Here is what you wrote:
"The following makes little sense, it is just meant as an example:
$ ffmpeg -f lavfi -i testsrc2,field -vf bwdif -f null -"

That "explains" nothing. Worse, it seems crass and sarcastic. The perfect word is "snarky". Do you 
know that word? It's a word invented by the man who wrote "Alice In Wonderland". Sometimes it seems 
that what you write is meant to pull people down a psychedelic rabbit hole and into a fantasy world.

Just because something is possible with ffmpeg, if it doesn't make sense to do it, don't mention it. 
If you do mention it and you write that it makes "little sense", then explain why it makes little sense.

In this case, it doesn't make "little sense". It makes *no* sense.
