DVDA 2 Re-renders/compresses audio sometimes
on occasion, DVDA 2 will tell me that it has to re-reneder (or compress) audio on track 1 (or what ever).
I just let it do its thing, but can anyone explain why this would be – when it is already rendered as an AC3 file?
Thanks’

Perhaps the MPEG file also had audio and it’s using that instead of the AC3 file?

Wow… ED, you may be onto someting,
if memory serves me (less and less as I get older) I seem to get this when I “apply effects to” audio tracks (EQ) – or perhaps filter or open audio tracks (or copies of audio tracks) in the wave editor (coold edit 2K) or copy or duplicate tracks. which then vegas often makes a “copy” of the track
Is there any thing special I should do to my audio renders to make sure everything is “as it should be” – or anyting to prepare int the time line?? -perhaps prerender the audio???
Old habits are hard to break and I really needed to keep production up so I still relyed on much of my editing on media 100’s (for the sake of learning curve) but I’ve tried to use vegas more and more lately so I perhaps have the cart way ahead of the horse in terms of “jumping ahead” with procedures without clearly understanding what I’m doing. (the program is proving to have some really strong points)
Any insight on the fact that one “monkeys” with the audio tracks and then DVDA2 ends up having to recompress something – when I do render for DVD i usually take these steps: 1. select all 2. render mpeg2, and then the AC3 at -31 db as suggested.
thanks all!

I was just thinking that the MPEG2 preset you used might have included audio and DVDA didn’t automatically pick up the AC3 for some reason. That’s why I always double-check to make sure the AC3 is being used.

You look at the properties on the right side

Wayne, make sure that you’re using the DVD Architect NTSC video stream to get a video only clip. Selecting anything else will give you either an m2v file or an mpeg file with audio.

As Mike says above. Then go back and render to AC3. You should then have two files. Your video and the audio. When you drag the video into DVDA-2 the audio will automatically follow.
