In this tutorial, I go over how you can add sound effects to Final Cut Pro 7 WITHOUT having to go into Soundtrack Pro. It's pretty simply, and allows you to add effects and audio without having to finalize your video before working with your audio.
This video is recorded DURING my high school media class, so you will hear sniffles, doors, and all sorts of interruptions. Hopefully those distractions will not ruin the content. More videos and other tutorials can be found on my website at http://www.weisbrodimaging.com/classes/
