If you are on Windows, give MediaCoder (
http://mediacoder.sourceforge.net/index.htm ) a shot. It has a pretty
clean interface, and has product specific to the iphone that gives great
results. It's based largely on mencoder, ffmpeg, x264, mp4box, etc but
wraps it all up in a pretty good gui. If you are on Mac, I would
generally suggest VisualHub (http://www.techspansion.com/ ), but as that
product has been discontinued, and it's replacement (
http://sourceforge.net/projects/transcoderredux/ ) seems to be still in
the early stages, I'm going to suggest that it might be easier for you
to run MediaCoder in Parallels or VMWare Fusion. VisualHub might be
found in some of the more disreputable places on the net. There's also
ffmpegx ( http://www.ffmpegx.com/ ) but I don't like it as much as
