Audio issue

I am editing down a QT HD trailer from 2 mins to 20 secs. When I place my edited footage into a final render comp it only plays the audio bed and the voice over is missing. When I do a ram preview in the edit comp the voice is there. What gives?
Why is AE removing the V/O and how do I get it back?
Are you able to separate the V/O and soundtrack in AE?

I'm sure you're aware that AE is a pretty lousy editing application and that just about ANY editing application will do a faster and better job. So I'll assume you have your reasons for doing this.
"When I place my edited footage into a final render comp it only plays the audio bed and the voice over is missing. When I do a ram preview in the edit comp the voice is there. What gives?"
I'm going to guess that it's the nature of the footage you're using, especially if you're using downloaded footage from iTunes. Read on...
Dave's Stock Answer #1:
If the footage you imported into AE is any kind of the following -- Native HDV, MPEG1, MPEG2, mp4, m2t, H.261 or H.264 -- you need to convert it to a different codec.
These kinds of footage use temporal, or interframe compression. They have keyframes at regular intervals, containing complete frame information. However, the frames in between do NOT have complete information. Interframe codecs toss out duplicated information.
In order to maintain peak rendering efficiency, AE needs complete information for each and every frame. But because these kinds of footage contain only partial information, AE freaks out, resulting in a wide variety of problems.

Use Quicktime Pro (best 35 bucks you'll spend in the next six months). Depending on you need for quality, use the Animation codec set to best quality if you need it REALLY nice, or use the Photo JPEG codec set to 50% if doesn't matter. If it DOES matter, you can always set Photo JPEG to 95%.
Don't forget to set the audio to something uncompressed like aiff.

[lyle Pascoe]"What would you use to edit a trailer with?"
Just about ANY editing software on the planet. What have you got? Use it.
Even that dorky-fanorky Steve Jobs iEdit, iVideo, Final Cut Express or whatever they call it would be better than AE. To get a consumer rig to properly with your HD trailer, you may have to jump through a few hoops to get HD to work in real time, but it would STILL be worth it.
Using AE for editing is a Right Royal Pain in the body part of your choice.
