layering in sound

Ok I've made a slideshow. In the first and last frames I have sound effects. In the other frames I want a quiet background guitar track I have.

When I put the music in via inspector its on all the slides and runs over the sound effects. I don't know how to make it only on the other 10 slides. I know how to put it into one slide but if I do that with all of them the music will be starting over on each of the 10 slides.

I read online someone exported to desktop as quicktime movie. Then imported to imovie. That seemed like a great idea and I was able to put the music exactly where I wanted it. However when I then finalized the movie with the added sound and then saved it to the desktop via quicktime. (in .mov format) Then I uploaded it to youtube (which is where it needs to go) and the quality of the photographs in the slideshow and the text is seriously degraded. I'm a novice at all this but I'm assuming it was either how it was saved in iMovie or just the few saves that degraded it.

Is there some other way for me to put in a soundtrack on a 12 slide slideshow so it is not on slide 1 and slide 12 but plays on 2-11? Or is there some other way to save it in imovie so it doesn't degrade the quality?

Thanks

Of course its degraded, that's you tube quality.

Create the sound track in an audio editing application, Audacity is freeware. Time the audio to match the video content, keeping the track silent where you require it. Add the sound track to the audio well in

I just want to be a little clearer. If I save the slideshow in Keynote as a Quicktime and then upload that to You tube (without the soundtrack but still with the sound effects I have on the first and last slide) the quality is excellent. It only degrades when I put it in imovie, add the soundtrack and save it again.

I thought about the idea you had Gary a few hours ago but I don't know of any audio editing software, I opened garageband to see if I could do it in there but realized it would take me forever to learn how to use it. I'm going to try Audacity and see if its any easier, but this could be a great work around.

What I need is 13 seconds of silence on the soundtrack before the music starts and then for the entire music track to only be 55 seconds long. If I can figure out how to do that this will work perfectly. Keep your fingers crossed and thanks for all your help.

Plenty learning material available if you search 'Audacity Tutorials' in Google
