Audio Drift Problem

I'm attempting to burn a DVD using the DVD burning function in Premiere Pro 2.0. The problem I'm having is that my audio is drifting just a little bit thoughtout the finished product. This project consists of lip synced clips timed to the originally recorded audio track, so no video is locked to the audio.
Interestingly, when I export to an AVI, there's no drift.

Does anyone have any background in this kind of problem--

Thanks,
Joe
 
Joe,
Can't say I've seen this problem. What's the bit and sample rate of your original audio and how does it compare to the audio setting for the preset you are using to burn the DVD? Is the audio shift slower or faster?

The sample rate of the audio clip is 44100 - 16bit - stereo
The audio setting of the project is 48000 - 32 bit floating point - stereo

Could this be the problem?
Also, I had started the audio track 2 frames from the beginning of the timeline-- will that make it "unstable" in it's position?

Thx,
Joe
 
Joe,
Is the audio running fast once you burn it to DVD? If so then it would sound like PPro is not properly conforming the audio for some reason. If you look at the audio file properties in PPro, does it properly see that it's 44.1k?

Try this - export just the audio track (File->Export->Audio) and in the settings, specify 'Entire Sequence' and a sample rate of 48000. This will ensure that the audio is conformed plus it will eliminate the gap in the timeline you mention. Put the new audio file on your timeline and mute the original audio track. The gap should not make a difference but I've only used the 'export to DVD' feature once or twice.

Dan-
Sorry I didn't get back to you right away.

The audio is lagging. I did the things you recommended. I output just the audio track at 48K, brought it back in, muted the first, made an avi, went to Encore and burned a DVD and it's still lagging.

Two things I know:
- The avi is fine
- The audio drifts in and out of sync on a DVD??

Joe,
Wow, I'm not sure what to say. You say the AVI is fine. Do you mean an AVI that you rendered with Premiere from the timeline is fine? It's when Encore burns it to DVD that the lag shows up? What are you viewing the DVD on? A DVD player or a PC or what? Have you tried it on more than device and the lag is consistent? Are you encoding the audio to AC3 on the DVD? What's the bandwidth setting you are using when you burn the DVD?

Dan,
Could it have anything to do with my MAudio Delta audio card? This thing has got a slew of software settings that I've never messed with?

Hey Dan,
You had asked if I had played it on a different player, which I had not. I've been playing it on a cheaper GO Video machine. I got home and played it on my high end Panasonic and it played fine. Sooooo, looks like that's all it is.

Question: can data be recorded too rich for some cheaper machines to process in the appropriate time? I hope I worded this question properly.

Thanks for your input.

Joe,
Does that mean you're seeing the audio lag when you're playing the DVD on your PC? I have no experience with MAudio cards. I would try your DVD on a real DVD player and compare the results.
