Thank you Woodstock. What you just told me answers my questions because I have an "older" computer with one core that is using almost 100% of the CPU and takes almost 8 hours to compress a video. Sounds like its time for an upgrade.

So is there a means to set how many cores of processor the program uses without using/writing your code? Does MakeMKV automatically use what's available on your processor?
