I understand about the need of the file. Sorry, I can't provide it. I'm not
looking for absolute answers; if I were, I would have one of you sign a NDA
and hire you to write the correct command line(s). What I hope for is a
general idea as to how something might be done or why it might have failed.
i.e. I have read many references to the supposed necessity to compile ffmpeg
with certain flags enabled in order to use the ProRes codec. I have also
read where this isn't necessary anymore. Seems awfully fast for a codec I
could swear ffmpeg only recently started including in the stable
releases(?). So when I posted the output and the sample command lines I used
I expected someone to spot a glaring mistake. Didn't happen.

Such is life. As far as not being playable here or there. Not my concern
here as the ONLY place this file will be played is from a web page and that
through an older version of Floatbox. It plays it happily. I know, I know,
"You have a way of making the file you want why don't you just use that and
be done with it?" Because, it is done from my PC with a 3rd party piece of
software called SUPER (c) which is in the same genre as Handbrake, etc. and
I need my server side ffmpeg to do this. 

Not faint of heart here, I started myself in web development 10 years ago. I
am completely self-taught and because of the nature of this beast, still
learning. If I need to get down to the source code and figure it out, I
will. 

Can you provide a sample command line that would do what you are thinking
concerning the mov IDs?

Next, what is the best way to view the errors? Is the error I see in the
output, is that it?

I asked this before, please recommend some reading material/books that I can
use to learn about ffmpeg.
