Is it possible to merge audio/video in a trimmed Adobe Captivate video demo?

When trimming the video, it creates "pieces" (for lack of a better word) and breaks the audio up, as well.  I need one audio track to export, because when I attempt to add a video demo to a Captivate project it jacks up the audio every time.  The only way I've found to fix this is to export the audio and manually manipulate it after re-importing into the project.
