See, I don't quite understand this. MPEG-4 is the name of the codec.
There's MPEG-4 AVC and there's MPEG-4 ASP.  Are you saying I should
use "H.264." for MPEG-4 AVC and then use "MPEG-4" for MPEG-4 ASP?

Yes.  See the post where I stated this:
     "The sample commands that I  found online didn't work."

Yes.  That was the previous thread.  That's 3 weeks old.  Over the weekend I posted
the full ffmpeg command and the full output.  I know you saw it.  Because you answered
me. See the post titled 'ffvhuff -> rawvideo: all pixels have blue tint.'.
 
Thanks for trying to help me, Carl.  It seems we aren't on the same page 90 percent
of the time when we communicate.   Thanks for trying.
