What is the easiest way to add or replace existing audio DVD sound track

[pwangdel]

Greetings:

I've ripped a Chinese DVD to IFO and VOB files. I would like either to add or replace the original sound track with my own AC3. I plan to convert the vob to avi, convert my AC3 to wav, use Ulead Video studio pro to add the second channel or replacing the original one and finally use Tmpgenc to create the DVD. It would be a better approach and may be quicker if I can add the ac3 directly to mpeg2 then re-author with Tmpgenc. What is the easiest and quickest way of doing this if there are any?

Your time and help is greatly appreciated.

Wishing you all and your family a happy and healthy Holiday Season's.

You don't have to convert. Use pgcdemux, muxman and vobblanker. See http://www.digital-digest.com/articles/Simplistic_Guide_for_Replacing_DVD_Streams_page1.html

Just add the video folder to tmpgenc dvd author and replace the audio with your ac3 and author.

[MOVIEGEEK]

Or use DVDFlick to add the audio track.

[Baldrick]

Yep, that is probably the easiest method. But you can keep the original menus if you use the method above....and with help of guides it wont be that tricky.

Although this method talks about adding a new subtitle file, you can also use this as a guide to replace or add a new audio track.

Just put the new or replacement audio track in Muxman and generate the new VOB, etc. files.

I can ever thank you all enough for your valuable input. You all save my days.

Since I am lazy and already have TMPGenc DVD authoring 3, I will start the easiest way first with TMPGenc, DVDFlick. If the previous two doesn't workout as I expected. I will tackle the Digital-digest guides and Videohelp guide.

I will keep you update of how things work out.

[johns0]

Remember to add the folder from a dvd,hdd..etc option in tmpgenc,not as a file.

[pwangdel]

Here is the update.

The process is very easy once I follow your advice. However, the pictures quality seems to be loss compare to the original DVD even though the rendering format is the same as the original i.e 720x480 4:3. Effectively, the tmpgenc authoring DVD picture quality is a bit grainier, blurrier, not as sharp as the original. Is this normal?

[johns0]

This would only happen if your source was bigger than 4.37 gb and you let tmpgenc transcode it,if it didnt transcode it then the picture quality would be the same,if you want the same quality and its too big to fit on a 4.3gb dvd then set the tmpgenc authoring project to 8025gb and burn with a dual layer dvd(verbatim).

[pwangdel]

You rule .

After following your instruction, the picture quality is now equivalent to the original, no more blurry and grainy.

What I still don't understand is tmpgenc transcode a 6.8GB into 4.37GB movie. How come the re-authoring folder still shows 6.8GB exactly like the original DVD and not in a compress 4.37GB?

Can I ask for a little help please? I have a original DVD with 31 titles each includes a single chapter. Originally this DVD have only titles select menu. The DVD have only one video stream and only one audio stream (English). I have a MP3 audio stream in Bulgarian. I want to add a second audio stream to this DVD.

Now, following the Baldrick's gude I have:
1. ripped the DVD to my HDD - done and OK
2. demuxed audio and video streams - done and OK
3. synchronized the English and Bulgarian audio streams - done and OK
4. converted the MP3 stream to AC3 stream - done and OK
5. muxed a new VOB with two audio streams - done and OK
6. using VOBblanker I have replaced titles with my new VOBs - done OK

The problem is that the original DVD was a single audio stream.
Now on my result I can change the audio stream using the audio selection button on my DVD player but each time a new title starts - the language sets back to the default value (stream no 1 - English).

Is it possible to add a language selection menu (audio stream selection menu) or a way to keep the language selection across the titles?

Also I have demuxed each title separately (with PGCDemux) - is there a way to demux all titles in one pass? Maybe this is the problem?

Thanks for your help in advance.

The videos are in English but you want to have it play the Bulgarian by default? Reauthoring with the Bulgarian one first should get you what you want - all videos should now play in Bulgarian. In your step 5 above, load the Bulgarian audio first, followed by the English. In PGCEdit after you're finished you can rename the audio from the earlier English to Bulgarian, if that's important to you.

is there a way to demux all titles in one pass?

I know of no way, but maybe someone else knows differently.

[babailiica]

The problem is not which will be the default language. I just want to keep the selected language across the titles. Because the result I have now is every time a new title starts - the default language sets back. I want to select audio track 2 while playing first title and when second, third etc. starts I want the audio track 2 to be selected by default.

Also is there any tricks while burning double layer DVD?
Because original DVD was DL - about 6GB and now it becomes 6.2GB including second audio stream and I don't want to resample or compress the video stream. I think just to burn it on a DL DVD.

