a problem about the CPU usage by my PR CS5

Dec 8, 2012 5:25 PM

I get confused that when I use my PR CS5 to render an 1920X1080 mp4 format file,the cpu usage was only 36% at most ,PR CS5 64 bit ,can't be........., So I think  it could be up to 90% or almost 100%,becourse when I render a 720 X 576 mpeg format file it alwayz can be 100%,Do I set something wrong in PR CS5 or just my computer can‘t afford the HD film rendering?Here are some pics of computer and my problem screen shot.

    The CPU will use whatever it can in terms of load, unless it is waiting for other components to finish their part of the processing first. It is like walking along the beach with your dog. The dog has to wait for you. Now imagine your grandparents accompany you. Now you have to wait for your grandparents. Same with your computer, the CPU is waiting for other components.

    Try the PPBM5 Benchmark and maybe we can find the weaknesses in your system.

    without adding any effects the cpu is 100%usage


    That would indicate your export is using an effect which runs on the GPU and slows things down.  Magic Bullet is one example of such an effect.
