Video of Chair

Hey, this is just a short piece of time lapse of my chair on the rooftop. I haven't gotten a web cam yet but was thinking about camping out on the roof to get footage. It's not really anything now, but I like how the chair's shadow changes with passing of time. That's my boyfriend's dog Mia hanging around up there. I don't know why the video is such a small box, can someone help me figure that out? I guess it looks kind of neat to see a big black frame around it though. Ha ha, by the way I had to speed up this footage in FCP by literally 50000%.
