[FFmpeg-user] ProRes to x264

[HallMarc Websites]

Don't want an .mov or .avi or anything but .mp4 
It doesn't play in Quicktime as expected and as I described when I posed the
question.
I realize that ProRes codec is still new to ffmpeg. What I am looking for is
a general answer along the lines of "You need to -enable-version-2" or you
need to include these flags in the command line. That kind of answer.
