View Full Version : Simple muxing of video, audio and subs: it can go wrong...

Well,

First off: I'm not an advanced video-editor, and this was my first project where I would include subtitles in a DVD...

I looked through the guides and decided to give IfoEdit a go after:
1. having stripped the VBR .mp3-audio from the source-file with Nandub;
2. having encoded the XVID .avi to an .m2v with TMPEGenc;
3. using BeSweet I transcoded the .mp3 to both .mp2 and .ac3.

Everything went like a charm, but viewing the result with WinDVD after IfoEdit (both 0.96 and 0.971) was always without sound. I got no fatal errors in the log-file, but I did receive a warning that it had encountered buffer-underruns.

So I tried to view all the elements with MPC, and the audio-files were perfectly OK!!

I started doubting IfoEdit and looked through some more guides and the forum... Results (with the same files):
1. Muxman 0.5 just quits when I hit the 'start'-button (several tries), and wouldn't accept my .mp2-file, so that I had to make an .ac3-file;
2. DVDmaestro displayed the wrong length of video/audio, so that the subtitles didn't fit anymore - I never tried authoring with this package, because it just seemed wrong and I didn't have that much time to fiddle around...
3. DVD-Lab Pro: same as IfoEdit: video and both subtitles are perfect, but no audio when viewed in WinDVD or in a standalone DVD-player. When played in MPC, I get audio but no subtitle-menu (first subtitles are shown and cannot be turned off).

I'm thinking there's something wrong with the source? Or is there something I'm doing wrong? I have followed the guides and searched through the forum, but I didn't find an answer to my problem...

Zl.

mp2 is acceptable for NTSC DVD. It's just that it is not required to be supported by the players. My player does support it, and I tested it in MuxMan.
I can't speak for the other programs, but MuxMan should have told you why it rejected the file. And I know of no condition that could make it quit without a message, at least in the log.
