I just played around a little. You can export a Keynote to a QT movie. All your transitions and effects appear. You can choose to do

manual or automatic advance. In short, anything your Keynote does, the exported QT seems to do. However, I couldn't figure out how to do a

Ken Burns effect in Keynote on the slides.

yes - export it, but be patient. It takes a while.

thanks! I played with keynote but couldn't figure out ken burns effects... iPhoto 09 supports this tho, so I did it there

I don't think there is a Ken Burns effect in Keynote. You might be able to simulate one with builds. I haven't worked with new KN

might be in actions. Haven't checked there too much. Ask Keynote help.

I tried to find it in keynote help and couldn't - I don't think it supports ken burns style effects
