UPDATE: Spring 2013. SRF reader Jessica Barr corresponded with me in 2012 about how users of more recent versions of the Mac OS (10.6 and higher) might have issues with the Automator script below because QuickTime 7 is no longer the default movie Mac OS movie player. Jessica kindly revised the automator script and offered it to me so I could share it with you.

(By the way, from my limited testing, it appears you still need QT Pro 7 — which is still sold as of May 2013 — to run this script. Quicktime X, or whatever it’s called, can loop, but you can’t save a movie as one that loops. And Automator’s loop instruction in its “play movie” actions don’t work reliably. )
Read on for the full instructions…..
Original Post from 2008:
Apologies for the long post title. This is to help anyone searching for such a thing on the internet.
This post will explain how to create a video that plays full-screen and loops repeatedly on a Mac. Looping full screen video is useful for, among other things, kiosks and video installations. If you want to cut to the chase and learn how to do this, skip down. Otherwise, I’ll offer a few words explaining the reasoning behind what I did.
Ashley Maynor and I recently put up a small video installation near the offices of the Arts Council of the Blue Ridge. The installation was done as a gratis piece of temporary public art, so we needed to keep the budget as small as possible.
In our case, this was a three channel installation — that is, we had three different videos playing simultaneously on three different screens. The screens were going to sit next to each other, so we wanted some uniformity in presentation. Video projection wasn’t an option — the space was too tiny for projection. (It’s basically an empty downtown shopwindow.) So we needed televisions or computer screens.
We didn’t have three identical televisions, but I did have three identical old semi-working iMacs sitting in a “junk” closet at Virginia Tech. So I borrowed those.
Regardless of whether you use a television with a DVD player, or a computer and its video monitor, for this sort of thing you might burn a DVD that loops. That’s a perfectly fine solution, but the DVD player on one of the iMacs was broken. Also, there might be solutions out there for having a DVD player and television power up and down automatically, but I know it can be done (and know how to do it) with a computer.
So how to do it?
I decided to create a simple Automator application that could be used to automatically screen a QuickTime movie in full screen mode when the computer was booted. I also automated the startup and shutdown of the computers so that the installation runs during prime hours downtown, saving power in the wee small hours of the morning. Details on how to do this after the jump.
