Freezing AMV- "We're All to Blame"

Been working on this AMV for nearly six months, reason being is that I own a Mac and used the application iMovie. There were issues with the clips here and there as they would tend to freeze(no pun intended) making it difficult for me to time the scenes together. Also, looking for a song that portrayed the AMV was extremely difficult and realized that Sum 41's "We're All to Blame" fit perfectly. First AMV I've ever done, intend on making a Deadman Wonderland one eventually. = w=b
