Audio Sync Issue
by Dave Simpson on Nov 14, 2012 at 7:24:09 pm
I am creating some Station Ids in CS5.5. Something I have done many times before without any issues. When I do my RAM previews the audio is about 3 or 4 seconds ahead of the video. I searched the forum and found out mp3 and other compressed files can give AE some trouble so I mixed the music and voice track and rendered out a wav and a Quicktime movie version. Both still have the same issues.
The odd part is when I just do audio preview (work area) or audio preview (here forward) it seems to be fine. I did an edit/purge all but still have the problem.
It's a bit of a pain when I am with the client and have to explain that the voice actually does come in when the logo appears etc.
I am using CS5.5 on the following machine:
Processor Name: Dual-Core Intel Xeon
Processor Speed: 3 GHz
Number Of Processors: 2
Total Number Of Cores: 4
L2 Cache (per processor): 4 MB
Memory: 16 GB

You're probably doing the RAM Previews at full resolution and frame rate, right? And you're probably working in HD, right? You might even be routing your previews through a capture card to a video monitor.
Try the most common previewing trick: instead of hitting zero on the numeric keypad, hit shift-zero to preview every other frame. Or chenge the resolution to half. Or both.
