I use Handbrake for all of my movies at home. And am amazed at the quality. I find 4mbps stream to look better from Handbrake than a 10mbps stream from AME. I've been considering using Handbrake more at work. But I'll probably test that out first to see the difference going to ProRes then H264. When with AME, I skip the ProRes step and go straight to H264 from PPro.
