!

[mcmanuf]

Hi.
I have tried to put two dvds(Godfather Part II disc 1 and disc 2) on one dvd-r disc for a long time now, but have never succeded. And I want to use the magneficent dvd2dvd to perform my request. I usually build up my image in Dvd maestro after having the final ac3 sound and m2v file ready.

I would like to use D2SRoBa 1-pass (using cce) as its fast and the quality is good.

So what am i supposed to do?

I know its an option to set the final output for disc 1 to 2200mb and the same for disc 2. And at last use dvd maestro to build the two video tracks. But the timecode on my dvdplayer will reset after disc one and that isn't quite the desireble effect.


Really hope anyone can help me.. Have tried many things but as said never succeseded in any!

Never tried DVDMaestro, but here (http://forum.doom9.org/showthread.php?s=&threadid=76408) is a thread with some ideas/guides...

Acually I found a solution myself. Well itwas already described in the faq.
Q41.

But thx anyway..
I know that i should have read the faq first, but most of the time it never helps
in my situation.

[jsoto]

Q41 is not a safe method. You can experience some A/V synch problems and not sure what will happen if the audio tracks you want are not the same in both movies.

I believe any of the methods described in the thread I pointed you are better. Dvdshrink is the easiest way if you do not want menus.

Thx for your help jsoto.

I have just started doing a combine using the faq question 41.

But i have done it after using dvddecrypter>stream proces.

I will inform you of the proces if interested!



Ps. I do think that there is a problem using dvdshrink. The program will do the compression for you. That is not of my interest. I will use cce for encoding! but thx anyway.

[jsoto]

I do think that there is a problem using dvdshrink No, if you previously encode your movies with DVD2DVD using 2230 of CD size.
DVDSHRINK (in automatic mode) will compress if and only if the final DVD (the one with two movies) does not fit in a DVD-R.

In any case, in order to have the same Q (the same quality) in both movies, I believe it is better to join the VOBs previously to the encoding process, which is what you are doing, but, as I said, it is not a safe method and not always works.

No its not safe at all. Damn thought i was lucky. But you are right.. The audio are out of synch with 2seconds in the second disc.

Ill try the other form link..

My preferred way to do this kind of 2 discs to one DVD-R thing is to do the first and second discs seperately, as half size type encodes, then rename all the .vob's so they are in the correct order, put them all in one folder (delete all the .ifo files) and use IFOEDIT to create new .ifo's (it has a create ifo's button). It's really simple, quick, you get all the original chapters and the audio will be in sync.. Probably not perfect from a VBR using the available bitrate most intelligently point of view, but you can't have everything can you. ;)

[mcmanuf]

Hey ralph thx for your reply.
In ifoedit (v. 0,95)
What do you choose "Create 1 PGC only" or do you choose "Create a PGC for each new VobId".

And regarding the chapters, do you choose the first or second option.
Sry if the questions are stupid, but gotta learn :-)

And at last, what do you mean by "from a VBR point of view".
The reason why i want to use this method is because:

1. The timecode on my dvd player wont show 00:00:00 after the first disc is processed (lets say after1h 30min. And then start to count to 1h 45min again.)

2. When using CCE for encoding, the bitrate are better placed as im processing the whole file at once (instead of processing disc 1 and disc 2 individualy) (well at least I think so)

3. Its less timeconsuming.


Waiting eagerly for your next replies :D

[ralphthedog]

No probs mcmanuf, I just left all the settings in ifoedit alone and it seems to be OK. "Create 1 PGC only" and "create chapters for each cell" are checked on mine as well as "same as source" for the destination directory.

Make sure you also use the "get VTS sectors" button in ifoedit too, as the last thing, it will make sure everything is pointing in the right direction in your new ifo's and vob's.

The VBR point of thing was referring to encoding one half.....then the other half seperately. If you managed to encode the whole thing as one, CCE could possibly better allocate the available bitrate, say if all the car chases and explosions were in the second half of a film. Your DVD player shouldn't get confused timecode-wise, your new ifo's should make sense to it(they are for the whole film, not the first half anymore). Yeah, and it would be less trouble too ;).

[mcmanuf]

ralphthedog:
but you can't have everything can you.

Well acutally I do think I can have every thing :D

But be aware.. This task is very time consuming.
Lets start.

First I demux audio and video using "dvddecrypter" on both dvd's.

