@KojiKnight:
I just tested and ffmpeg uses all of my 4 cores pretty equally on my i5 3570k, what CPU do you have? I read that by default ffmpeg should automatically allocate the optimal core-load depending on the codec used :/
In any case if you want to try a forced core usage replace the last line of my script with this:
If I read it right that should force it to use 4 cores.
EDIT: Okay it's a problem with ffmpeg itself, you can read more here

Multi-core support seems to be erratic at best :/
