Previously I was using a macbook air to render some image sequences into 1080i video (timelapse). QTP7 would max out the 1.8 i7 until the process was complete. I recently upgraded to a mac pro with a 3.46 hex xeon and 16 gb ram. While rendering the exact image sequence I did on the air, the pro is only using 7.84% of the processor and the speed does not seem much improved?? Is the data transfer rate my bottleneck now? Thanks.
