Audio in 625/50 DVDs

JohnI wrote on 3/14/2003, 5:03 PM

I thought that the audio standard for 625 DVDs was MPEG layer 2. However it seems that DVDA offeres only uncompressed and Dolby AC3. Am I correct for 625 based audio or not? Certainly DVDA seems to want to recomprocess my DVD compatible MPEG audio from VV4 from layer 2 to AC3/Uncompressed. Can someone clarify please? Thanks John I

I wouldn't say that MPEG-1 layer II audio is "THE" standard for PAL 625/50 but all PAL players have to be able to play PCM/AC3 & MPEG-1 Layer II audio while NTSC players only have to support PCM & AC3 (while a growing number may support MPEG audio)

I am in Europe and use AC3 in my projects as opposed to MPEG.

Thanks for the clarification. However it does seem strange that the VV4 DVD compatible render template compresses to mpeg layer 2 (with no other option) which DVDA does not accept and insists upon recompressing to AC-3 or PCM. I think SF need to to a consistency check and improve the integration between the two products!!!

I just noticed that too. This is unacceptable sloppyness on SoFo's part. You waste hours , actually over a day rendering the collection of videos you want to burn to a DVD in Vegas and now I see a whole bunch of yellow warning flags because of the AC-3 issue and DVDA is telling me its going to recompress everything?

So now what, I wasted the better part of a day messing around, I finally think I can burn a DVD and now this problem on top of the three major bugs I found.

I've about had it with DVDA. A cheap little application like Ulead's Movie Factory didn't have any problems at all and processed files right away. All the mickey mousing around for what is suppose to be a "professional" grade application is getting on my nerves.
