Way back when, for linux.conf.au coming to Melbourne in 2008, I edited together a promo video for it. IIRC the raw video was shot by Kelly on DV tape, imported in and I got a CD of some massive 400MB MPEG file of a bunch of questions. Using Cinelerra and some graphics package that I forget (very early Inkscape?), I managed to get this done in 2006. I understand things are a bit less segfaulty these days.
See it on YouTube or download the Ogg Theora video.
Amazingly enough, this is the last time I actually did any video editing.
You should also go to linux.conf.au 2011 in Brisbane this upcoming January.
