DVD SP3 Audio File Problems at DVinfo.net

Dave Perry · March 28th, 2005, 03:51 PM

I've been using a.pack to convert all of my audio to AC3 in order to save space and make more compatible DVDs for various palyers. All has been going well until I decided to put a short intro movie in a blank menu set to First Play,then it would target the Main Menu.

I made my m2v and AC3 files but when I started the Build/Format, I got an error message saying all audio had to be the same format, which it was. All audio used in the project was AC3.

After trying a few adjustments and re-encodes of my intro movie to no avail, I decided to just use an aiff like I used to do. It worked even though at this point I no longer had all the same type of audio files.

This defeats the purpose of using the AC3 files to get better set top compatibility when I have AC3 files and one mpg audio file for the intro.

Anyone know why I would have gotten the error message?

It sounds like this message is not complaining of using different
file TYPES or encoding formats, but SAMPLE formats, like:

- sample rate, 44.1 or 48 KHz etc.

- bits: 12 or 16 bits

Rob,

I figured it out. I was using a .mov file for the menu background that had an audio track. Although there was no oaudio on the track, the fact tthat it was there is what the issue was.
