George Bush shows President Barack Obama The White House

In celebration of inauguration day, we've finished Obama's tour of the White House in episode 3 of Pennsylvania Avenue (above). The new segments of the video were filmed in front of a green screen, and inserting backgrounds was easy with the help of Final Cut Pro's Chroma Keyer video filter.

With each new episode, we've increased the sophistication of the setups. We're now using a PD-4 timecode DAT recorder for sound and using multiple 1K Arri lights. The lights have made a huge difference - you can really see the difference between the flat lighting we used in the map room and the dirctional lighting we used for the new segments.

Hope you enjoy!
