I have been looking for months, on and off. Is there any place that shows how 
to form a working ffmpeg command line? I'm trying to figure out how to use a 
fieldmatch filter.

It’s a good idea to show us what you tried and what went wrong so we can 
understand your problem.

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.
