I just purchased an Apple Power Mac G4 1250 minitower that I plan to use soley for video editing. I did have the Powerbook G4 laptop, but decided to get the desktop unit instead because I realized that I'd probably want to upgrade quite a few things on it down the line. When I bought it, I also decided to pick up the "Final Cut Express" editing software due to the fact that they had a discount on it. It usually sells for $299, but if you buy any macintosh, they woud sell it for $99. I was reading the literature that came with the software and one of the things it recommends is that you get an external hard drive to edit your video on, other wise you might have frame drop outs and other problems. I have already been hearing this from quite a few people, that I should use a seperate hard drive for this purpose. Is there some special reason for this? Is it because the main hard drive is busy running other applications and to have to render video too would be to complex to do it smoothly and with no frame drop outs? If anyone has any opinions on this, please share them. Thanks. Tunes Man.
