Transcodes – I capture quite a bit of work in HDV. First thing I do is drop it on the G5 and let compressor transcode it all to ProRes 422, sometime LT. MacPro can edit or accomplish other tasks while this takes place. Also, I tend to transcode many final pieces on the G5 to MPEG-2 for DVD or H.264 for web. (Not as often for the web because the MacPro is SO significantly faster.) It all comes down to load balancing. The more time pressing or bigger budget projects utilize the MacPro more while the G5 preps stuff for the smaller budget stuff.
Background rendering – This is my own made-up term in the way I use it. You can send sequences to Compressor in the background now, but you still can’t render without tying up FCP. So for long form stuff with lots of renders, I’ll open on the G5 and let it do that, while I work on something else on MacPro.
The MacPro is amazing! But it still can get bogged down with HDD I/O, swap I/O, RAM and CPU jockeying. I could probably spend a couple thousand dollars to upgrade some more RAM and faster drive arrays, but its much cheaper and easier to utilize the old hardware. (I think that I get more performance from the G5 than I would from the upgrades too.)
