Audio Sync during long playback
Using Avid Express Pro 4.6 with Mojo.
We’re trying to play out a 2 hour program to DVD. (Recording playout to a recorder, not encoding) It’s fairly straight forward with only a couple of edits involved.
Problem is after the first edit (which is about 1 hour and 10 minutes in) the audio loses sync quickly. This only occurs when the Avid plays all the way to that point…if you cue it there and then hit play, the sync is fine.
We’re using the DV 25 codec and have plenty of media space remaining.
Is a two hour playback just too much to ask for this baby Avid?
Any ideas?John Watts

A couple ideas…
for starters, when outputting to a stand alone recorder VHS or DVD I like to do a digital cut preview – no deck, hit the yellow button. This allocates the system resources necessary to ensure locked 30 fps playback, as well as no interruptions from screensavers and the like. From what I understand as we’re just playing the sequence in the composer, the app is always looking down the timeline and loading what is coming up into RAM. Maybe after over an hour, the software only Xpress can’t load in the new clip quickly enough…?
The other thought is if the Xpress 4.6 is on a mac, I’ve read that having your display set to a non-native resolution can cause sync issues, but what I’ve read you’d notice it from the get-go, not as far in as you indicate.
