I am importing HD footage from my camcorder. It has about 60GB of space, and I imported around 2 hours and 20 minutes of video. However, it takes 115GB of HDD space on my computer. How is it taking so much space, when it couldn't have possibly taken that much space on my camcorder? Then, what's the best way to export all this footage (I don't need to edit it, just wanted to cram together all the clips) into a reasonably sized file (one or two DVDs)?