Since you don't know anything about how to do these things, I told you the easiest way - have the Bulgarian become the default language track by loading it first when reauthoring the various titles. Sure, you can run a trace in PGCEdit to find the command that's setting the audio for each title, you can mess with the NAV commands, you can place an SetSTN command at the beginning of each title to have it play the 2nd audio, but these things are a bit more difficult to accomplish for someone that's never done it before.

I don't know anything about burning dual layer DVDs so perhaps someone else can help with that. But if you're not using ImgBurn for burning to disc, you're doing it wrong.

[babailiica]

Thanks for trying to help. I'm a software engineer but for the video stuff I use Pinnacle Studio to burn from my miniDV to DVD and that's it.

If I cant make a DVD to keep the selected language for the audio track across different titles than there is no sense to have a second language at all. It doesn't matter which language is default and which is second because you can't ever play a full movie from the first title to the last with the second audio track. Than it seems more reasonable just to replace the English track with Bulgarian.

I try to edit the VIDEO_TS.IFO to add the second language under VMG_VTS_ATRT for each title by copying values from the remuxed IFOs but no result.

Now I think to try something else. I will create a new DVD from scratch and will include an audio track selection menu, will rebuild the root menu and will include only half the titles. I will use the source M2V and AC3 files from the original DVD and will see if it finally will keep the language setting. This way I will have to rebuild the menus (unfortunately I don't have the original motion picture for the menus and will have to replace it) but I can split the DVD so I don't need a DL media. Hope I will find a good guide on how to create a audio track selection menu... still not sure what to use for the authoring. Maybe will try DVDLab

Well, if you're going to start over you may as well make them all chapters rather than titles. That way picking an audio language will ensure it remains the same unless changed. And when changed it'll remain the same unless changed again.

But you don't really have to start over again. Just run a trace in PGCEdit to find the command that sets the language and change it to the second language. But, as I said earlier, this may be beyond your current capabilities.

Here's a guide that kind of does what I suggested earlier. But rather than reauthoring and switching the audio tracks, it renumbers them in the already finished DVD, thereby switching them:

http://forum.digital-digest.com/showpost.php?p=296707&postcount=1

You'll have to do the same thing for all the titles, though. And if this is a movie, you made a really big mistake to begin with by changing all the chapters to separate titles. And that mistake is coming back to bite you in the a**. Maybe you weren't responsible for that. Your first post was unclear about that.

Well following a few guides and reading a lot of PGCs in IFOedit I finally fixed it.

1. In the VIDEO_TS.IFO I have added the proper language (values from the remuxed VOBs)
2. For each VTS_##_0.IFO I open VTS_PGCITI and for each PGC I add the second audio stream (and fix the first as it was wrang on the original DVD)
3. For each VTS_##_0.IFO after adding the second audio stream on the root page I have changed the audio settings for the second stream as follows (bolded needs change):
* App Mode: Unspecified
* Language: Bulgarian
* Coding Mode: Dolby AC-3
* Sample Rate:48 Kbps
* Quantisation: DRC (dynamic range control)
* Extension: Unspecified
* Language type: present
* Multichannel extension: not present
* Channels: 2
4. For each VTS_##_0.IFO I open VTSI_MAT
[00000203] Number of audio streams in VTSTT_VOBS (this is where I have 2 languages described after)
I have changed the value from 1 to 2 and seems that this was the key!

I have read the menu commands and there is no SetSTN... so the only problem was that the IFO files was missing a proper setup for 2 audio streams!

About the titles and chapters - to have 31 titles each with single chapter was a decision of the original DVD author - not mine This is a historical movie and each title is a separate story. But all titles are the same bitrate, resolution etc.

Anyway, manono, thanks for the support...
Next task will be to fix all IFO files... check and double check entire DVD
And than will have to experience burning a double layer media

Burning a DL is (currently) not difficult. Use ImgBurn, and you will be prompted for the "layer break" position. It's the position where the player switches from layer 0 to layer 1, and that operation takes 0 to 2 seconds, depending of the player. So, select a position where that pause is not too noticeable. Since your DVD is made of several short titles, chances are that you will be able to select the beginning of a title for the layer break position, and you will not notice it at all. Anyway, ImgBurn has a good GUI, and it will pre-select the best layer break position for you. If it cannot find the best one automatically, you will have to experiment with the preview.

If you wish, you can also tick the "seamless layer break" option. That option sets the "seamless playback" flag on the layer break position, telling the player to ignore the layer break pause, and, although that method is not legal, most recent players will accept it and switch to layer 1 without any pause at all.

Remember to use good media (Verbatim), and burn at a speed slightly slower than the maximum speed accepted by the burner and the media.
