Limiting the processor power for encoding h.264

Limiting the processor consumption for x264

Hi all,
I am new to encoding using x264. Of course, anyone knows that encoding eats a lot of your CPU power which might limit you from running other applications when encoding a video. Is there any way to limit the cpu usage for x264? I mean can I force x264 to use only 80% of my processor power.

The OS distributes CPU time dynamically. Lower the process priority of x264.exe to "below normal" or even "idle" and it won't steal any CPU time from other processes, but still no CPU time is wasted unused. There's no need to statically limit the CPU usage of x264. You could even limit x264 to a specific CPU core on a multi-core system, but there's usually no need to do that...

from the command line just use:
start "" /LOW x264.exe (then all the settings)
