2K Full Res DPXs 75:1???

[Tim Fassnacht]

Hi All,

This just doesn't seem right. I'm rendering a 15 second clip on a Dual3.2GHz Quad MacPro (8-core). I'm getting about .32fps render when rendering out Full Res debayer to 2048x1152scaled DPX Frames. Crazy! I've reinstalled RedAlert a few times and repaired disk permissions- no help, same results. Source and Target directories are both on my a Sonnet SAS RAID (this thing blazes normally). Even stranger, it seems to dynamically shift CPU usage between cores, not utilizing them all at once. See grabs.

Anyone have similar results? Is this legit or does this seem crazy?

Thanks in advance:help:

to use all cores of the macpro, you must at least calculate 6 files at the same time with redrushes, speed when totaled will be 6 times faster than when you calculated them one at the time

Filip is correct the only way to get any kind of performance boost out of red rushes is to submit more then one clip at a time.
