At any given conference you'll have speakers and presenters who get up and use some sort of slide presentation. There's also usually a video setup which is documenting the conference and possibly giving attendees alternate angles. At MacTech, sessions were recorded and mixed with graphics live using BoinxTV and a few additional tools.
Check out the video below as Oliver Breidenbach (from Boinx) walks us through the equipment used for MacTech presentations and live video archiving.
