Adobe Media Encoder CS4, persistent audio sync issue
 

Hi, I'm facing a very frustrating video/audio sync issues when using the Media Encoder.
Doesn't matter what output format I select be it H.264 or WMV, the audio will slowly drift out of sync from the video. By 20 minutes or so, it becomes very apparent with the video trailing the audio by about 0.5 seconds (ie. audio gets faster than video).

This also happens with truncated clips. For example if I only choose to encode between minute 20 to 21 of a 60 minutes, the sync issues will be just as bad.

Wierd thing is that when using other applications such as Total Video Encoder, I never face this problem. Any help of pointers to possible solutions will be greatly appreciated!

Did you ever find a solution to this? I'm having the exact same problem with CS5... no export option is able to sync audio property over 10 minutes.
