imovie is really aweful when it comes to outputting, been using FCP for 4/5 years, all the way since version 1. Its been an evolution since. Pretty cool stuff. iMovie is made for purely DV production. Where as FCP is more geared towards a variety of formats, hence thats what make FCP a pain to setup. But once everything is set its fine. can't teach FCP but can give you a few pointers to p ut you on your feet.
Anyway about network rendering. Still can't find anything about. I was pondering about it the other day but dont have much time to play around 🙁 Was gonna hook up my PB for a bit of extra boost and also plan to get another machine later, hoping for a 2nd Dual G5.
But according to Apple's Key note about FCP4 its possible. Unfortunately I'm still on Verison 3. like I said been quite busy and havent had the chance to upgrade just yet. The funny thing is that in version3 manual, not to use FCP with the network on..
So....
anyway guys have fun with FCP, pain in the butt, but once you get into it, its the best thing
