I know you want that, Carl. I haven't gotten that far. I need to know 
how to form a proper command line before I can take the next step.

What I have managed to do, such as using ffprobe to dump metadata, 
started from commands that I saw here or found on the net and that I 
hacked from there by trial-&-error. That was several months ago. Now 
that I want to actually process video, I need to find a way to construct 
commands. The documentation, for fieldmatch for example, doesn't show 
that. I go to the top of the 'filters' page and the documentation dives 
into a presentation of filter graphs. That doesn't do me any good if I 
don't know how to form a command line. Also, if I don't know what 
'[x:y]' is and what the components are, pages of presentation and 
philosophy doesn't do me any good.
