How can I improve workflow throughput? In using iMovie and/or FCE, it seems there are some bottlenecks and restrictions. For example, in iMovie, if you're importing, you can't do anything else in iMovie. If exporting ("Sharing"), it seems my hardware is underutilized. I have a 2009 Nehalem 4core 2.93, standard drive, 8GB. I notice that when exporting/sharing (through QT Pro), Activity Monitor shows 4 cores working at 30% at best. A friend's new 6core/3.33/12GB with SSD shows similar behavior. My question: Are there any recommendations for hardware/software/techniques that can make things go faster? Upgrade to FCP? PCI cards? Sorenson Squeeze? Thanks!
