'top' cpu usage

Server Config
1

I am using top to determine how much cpu I am using. I am encoding videos, yet each core seems to be about 20% used, where I wish it would use more. Maybe I’m just reading this wrong. Attached is a screenshot.

If I’m not using my full cpu capabilities, then please let me know how to with ffmpeg.

looking at the top report it seems you are using average 70% o rmore of each CPU.
What gave you the 20% figure? you have to see top report as split into various portions like system, user space etc. ie. you need to total the row for CpuXX
