Actually we've got it all figured out. We have x264 recipies that work great
 we are trying to bring them  over to ffmpeg because it's faster and a single
 pass no muxing packing and other wasted items. The problem is 
I can't get -bf to be honored at this point. 

It takes the parameter and silently does not thing 
with it. So that's the last remaining piece....

Has anyone gotten -bf or -bframes to work for h264 and ffmpeg?

All of this will likely wind up in the iSquint project if I can persued 
Tyler to use these settings... He's already set on ffmpeg.
