ProPreseter and a Free Motion Background

Are you a Leopard user? You just got a free motion background for Pro-Presenter. We were sitting in production meeting last week and I had my laptop up and running. About midway into the meeting my laptop kicked in the screen saver and Stephen loved it and thought it would be a cool motion background. He asked if I could make it work for a song on Sunday. I started running different ways through my head of how to capture the screen saver to a video and make it into loop. I forgot about it until Friday night and then I started working on it. It took me a little while just to find where in OS X the screen savers were stored. I knew that OS X had started using Quartz Composer files for some of the screen savers and the one I was using, Arabesque, was a Quartz file. Quartz happens to be an integral part of Quicktime and the QT player can play Quartz files. Most of the time, if QT can play it then most likely Pro-Presenter can play it as well. Sure enough, I just dragged the file into the background library and it worked. Now we have a new background and it was under my nose all of the time. By the way, the screen savers are stored in /System/Library/Screen Savers.

Quartz Composer is a very powerful compositing and graphic creation program. What is even more interesting is that Quartz files are dynamic. Arabesque is a random composition and when you used in Pro-Presenter it is random as well. This could be good or it might not be what you intended. I’m very interested to learn a little more about Quartz and see how we can use it in media ministry. A few ideas that come to mind are maybe a news ticker across the bottom of an announcement loop or a countdown clock that is longer then 99 hours. Let me know if you come up with some Quartz Composer ideas.
