Hello All,

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:

Mac Pro
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

Any suggestions welcome.

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.

Hello Dave,

Right on all counts. I just installed a new Black Magic Card a few days ago, and I guess I couldn't help myself :-) Everything looks so nice on the big screen.

Anyhow, the shift zero does the trick.

Thank You

Dave Simpson
