I've used FFMPEGX for years for all my conversion needs - not perfect, fairly complex, but works great when it works. Recently been looking for a more 'general-purpose' converter/processor; tried some things, but - meh.

Downloaded Handbrake yesterday, and WOW! FAST, CPU-friendly, smartly-designed, works seamlessly, lots of smart user-friendly touches. Works on anything.

A joy to use - applause to the crew! Well-done, gentlebeings!
