Neuron2,

One will never cease thanking you for the energy which you grant to the optimization of your DGindex software.
It is a treat for all one each one.

Nevertheless (like the accustomed of Guada2), could you explain me the difference between the mode "Demux all track" and "Demux" (Audio/Output method)?
Because I discovered small Difficulty which challenged me on the RIP of a DVD of "fishing".

With the option "Demux all track", I obtained 2 MPA, whereas the option "Demux" provided me only one file MPA.
You will say it to me is completely normal. But the size obtained with the 2 files were different.

In made, my goal was to recover file MPEG media and the audio of the other.
And then to multiplex the audio and video files.
But the problem came from the 2 files obtained with the option "Demux all tracks".
Impossible to have the multiplexing of the file audio2 with TmpegEnc.
For that I preferred to use "Demux" and the result was conclusive with TmpegEnc.

Could you inform me on this aspect of the demultiplexing.

Thank you.

You can select which audio track you want to demux. Doesn't that work?

@neuron2,

Thx, very much!!!

Thank you Wilbert, I am conscians of that.

But the problem was much deeper than that, because with mode "IFO" I did not have the total file of film.
Thus I have ripped then the contents by selecting the "Files" mode of Dvddecrypter.
And there, it is not the same thing.
It was necessary that I find exactly the first scenes of the film.(removing the useless beginnings)
And there, there was part of the film which was detached from the others, which enabled me to see it with the option "Demux all track".¶
But what I did not understand, it is that by selecting "Demux" the totality of the audio at summer taken into account.

Thus which is the interest to choose the option "Demux all track" if I cannot multiplex correctly my movie;even if it tends to do its work correctly.

Thank you in advance

Thank you, guada 2. It is an honor for me that my efforts find some utility for you and others. Don't forget, however, that jackei is at the root of all of this. Thank him more profusely.

"Demux all tracks" will demux all tracks that are found in the VOBs. Typically, you might get several. You might get different languages and you might get 5.1 dolby and normal MPEG stereo ones. The former will be larger than the latter. "Demux" just demuxs the specified track. The problem with that is you don't know which track is which. I plan to address this deficiency.

Sure. Probably one is Dolby and one is just plain stereo.

I believe TMPGEnc needs a special plugin to handle AC3.

Maybe that was the normal MPEG audio you demuxed.

I assure you Neuron2.
I know very well your software and that appeared strange to me.
Of course, the work carried out by "Demux all track" was done well thus that "Demux".

What challenges me, it is that the two files are really MPA recognized by TmpegEnc.
To understand the problem, I have make 3 tests with TmpegEnc (option Demux all track):

video+ mpa1/mpa2 = video+mpa1
video+mpa1 = video+mpa1
video+mpa2 = video+mpa2

With the Demux option, I obtained a file MPA.
I tried the multiplexing of audio file mpa with the video one in Tmpeg, it was OK.

to tell the truth, I did not understand why but I know that I had succeeded.

But I will stain to find to rather the this DVD (that of a friend) to give you the essence of my acts and my conclusions.

so long.

Of return,

Benefitting from the occasion to supply me and restore me before resuming work, I screened my external HDD of 250go 7200trmin-1.
The RIP of the DVD of fishing appeared in it:
Course of operation:
- use of the final version of DGindex;
- RIP of files VTS 01-1 to 60-1;
- file 1: Save project and video demux + Demux all track = 1 D2v file + Mpa layer2 T01 48khz/192kbps (138mo) + Mpa layer2 T02 48khz/192kbps(3.73mo) + film m2v (3.77go).
- file 2: Save project and video demux + Demux = 1 D2v file + Mpa layer2 T01 48khz/192kbps (138mo) + film m2v (3.77go).
- Use of TmpgEnc More for the multiplexing of the audio and video files;
A/ MPEG Tools then Multiplex file 1 = film m2v/ mpa t02
B/ MPEG Tools then Multiplex file 2 = film m2v/ mpa t01

Report:
incorrect A / correct B

Question:
Which explanation can you provide me on noted final A and B?
Thank you to clarify Neuron2.

Are you saying that the track 2 MPA files obtained from "Demux all tracks" and "Demux" are different?

And what is "138mo" and "3.77go"?

Finally, what does "incorrect A" actually mean?

Try to keep things simple for my simple brain. Thank you.

I love this conversation

@guada 2,

1) If you select track 2 in dvd2avi, select demux and create the d2v file, then you will get the T02 track. Correct?

2) To be clear. T01 is the audio of the movie right?

