GH2 airport timelapse

I love the activity in this timelapse, shot at Philadelphia airport on my Panasonic GH2. The window we were looking out at was the perfect frame. My Slik tripod was checked in so I placed the camera on the radiator on the wall. A very nice timelapse except for two frames that went nearly black and I have no idea why...
Since I don't have Quicktime 7 Pro installed on my Macbook Pro, I had to find an alternative to make quick 'n easy timelapses. Well, in no time I found Time Lapse Assembler, a completely free, very simple program that makes timelapsing a breeze! I love it. Who needs Quicktime 7..?
