no sound from merged/converted files

[agent222]

I have had some xvid.avi files that I have merged using VirtualDub, and, another program (1 one each.) I then took the merged files, and since NeroVisionExpress wouldn't work on them, ran them through TMPGEncoder, and, then through TMPGEnc DVDAuthor.
Burning the DVD files was done through NeroRecode.

In both cases, the video looked fine, but there was no sound.
Besides the editing programs, the only other change I made was checking the "use orginal sound file" option in DVDAuthor. Again, in both cases no sound.

Is there some setting in either the editing programs, TMPEnc, or, TMPEnc DVDAuthor, that I've failed to set/reset, or, is there probable reason for this happening?

Thanks to any, and, all who answer.

Audio when playing the AVIs?
Audio after "running them thru" TMPGEnc?
Audio after authoring with TDA?

99% sure the problem is when you appended each segment in VirtualDub. Encode each file separately to avoid audio problems. Once done join each file seamlessly in TDA. Job Done. I think you'll find that it is now ok.

geeman;
let me make sure of what you're suggesting;
convert each file in TMPGEnc, then merge them there, and, then convert to DVD in author. afterwards can burn it to DVD with author, or, similar.

No.

convert each file in TMPGEnc.
then author to DVD in author, putting them into the same track if you want them to be joined.
afterwards can burn it to DVD with author, or, similar.

No, as already mentioned. Encode disc 1 and then encode disc 2-both in TMPGenc (Just the Encoder). You now have 2 Mpeg2 files all ready to drop into TDA. Open up TDA (TMPGenc DVD Author) go Add file (disc1) click Ok (add chapters if need be) then go Add file again for disc 2. Job Done. TDA will output the 2 discs as one continuous file and if the breaks on source files were exact i am confident you won't even see where they were merged. Now burn to disc (shrink prior, if necessary)

I've found that you need to delete the chapter point that TDA automatically creates at the beginning of the second clip to stop a slight pause from occurring when it gets to this point in playback. YMMV I guess.

[agent222]

if I use the method geeman suggests, how do I delete the chapter point jimmalenko belives might occur?

Click on the chapter point and click the delete button.

[thegeeman]

Yes, Jimmalenko is right. It doesn't happen 100% of the time but it does happen more often than not. Simple to do though. Dont be put off by the amount of text in my reply, i just go on a bit.

This is from MEMORY now cos i dont have a m2v file to load to walk it through first!!!!!! Please no ribbing-thanks, lol.

When you add first file you will then see a tab that says chapter cut edit. Click on it. Now click on 'ADD' down at the bottom right. It will prompt you to insert chapters and it gives approx 3 or 4 options-i usually go with a set no. of chapters but thats upto you. Once done click OK.

Now Add 2nd file and do the same except that when you do chapter cut edit on the 2nd file make sure that your chapters are inserted differently, eg. insert at specified time code, at so many minute intervals etc.

Possible Alternative:-Now i do not know if this works or not because i haven't yet tried it. This is for 2nd file added only-When you've added your chapters you will see on the right hand side a no. of thumbnails corresponding to the no.of chapters selected-i'm not sure if its possible to edit the first chapter point of the 2nd file added just there. I'm sure there are 2 'edit' 'delete' boxes if memory serves me right-apologies if not (alzheimers!!!) Give it a try-you wont break it. I hope its helped.

[thegeeman]

Here's me typing all that lot and Jimmalenko nails it in half a sentence!!!I'm sure there was a delete option but my brain is totally fried-its almost 2am here now. At least you have the hang of insert chapters now at least.

Thanks jimmalenko, only having a laugh.

[jimmalenko]

Add both files to the one track. Click on the Edit button of the 2nd clip:




Go to Chapter Cut Edit:




Select the first (top) chapter point, and click the Delete button.




Click OK.




The chapter point is gone !




Now just add the chapters every 10 minutes, or auto-insert 10 chapters, or whatever.

I am becoming fustrated. I batch encoded two files, through TMPGEncoder, setting the file size so that both would fit on one DVD. I then used TMPGEncoder DVD Author to create the DVD. NO SOUND! I have installed the AC3 filter, though if I check files through Video Inspector, it says I don't have it. The orginal xvid.avi files, when played through Windows Media Player does have sound. What am I doing wrong?

[mats.hogberg]

Extract the audio out of the AVIs to wav first. Easiest is to just load the AVI in Goldwave, Save.
Play the resulting wav to make sure it's ok. (This is a good practice to test play after every step - no need to find something's gone wrong early on in the process when you pop the DVD in your player!)
Then use AVI as video source, wav as audio source in TMPGEnc.
To make doubly sure - encode just a minute, then abort. Play the mpg. Does it look good? Does it sound good? OK, encode the whole lot.

Simply, you don't mention what is your original audio in xvid.avi's

[agent222]

the audio tracks are whatever the audio tracks were when I downloaded the files. In the case of the files I'm working with at the moment, the orginal sound was TV audio tracks, which may, or, may not have been modified when uploaded.

[agent222]

I have just tried to play one of the extracted .wav file from the batch encoded files. nothing. does this mean there is a problem with TDA?

(What I mean by extracted, is that when TMPCEncoder does it's job, it produces two files m2v, and, .wav from the orginal .avi file.)

[NormaJ]

It seems there is something wrong with the audio into your avi, that Tmpgenc can't deal with. Probably ac3 audio, or vbr mp3...

This is the reason why mats has told you to extract the audio directly from the avi using Goldwave. You can also use ffmpeggui. But give the audio job done to Tmpgenc.

No, most likely in TMPGEnc.
When someone asks you for what type of audio, he/she mostly means "what type of audio codec" here. Use GSpot to find out, and if you can't make heads or tails of the output, just make a screen shot and post it.
Again, extract audio to wav before you start TMPGEnc, and verify it's OK before proceding.
