Hi, I would like to know which Mac Pro would be more beneficial - the 6 core (base) or 8 core (base) - I will upgrade the RAM later. I will use the Mac Pro for Final Cut Studio 3, Photoshop and iMovie. My workflow for video is as follows: 1) Dump data from my Sony NX5U (AVCHD format) onto an external hd (make backup dmg file). 2) Use log & transfer to change clips into ProRes. 3) Transfer ProRes clips into iMovie events folder using finder (workaround to using ProRes in iMovie). 4) Assemble clips as needed in iMovie. 5) Output XML to Final Cut. 6) Color grade in Final Cut Studio. 7) Output to BluRay using Roxio Titanium. Right now, I'm using 2008? iMac 24" 2.6? gHz w/ 4gb RAM. I use USB 2.0 external hd's. It takes forever for changing clips into ProRes. I use one external to house the dmg file and when using log & transfer I output the ProRes to another - still takes forever. What can I do to speed up process now? What about when I buy the MacPro? Everyone talks about RAID 0 or 1 but I don't really understand how it works. Sorry for what are probably lame questions to a majority of you - your help is greatly appreciated.
