Okay - first just let me apologize if I sound like an idiot w/ these questions - I know just enough to be dangerous. Here we go ... I have 1 hr of HD video from an HD mini DV that I just downloaded into IMovie HD -- I was shocked to see it took up 46GB -- do I have a setting wrong somewhere? Next question: I went to use Popcorn to compress the video for Itunes and/or to burn to a DVD -- it cuts the video quality in half?? Bottom line: how do I keep the HD video quality and get it to a portable medium or Apple TV w/o taking up a ton of hard drive space? Thanks in advance for any guidance!!
