Thanks, Carl.  Much appreciated.

Out of curiosity, is there ever a need for a second filter_complex? Is
there anything that ffmpeg can do that you cannot put into a
filter_complex so that you then have to have a second one after the
non-filter-complex statement?  (and where you can actually grab the
output of same in the second -fc)

Will do.  Looking at it it has a couple of annoying indirections that
you don't notice after a while but that make bad mailing list content.

I was using git from yesterday.  Working spendidly, BTW.  Very happy
and it was a fun fight for the screenshots.
