Hyperthreading-supported video converter

Hello, fellow TH peepz!

I was wondering if anyone knew of any video conversion softwares that actively supports HT technology, as I will be doing a lot of it soon.

I'm currently using Format Factory(for video joining), and Any Video Converter(for the actual format conversion) and they work... okay, but I heard I can get better and faster performance if I can fully utilize my 3770K's hyperthreading, and apparently both those softwares weren't programmed for the technology.

I don't mind paying as long as it can get the job done.  

I'm currently looking at this:

But honestly, I know nothing much about it.
