I am trying to spec a system for grading selects and exporting with Red Alert. I will be using a dual quad core 2.66 Mac Pro, and only working with 2k material [for now], exporting it in Avid DNXHD 185X codec. I have heard that real-time playback of rushes in RA can be a problem, at least with 4K files. So would there be any benefit in choosing [smaller] 10,000 rpm drives instead of [larger] 7200 ones?
Would this enable real-time playback of 2K? Or would I get that anyway with cheaper drives?
Thanks for any advice.
