[Techtalk] Compressing ogg file

[Val Henson]

Hi folks,

I successfully recorded my talk at SVLUG about the recent FLOSSPOLS
gender study, but now I'm stuck with a 46MB ogg file (it's an hour
long).  This is way too huge to ship around the net.  What are my
options for compressing this file?

I also would like to edit the recording and my slides together into a
movie, so that the relevant slide is automatically showing.  Any
suggestions for how to do that?
