Hi
I'll probably need an hour, but damn, I already hear myself cursing during cutting of the video -_-
there's probably a limit set by FOSDEM, max 1hr talk, i'm not sure but hey, i have some ffmpeg commands which you can speed up audio and video, and still stay sync'd - it does have the disadvantage that if you naturally speak fast anyway, people can barely keep up :)
My natural speech is already very fast and contains a lot of complex concepts, and people naturally already have trouble following. I don't think speeding up the speed of my voice will be helpful :-)
Cheers -lev
