no audio

[teepee]

Hi all,

When I try to burn a dvd from an mpeg made up of an ac3 file and an m2v file the burning software won't recognise the audio in the mpeg.

I got the streams off a DVD via smartripper and used tmpegnc v3.0xp to create the mpeg.

I can play the mpeg in wmp, power dvd etc and the audio is there in dolby digital format.

I'm using Ulead Videostudio 9 to do the conversion and burning.

Ulead tech support say that videostudio9 does not have a licence to input dolby digital/ac3 hence no audio as its unsupported.

They also didn't deny that Videostudio9 is a bit shaky, lots of general error messages etc, which I've experienced also.

Bitching aside, I tried the same process using Nero 6 Reloaded, with the same problem. No audio. Well, the error message was 'could not create dvd structure' but in the log file it reads 'unsupported audio format'

I then recoded my mpeg in tmpgenc to mpeg 1 layer 2 audio, thinking to get around the Dolby licence problem (if that's what it is)

Bu it makes no difference. Still no audio.

Either I am doing the ripping and/or encoding process wrongly, in which case please set me straight. Or, this is an actual conflict which hopefully someone has a fix for.

There's a couple ways around the issue depending on what you need the end result to be. If all you need is a DVD spec compliant video compilation. Simply load your video and audio stream into Muxman, the output will be ready to burn with Nero, etc.

If you need to further process the compilation, then you should look into converting the .ac3 audio into .wav with BeSweet + BeLight or BeSweetGUI or Goldwave or similar, which VS9 shouldn't have any trouble with.

Ok.. I used remux and that very easily created all the vob files etc but when it came to adding files in Nero, Nero could only see the first vob in the series (vts_01_1.vob). I thought it would automatically pick the rest up but it doesn't so I can only burn the first 2 mins of the film. VS9 wont pick up vobs so I ran up against the wall there.

On to converting ac3 to wav..besweetGUI looked good. a 5 step wizard followed by a go button. The go button opens a window asking if you want to save a log file. Whether you say yes or no, pressing the go button just opens a blank text file. I don't know what to put in the text file to start the conversion.

I moved on to Goldwave, did get a wav file and subsequently a succesful mpeg that VS9 can open and play with audio so all good there. Unfortunately the inclusion of the wav means the mpeg is now well over 5Gig and VS9 throws up an error (again) trying to convert it using the 'fit and burn' option. error msg is '4101: convert step got some problems'

I'm currently running the mpeg back through tmpgenc at a lower bitrate (6000) so that may well eventually solve the issue so thanks!

But for expediency in the future I could do with figuring out besweetGUI and the vob problem. Can you tell me whats going on with the textfile popping up in besweetGUI? And why won't nero pick up the extra vob files?

[Taelon]

teepee, Not sure about the BesweetGUI trouble, I use 'BeLight' and haven't seen anything like that.

I'm not clear on what you mean by the extra .VOB files. I thought that Muxman 0.14g (the free version) would only output one .VOB file, unless you are running it multiple times, but then I've only used it for short clips. If you have a bunch of .m2v files you want to string together in Muxman use the Add button instead of running each one as a seperate process.

hope this helps

@teepee - have you got the various dlls required for BeSweet? It occasionally pops up a message saying you need such and such, so you go to the site and DL it. New users to BeSweet do tend to use the BeLight GUI, as Taelon advised.

As for your VOB set, 2 things come to mind. Are all your DVD files in nero's red folder? And have you done a mock strip?

Taelon, I didn't try belight but eventually got a wav from using PX3'sAC3toWAV. Since i'm using muxman I will try using the original ac3 file as I only needed the wav originally to make a hassle free mpeg.

"I thought that Muxman 0.14g (the free version) would only output one .VOB file,"

That's the version I have but it outputs 5 vobs (1_1 to 1_5) plus bup and ifo files. Pretty neat. Muxman tends to crash on me tho if I run other programs or press keys even but eventually I got a pile of vobs that Nero accepted so I guess previous failures were down to an incomplete muxman session.

Blutach, Not sure what a mock strip is so I guess I haven't done one..but job done anyway thanks next stop shrinking..

Ok that makes sense if your source .m2v is over 4 GB. It's amazing what the authors of these freeware programs have done when you consider they often run circles around commercial software.

Glad to hear you found a working solution for the roadblock that you had using VS 9.

For a mock strip - see my signature in my previous post.

Glad things worked out. Muxman is a work of art, isn't it. It worth joining www.mpucoder.com to get the latest (0.15k is the latest beta I think)

Here's the release log - http://www.mpucoder.com/Muxman/advance/release.txt