3) Usually the second track (T02) contains the directors comments, but the file is too small. What is it? Is it really a part of the movie?

@neuron2,

I guesss he means 138 Mb and 3.77 Gb.

I think that I owe you the truth.

Here, I have a friend who wanted avoided having files VOB on his computer.
For that, I proposed to him to give him the contents of film in native Mpeg2 to multiplex with MPA.

Therefore, to make this operation, I used the software Dvddecrypter, Dgindex beta5, and TmpgEnc Plus.

With the mode IFO, Dvddecrypter did not recognize the totality of the report of the DVD "fishes".
Thus I used the mode "FILE" which selected the whole of the VOBS (Vob 01-1 until Vob60-1).
With DGindex, I chose the mode "Save project and video demux" to recover the audio file, the file d2v and the file Mpeg2 (m2v).

By defect, I left "Demux all track".But I discovered that there were 2 files MPA.
But to trust of my work, I have decided to use TmpgEnc Plus for the multiplexing of the m2v and 2 MPA (MPA T01 and MPA T02).
As by practice, I chose to view my work but the MPA T01 was missing.
I thus proceeded differently, by choosing the option "Demux".
Only one file were selected it is the MPA T01.
Thus I tried my chance second once with TmpgEnc Plus.
That functions.

Which are from now on your deductions?

Enter bracket:
I always thought that the language official was that of Guada2.
It could be well that I add the RULE 17 to this forum.

First you say that "there were 2 files". Then you say one "was missing". I just cannot make any sense out of this.

Can you please state directly if you think there is a problem with DGIndex and what it is? If there is one, you should be able to state it without bringing in all this other software. For example, like this: When I demux track 2 using "Demux" the resulting file is different from the one I get using "Demux all tracks". That is just an example, but shows the kind of trouble report that I am able to understand and deal with.

Hello Neuron2,

I fear not to be able to explain you what I do not understand very well.
Nevertheless, I assess your qualities of listening and research.

How to render comprehensible you that in a simple way.

In short…
Dgindex beta 5 can extract the file d2v, the audio file (here it is audio MPEG) and, the file Mpeg2 (m2v) with the mode "Save project and video demux".
Until now all is normal.

The choice of the audio option by defect it is "Demux all Track", nevertheless it is possible to choose the option "Demux".

If your film lasts 1 hour and that you obtain these results:
Demux all track:Mpa 1 (130 mb) + Mpa 2 (3 mb) for Mpeg2 (m2v) of 3.77 GB
And;
Demux:Mpa 1 (130 mb) for Mpeg2 (m2v) of 3.77 GB

What you would think?

What challenges to me is the final size of the film m2v.
Why the 2 options does not propose same testimonys according to this size?.
The extraction of the Mpeg2 file would be it incomplete?

NOTE:
Knows that I already reproduced 5 same times handling.Always the same result.

Which is your verdict now?

What you would think?
I would think that the VOB has a video stream of size 3.77 GB, one audio track of size 130 MB, and a second audio track of size 3 MB.

The M2V is the video stream. It is the same size in both cases, as it should be. Why do you think it should be different?

If you are asking why there is a short audio track, I don't know because I didn't author the DVD. Have you listened to it?

So again, why do you think there is a problem?

@guada2 - Are you asking how the m2v file remains the same size regardless of the number of audio files that are created?

EDIT - neuron beat me to the question.

I think the best advice, without sounding out of order, is for some better language translation to be in progress, it can be quite difficult to know exactly what's being asked....

Indeed Cybéria,

I believe that you guessed my interrogation.
Think you that it is normal?


Small interlude: " I don't know because I didn't author the DVD. Have you listened to it?"(neuron2).

Neuron2, you know that you are right on a point, the DVD is not entitled Neuron2, and in more you are not the producer.
It is really pity, for a small spirit that believe not to possess Neurons, you really touch me.


So again, why do you think there is a problem?

For my part it is not a problem, it is just the synchronization which carries the hat.

As to say then design of the option "Demux" and "Demux all track" since the file m2v remains unchanged.
It is necessary to believe that arrives only at me.

In brief, I thank you to all.

The M2V file is the video of the movie. Its length does not depend on which audio tracks you choose to demux.

I would guess that the bigger MPA file is the audio of the movie. And I would guess that the playing time of the video and the playing time of this audio track will be the same. I do not know what the smaller audio file is, perhaps it is some audio to play during the menu of the DVD?!

Please report the playing time of the M2V and that of the larger MPA. If they are the same, you should be able to use them to create a sync'ed movie.
