The source machine is configured to output a 1280x720 viewport locked in the centre of a 1920x1080 screen, thus providing a "viewfinder" allowing the operator to see the area around the scene being captured. (You can dispense with this if you wish, in which case you simply need to set up a 1280x720 screen and clone it. In which case all the special NVIDIA control panel requirements and the need for XP all suddenly go away. However... I really can't believe how useful that extra room in the viewfinder is!). The tricky bit is setting up the viewport. Well, actually, ''all'' the setup is tricky. It starts with setting up a dual-boot machine and goes on from there.

The tricky bit is setting up the viewport.  
The video capture machine is set up to capture video from the source machine(s) using the Blackmagic card(s). Wirecast is used both as a "gearbox" to change the framerate to the desired output and to aggregate the required audio feeds. It is then used to record to disc at the target Treet workflow framerate and format. The tricky bit is the audio, by the way. Everything else is pretty easy.
