I want to put video clips that are mpg and avi format that are around 700MB each. I was wondering after I reformated my computer and reinstalled this program it now takes over 8GB of space. It use to take under 4GB of space. What is the deal, I have all the options set as before, including the worst quality (super long play)but it is still takes up that much space. What could be the problem? I don't know why it has to take up about 4 times as much space to put on a 3 video clips that are around 2.1 GB of space.
