Im a hobby video editor that uses Sony Vegas via boot camp (Cant wait to try the new final Cut though) to edit 13.5 CBR avchd and h.264 video files. Last night I kicked up the rendering of a 9 minute video with some Color Correction and the Video took about 1 hour and 30 mins. that seems way too long for this powerful of a computer??? The Specs of the Imac are stock. Should I purchase more ram? Any other Suggestions?
