As you can see in this video quicktime isn't playing correctly!
Playing the video elsewhere such as divx player, Premiere or even uploading it itself directly to YouTube it never has this issue but always does in Quicktime. I have noticed this one other time on another computer too. So I'm on Windows 7, and it's an mp4 file
