I use FCP 7, os 10.6.5 and shoot with a canon T2i. I copy the files over and convert them. On my home MP I have tonnes of space and juice, so I convert to Proress422HQ right off the bat. But for my MBP 2.0ghz, 4gig RAM, dual Hard drive set up, I think that AIC might be easier on the CPU cycles when rendering in FC. Do you think this true? Should I convert to AIC instead of Proress422 HQ for my laptop? p.s- yes, dual hard drive, that optical drive was useless.