I then start up "Womble Mpeg Video Wizard 2003", so far the best mpeg2 editing program as far as im concerned (and it will accept trimming, cutting ac3 audio as well). I join the two m2v files and the two audio files. Ill cut of every bad frame after the first m2v, and make a perfect synch image, as i can manage to give the ac3 files and the video files the same lenght.(it is important to write down when the the lenght of the first m2v files, as we will be using this value to correct subs and chapter points)

Then I mux the files and check in a dvd-player program, to see if everything is allright, just in case :-)

Allready tired. Well we have just begun! :-)

We then demultiplex the mpg files, and we will have a perfect m2v file containing the two discs, and a perfect ac3file.

We open ifoedit and author a dvd. We dont need chapters nor subs at this moment (these things willl be taken later from the original dvd's)
After been waitning for 10 minutes for ifoedit to do its thing, one can have a drink of cofee.

Open up dvd2dvd. (i prefer to use dvd2roba, as its fast and yields good quality). And let it do its thing.


We now need to rip the subtitles from the original dvds. Insert disc1 enter subrip and choose what bmp option you prefer(according to your author program. I use the dvd maestro option as i obviously use dvd maestro. There are sereval guides around the net to help you with this program.)
After disc one is finished, insert disc two.
In the timecode box enter the value you got from mpeg wizard (you remembered to take this value, right! This is to make the subs in synch.
And rip the subtitles. The program will ask you if you wish to add these new subs to the old file, enter "yes".

After the whole proces is finished save the file from subrip.

And last enter dvddecrypter one more time.
Insert disc 1 and rightclick on the main movie(in ifo-mode) and extract the chapter information.

Then insert disc two and once again rightclick on the main movie(in ifo-mode) and extract the chapter information. Only this time you should type the value from mpeg2 wizard. (Hint. The same value used for the subs!)
After having these two chapter files combine them. This is as easy as it gets. open the two files in axplorer and insert all the lines from file two (disc2) to file one(disc1).

Now we finally made it. We have a perfect video file with the chapters, audio and subs in sync. All we need is a Authoring tool.


I use dvd maestro as its easy for beginners and good for professionals.

Hope you did'nt fall asleep during this reading ;)


I have tried numerous ways to combine 2-dvd sets on one dvd-5 but have failed with every guide on the net. And the option with encoding disc 1 and later disc 2 doesnt take that much care of vbr setting.


Although this entire proces seems to be exhausting, one should notice that the whole proces in making a perfect synch audio and video file doesnt take more than 20-30 minutes. mpeg2 wizard are really fast. And maybe there are programs out there thats faster.


The whole proces with everything should take no more than 4-5 hours to complete. (slower if you have a slow computer. My computer is a 3ghz. And the realtime encoding swings from 1,03 to 2,5. It depends on the q factor, and wheater you are using filters or not.)

[ralphthedog]

That's a lot of work because of one stupid comment from me?:)

Would be worth it if you're really pushing the limit regarding what you're trying to fit on one DVD-R I guess(I did the directors cut of Once apon a time in america a while ago...that might have been a candidate!). I'm not sure how much better your finished DVD would be than one done in two halves and combined with new IFOEDIT ifo's though....maybe only 1-2%???.....that might be for cleverer people than me to argue about.

I guess if you only wanted forced subs you could get DVD2SVCD to permanent encode them and forget that bit too.

It's amazing how many different ways there are to accomplish the same thing:p

Hell yeah :-)


Well I learn something new everyday..

[richarddd]

Is there a way to combine the 2 disks into one large uncompressed set of files (properly authored, not just renumbering vob's) and then encode the set?

[DDogg]

Hmm, I've done this many times. Just use dvd2dvd set 2225 (or whatever is appropriate) and set it to make no images. Now you have your elementary streams plus the chapter info. Author with dvdlab. It is very simple to do. You can import the chapter info. You can also set DVDLab to jump to the second video stream automatically after the first is played, or to come back to the menu. Your choice. Perhaps I am missing some requirement you have?

[richarddd]

The choices for turning two disks into one DVD-5 sized movie seem to be:

1) Encode each disk to 1/2 of a DVD-5 and combine them into a single movie.

2) Combine the two disks to one big uncompressed movie, then encode into a single movie.

The advantage of (2) is that the encoder can more efficiently allocate bytes. A problem with (2) is figuring out how to make one big uncompressed movie (just renumbering vob's doesn't always work, as noted).

What am I missing?

[DDogg]

How about a 3?

3) Author sets of elementary streams as separate vob standalone structures on the same DVD, then use the tools available in dvd authoring software to set the playback sequence from one to the next. This makes them, in effect, one long movie. Or, you can set it to return to your menu structure after each is played if desired.
