I'm trying to import from iPhoto to iMovie'11 and when I import it to iMovie'11 above my imported footage a redish/orangish line appears over all of it which I believe means corrupted. Yes, I'm using the latest updates, software, iMovie, and Macbook Pro Retina 13". I don't understand why I can preview the footage perfectly on iPhoto or when I import I check my finder for the .mov file and view it off Finder, which also streams perfectly, but for some reason is corrupted on iMovie'11? My footage was taken off a GoPro HD HERO3 with a Sandisk Micro SD Card that was transfered onto my mac's sd card slot. After importing to iPhoto I could view it perfectly, then I went to iMovie'11 and imported the iPhoto version to iMovie, then realizing I can't even watch the iMovie'11 version, because I believe it was corrupted. Yes, I've tried 2 times to delete the .mov files, and reimport to iMovie'11, but it doesn't work. I can stream it perfectly off everything besides iMovie.
MacBook Pro (Retina, 13-inch, Late 2012), OS X Mountain Lion (10.8.2)
