Adobe MPEG Encoder audio compression: AC3 and PCM

[cheerful]

I am a newbie and here is my question:

The encoder will output PCM by default, which is a pretty big WAV file. I heard this file is NOT compressed. Is that true?

The other option is to compress with MPEG-2. I've heard about people talking about AC3. Is that the same? If not, the MPEG-2 compitable with DVD authoring software? How do I produce AC3 file?

Thanks!

Yes...



" MPEG-2 compitable with DVD authoring software?"

Yes...

Is MPEG-2 audio compression good? Can a DVD player play a DVD made from MPEG-2 video and MPEG-2 audio?

Do you have any website link that talks about these stuff? It is really confusing to me.

Thanks a lot!

MPEG-2 audio to which you are refering is actually MPEG-1 layer 2 audio which is the audio standard for VCDs, and it doesn't come even close to AC3 which is also known as Dolby Digital.

I'm not sure of how to encode AC3 but I believe that you can use besweet to do that. Try searching on www.google.com to see if you find something. If your source is from DVD then you probably already have AC3. Try searching this forum as well maybe there is something about that too

Good luck
