Im about to give up :( audio is wacked!!

[Swole_Dude]

Ok, 1 year ago I never had one problem and now first time back doing this I cant get this working. I have pirates of the carribean and I extracted audio with virtual dub as .ac3 cause thats what the video is. I took headac3 program and converted it to wav. I then coded the xvid/divx using svcd template and used the wav file that I had for audio. When I play the movie it works like a charm not one problem, but when I use merge and cut with tmpege and cut sections out so it will fit on a cd, each section at the very it looses sound. Does anyone know why I loose sound at the very end of each section. Only happens when I merge and cut with tmpgenc. I have never had a problem like this before so any help would be much appreciated. Thanks in advance.

Hmmmm...Is that on DVD already?

[Swole_Dude]

No its not going to a dvd, it was a xvid or divx file, which I then coded into svcd.. I'm wanting to burn it to 3, 80 min disc, but with tmpegnc merge and cut once I split the files up, I then lose sound at the end of each section.

I have pirates of the carribean .

I didn't know that (see above) was released on DVD already.

I scanned the file with VD first and it found no errors in it what so ever. The help files for tmpege isn't what I'm looking for it says convert to .wav and use it as audio source LOL that is what I did. Just incase you are confused i'll go over it again. I have pirates of the carribean xvid/divx, I scanned it with VD no errors. The file uses ac3 audio, so I used virtual dub and extracted the audio as potcc.ac3, I then opened up headac3 and converted that file to potcc.wav. I then opend up tmpegnc and loaded my xvid file, then loaded the potcc.wav as the audio source. I then coded the file into 1 big svcd file. Now the file as one big file plays fine no synch probs. no jerks, and the video is perfect. Where I run into problems at are as follows. I'm going to cut sections out a total of 3 to fit on each section on each cd, so a total of 3 cds. But when I cut each section from the one big file at the end of each section like the last 9 or 10 sec. I lose sound on each section and I'm not sure why. The audio and video have the same time in minutes and seconds. Do you know why this is happening?

Yes. Cutting a mpg is always tricky, and I've never succeded, no matter what application I've tried. Knowing this, I simply encode mpgs that will fit on my medium (CD or DVD). Mainly, this can be achieved in 2 ways: either by frame serving from VirtualDub and selecting different ranges, or use the source range feature in TMPGEnc when not frame serving.

I found the best way for me to cut mpg files was to demux with tmpgenc and then run the files thru bbmpeg putting in the start and end length of time for each part to be muxed.

[Swole_Dude]

Well what ended up working for me was just code out each section by frames at a time, then multiplex it and it works. For some reason it still had errors after then encode so the multiplex fixed it. Peace.

have u thought about splitting the files before u convert them to mpeg ?
