1. Re: Exported .mp4 and FlipFactory audio sync problems
John T Smith Nov 4, 2012 9:36 AM (in response to taz291819)Since you mention WMP, I will presume you are on Windows
So, use http://mediainfo.sourceforge.net/en to analyze the DETAILS of the CS5.5 and CS6 output files to see what is different

2. Re: Exported .mp4 and FlipFactory audio sync problems
taz291819 Nov 5, 2012 2:50 PM (in response to John T Smith)Did somewhat of what you asked. I exported the same show in CS6, one using the H.264 preset, one using the H.264 BluRay preset. The H.264 preset one drifts out of sync after FlipFactory, the other stays in sync.
Here are the media info specs for each file (I did use different bitrates on the two, but that shouldn't cause an issue):
