#   The videos were made with QuickTime on OS X, default
#   settings, except with the internal microphone turned off.
#
# QuickTime produces H.264 codec quicktime vidoes (*.mov).
# QuickTime does export into other formats, but they are all H.264.
# For cross browser compatability (as of Feb. 2012), one must
# provide H.264 and either Theora or VP8 (webm) codecs.
# 
# Aim for  
#         H.264 codec with mpeg 4  (*.mp4)
#         theora codec with ogg    (*.ogv)
