You appear to continually avoid "what is it you wish to do with a

That's a fair observation. You deserve a serious response. May I
provide perspective?
It appears to me that ffmpeg commands have the following structure:
ffmpeg A [[B ...] -i C [D ...]...] [[E ...] [F ...]...]
[[i ]...] : inputs
A : general options
[B ...] : input-specific pre-options
C : input URL
[D ...] : input-specific post-options
...[[]...] : outputs
[E ...] : output-specific filters
[F ...] : output URL
Full disclosure: I don't know if all of the above is correct.
As far as I know, there are no input-specific post-options.
Thank you, Michael. I'll keep that in mind.
All input
specific options must be written before the input. Remove D.
General options can also be written before the output (between E and F).
Thank you! That's really good to know.
Filters are always output specific. So E ist just the filter chain.
True. I intended to indicate that E is an individual filter. I'm unsure
whether, in a filter chain, all filters are delimited by semi-colons. If
they are, then I can indicate it, thusly:
[[E [;F ...] [G ...]...]
E : filter
;F : following filter
G : output URL
