Using MPEG with AC-3 Audio

subsurface wrote on 11/23/2004, 5:02 AM

I'm juist experimenting with a video (MPEG) that has an Ac-3 audio soundtrack. When I immport this into DVD Architect, the video seems to open just fine, but no audio track is showing. Am I missding something or does this program not handle AC-3 audio?

DVDA handles AC3 just fine. The requirements for having DVDA bring in the audio atumatically are that it be: 1) rendered in a seperate file, 2) the filename be exactly the same name as the MPEG (not the extension obviously), 3) both files are in the same directory.

In the event that DVDA does not being in the audio automatically, simply use the object properties and select the specific audio file.

Thanks for the reply Scott

What I'm trying to do is re-author an existing DVD. It's two individual music concerts that have no 'proper' menu and have no track splits/chapters. I've transferred the video_ts folder onto my hard drive, I've then merged the vob files for each of the shows, then I've run them through Womble MPEG Video Wizard to demultiplex the video and audio.

All is well with that, and DVDA is accepting the files just fine now they are demultiplexed, but DVDA is reporting the size of the project to be almost 6gb in size, whereas the files themselves only total 4.2gb.

Any ideas what might be causing this? I've created a couple of discs using MPEG's with LPCM audio , and they've loaded just fine and reported no increase in size from the original files.

Hang on!!!

Think I've found out why..the properties were shoing a PAL project 720x 576, whereas the one I was creating was NTSC, and it was going to recompress the video.

I think I'm sorted now!!
