How do you turn Open Office Presentation files into a Video?

I am using Open Office 3.2, and I was wondering if I can turn my Presentation slides with Pictures and Music into a single Video file, like a .AVI or .MPEG. Is there an easy way to do this? If not, is there a free open source program that can convert the .ODP files into a .AVI or .MPEG or other widely used and supported Video file? Thanks in advance for you help!
