My Remuxing Guide (beta)

My Remuxing Guide (beta)
Courtesy of
2CL

Note: I’ve done this successfully with using a ReJig m2v but have not tested on other m2vs done with CCE or TMPGenc. I hope this works for those too but if it doesn’t, somebody please let me know. With that said, let’s start.

________________________________________________________
Checking for Audio/Subtitle Delays

1. Open up one of your VOBs, to be muxed with a m2v, with VobEdit.
________________________________________________________
2. Go topside and go to Edit / “Get Video/Audio delay”.
________________________________________________________
3. You’ll get a pop-up message with your delay information.
  • If you have zero delays in any streams, then proceed to next step
    If you do have delays present, then go to step 11.

________________________________________________________
4. Remuxing with Zero Delays

Open the IFO of the VOBs, that you will be remuxing, with IfoEdit.
________________________________________________________
5. Go topside and click on VOB Extras / Remux .m2v or click on "VOB Extras" button. You should have your “Re-Mux” option checked by default and “Strip Stream’s” unchecked. Leave other default checkboxes as is for now.
________________________________________________________
6. Set paths for your destination directory and .m2v stream. When done, uncheck “AutoCopy Menu-Files to destination” and click OK to start remuxing process.
________________________________________________________
7. Uncheck “AutoCopy Menu-Files to destination” and click OK to start remuxing process.
________________________________________________________
8. When done, drag/cut your new remuxed files over into your original folder and replace the old files.
________________________________________________________
9. Click “Get VTS Sectors” button to correct IFO.
________________________________________________________
10. Play to test. You shouldn’t have no out of sync audio and video.
________________________________________________________
That’s it

11. Remuxing with Delays

In this procedure, we will be using VobEdit for remuxing instead of IfoEdit. The only drawback is that VobEdit requires you to use the single VOB in which you had previously demux it’s m2v stream. If your original Titleset had more than one VOB, we need to have them joined into one single VOB for remuxing to be successful with VobEdit. DVD Decrypter or vStrip have the option rip Titleset VOBs to one single VOB. If by chance you have your VOBs not joined, you have the option to rerip your VOBs again to one VOB or you can merge them all using a free tool , available for download here at Doom9, called FileMerger in the VOB Tools sections. When you have your single Titleset VOB, proceed on.

Now, open this single VOB with VobEdit.
________________________________________________________
12. Go topside and click on Edit / Remux m2v.
________________________________________________________
13. Browse to your m2v file
________________________________________________________
14. Browse to a destination directory for your remuxed files to go to and press OK to start remuxing process.
________________________________________________________
15. When done, you should have new VOB files like

VTS_*_001.VOB
VTS_*_002.VOB
VTS_*_003.VOB


Rename them back to

VTS_*_01.VOB
VTS_*_02.VOB
VTS_*_03.VOB

________________________________________________________
16. Just in case, here’s a good time to check you VOBs for audio and video sync. You should have no out-of-sync VOBs. I guess VOBedit does a better job at remuxing with delayed streams. Also, if you are hard pressed for disk space, it’s safe to delete your single VOB and m2v.
________________________________________________________
17. With renaming done, drag/cut your new remuxed files over to your original folder and replace the old files.
________________________________________________________
18. Your IFO’s VTS_TMAPTI (time table) does not match what you have in your new VOBs now so we must correct that. So, open your IFO with IfoEdit.
________________________________________________________
19. Click on VOB Extras buttons.
________________________________________________________
20. With default checkboxes checked, the only things you need to do it check “Strip Stream’s” and browse to your destination directory. Click OK.
________________________________________________________
21. In your Stream List window, click on “Check all” button and then “Strip it” button to continue.
________________________________________________________
22. When done, drag your new files over into original folder.
________________________________________________________
23. Click “Get VTS Sectors” button to correct IFO.
________________________________________________________
24. Play to test.
________________________________________________________
That’s it.

Remuxing Menus

If you want to remux your menu m2v back into your menu VOB, it’s pretty easy. Just follow steps 11 to 17 above and here are the other steps to follow.
________________________________________________________
18. Open up your IFO in question and click on “Menu Extras” button.
________________________________________________________
19. The only thing you need to do is enter a destination directory path. Press OK
________________________________________________________
20. In your Stream list, keep all if streams are present.
________________________________________________________
21. Click “Strip it” button.
________________________________________________________
22. Replace your old menu VOB with your new one.
________________________________________________________
23. Click on “Get VTS Sectors” button.
________________________________________________________
24. That should be it. Play to test.
________________________________________________________

Tried once with a m2v done by CCE, and this didn't worked.

Video showed the same problems had remuxing with ifoedit.

With TMPeg vobedit method works, if GOP structure is the same using the template created with ifoedit.

Thanks for the guide, it was really helpful.
You might want to know about the following problem, though.

If the original VOB has multiplexing problems, neither VOBEdit nor IFOEdit work properly. The DVD plays with a little stuttering when the VOB is remuxed with IFOEdit, and with a lot of stutteding when it's remuxed with VOBEdit. It does play fine, however, if I use the remuxer that comes with ReMPEG2.

The multiplexing problems of the original VOB were detected by VirtualDubMod. When loading the VOB, it issued lots of errors:
"Anachronistic or discontinuous timestamp found in video stream 0 at byte position nnnnn (may indicate improper join)".
"Anachronistic or discontinuous timestamp found in audio stream 29 at byte position nnnnn (may indicate improper join)"

Another observation: although the subtitles were preserved, the closed captions (NTSC) were lost.

Best regards,
Cosmin

Hmmm...multiplexing problems? I've only tried the guide with my commercial DVDs and after a few, I've never had any problems.

Didn't use VirtualDubMod afterwards so I wouldn't have known if any error existed. Just previewed my backups and found no discrepancies during playback.

When I get the opportunity again to work on a DVD that has closed captions, I'll check to see if they were lost.

I am not surprised. I believe most of the commercial DVDs are prepared by experienced professionals, using expensive software, and they fully comply to the DVD spec -- no reason to run into problems with them. However, exceptions are entirely possible.

If everything goes well, you don't need to use VDMod. I used it to see what's wrong with my VOBs, then I discovered the problem with the original ones.

Hello, again,
I wanted to report that I tried to remux a M2V at a different resolution. While the original was at 720x480, I tried with 704x480 and 352x480, and it worked!

Well, it wasn't just like this. Thanks to the guys at VideoHelp.com, I found out that I had to edit the resolution info in the root structure of VIDEO_TS.IFO and VTS_0n_0.IFO, using IFOEdit. You can see this discussion if you are interested.

Pay attention to the issue of having subs at a different resolution than the M2V in the same VOB. I don't know if such a VOB is out of spec (any insight is appreciated), but my set-top DVD player (Panasonic RV-32) played it fine, while my version of CyberLink PowerDVD (4.0) showed the subs at double size, ugly and getting out of the screen. This was when the subs had full-D1 resolution, and the M2V had half-D1.

Mixing horizontal resolutions 720 and 704 was without problems. In fact, I recommend the 720->704 transition to anyone. Maybe not surprisingly, it saves a few percent in quality (or size, if you use constant quality) even when the video is padded with black bars. Although compression of luma may not be influenced by 8-pixel-wide bars, compression of chroma is: black bars yield hard-to-compress sharp edges right in the middle of chroma blocks.

Best regards,
Cosmin
