Author a dvd from two m2v and mpa files

[Creed92]

Hello everyone!
I demuxed a dvd with dvd reauthor pro 4 and now I want to recreate it with DVD LAB PRO 2
The problem is that I have two m2v files and two mpa audio files, to combine into ONE dvd, one mpeg and one title. How I can do that with dvd lab? Maybe the newest releases works better?
(I prefer using dvd reauthor because it take me back the original files from first author, and this dvd was authored from two m2v files)

Don't use either. Just buy the full version of muxman and use it's timeline feature to the 2 video files and 2 audio files into one DVD.

I'd join mv2 in TsMuxer and then I'd try to demux that TS in ProjectX to mv2.
The same with audio. It might work.
Mpa is not allowed for NTSC video, but you perhaps know that.

Or you can always link those separate titles in DVDLabPro, but that is kind of lame, sure.

edit: m2v not mv2 ...

I can't do that with the free version of muxman? The one available from this site.

It seems there are things you still haven't told us --- it's one movie divided into two parts? Or one main video and one secondary/commentary video?

[Cornucopia]

Could be further troubles such as mixed NTSC & PAL..

You could always remux first using Imago, etc. YET..Too little info.

A single video, but authored from two m2v and two ac3 appended.

Yes, you can do that. Use the 'Add' button to combine the video and then the audio, before authoring for DVD.

[Creed92]

Thanks.
I noticed that Muxman works better than DVD Lab Pro
One question: on the new releases of dvd lab pro there are new options and better things or it's all the same? (I have the 2.0 version)

[El Heggunte]

If you want to upgrade your copy of Dvd-lab PRO, don't go beyond the revision 2.24
Newer versions have problems with multiplexing MP2 audio, and some very-complex menus don't let the VM commands be compiled correctly.

Please define "works better"

Well, it's simple, fast and I can create a dvd from various m2v files. On dvd lab pro I can't do this unless I split the movie (title 1, title 2 ecc.)

Well, if there was ONLY ONE title originally, there was no good reason for that title to be divided into Part1.m2v and Part2.m2v, to begin with
Also, nothing stopped you from doing a

copy /b part1.m2v + part2.m2v fullvideo.m2v
copy /b part1.ac3 + part2.ac3 fullaudio.ac3

before using a DVD-authoring program

There is something you have not explained very-well yet, I'm afraid

[Cornucopia]

"copy /b" is a BAD way to concatenate media files, as I've pointed out before. Yes, you will "succeed" in arriving at a single file, but the resulting file will have multiple, possibly conflicting headers, often in the wrong place. Players will have a HARDER time reading the file, possibly even to not be able to read at all.

If you've succeeded with this method in the past, it's been only by pure luck.

The main question is......WHY (demux)?

Speaking for myself, it was not a matter of luck --- I knew pretty well what I was doing
m2v, m4v, h264 and vc1 are ELEMENTARY streams, and if these have the same basic properties (frame rate, frame size, aspect ratio), and don't use open GOPs, copy /b shall work as expected

Exactly what I was trying to say, many thanks for going straight to the point.

Maybe not, but I've seen it happen before where a single film was divided into two different PGCs - two different VTS's even. And what about a long film being divided among two different DVDs, or divided among the two halves of a flipper DVD?

Is this a serious question? Maybe to shrink the size to a DVD5? I can't speak for Creed92, but I do that all the time. Or to reencode into some other format. I do that all the time too.

Maybe other programs can do it - I haven't used them all - but the fact remains that Muxman is the only authoring program (I've seen) that can join multiple M2Vs into a single title. I use it myself for that feature with some regularity. I'm compressing down to a single DVD5, and in order to give the main movie better quality will encode the credits separately with much lower quality. And then join the two during authoring. Or the case with anime sometimes where an opening song or maybe the end credits are 29.97fps while the main body of the episode is 23.976fps. Encode them each separately (the film portion with pulldown applied) and rejoin them during authoring. There are several reasons to use this feature of Muxman's, but show me another authoring program that can do it. Apparently the beloved DVDLab-Pro can't.

TMPGEnc Authoring Works can do that as well.

@ manono --- thanks for the detailed explanation

[Creed92]

There's need to say that this dvd is an homemade dvd, so dvd 5 already.
I demuxed it because the original mpeg is a little glitchy.
I used dvd reauthor pro to extract video and audio streams, and Muxman for reauthor the same dvd without loss of quality (even if the size is different, right?)

[_Al_]

How different, 5kB or 50MB?

[manono]

I used dvd reauthor pro to extract video and audio streams...

It's this DVDReauthor you used to get the audio and video? And it's also what gave you 2 M2Vs and 2 MPAs? What did you do, demux by VOB? Or did you split them in the process of 'fixing' the 'glitches'?

Anyway, in case you're wondering, you can demux into a single video and audio file using DGIndex or PGCDemux (PGCDemux assuming they're part of the same title).

[Creed92]

DVD Reauthor start by the IFO. file of the dvd
I believe that the dvd was autored from two m2v because the ''glitch'' stands in the middle of the join point of them.

@ _Al_ : 2 kb
