Switching to Zencoder was the best decision my company made to handle video uploads. They seriously are the best, by far. They even support full HD and audio only, and there are just a few file formats they don't yet support (like GoToMeeting). If you need video encoding, use Zencoder. Don't even try to figure out your own ffmpeg or related solution, it's not worth the effort.
