What is you purpose in writing this?

If you intend to make a generic erudite glossary for all video terms,
then the mailing-list for using FFmpeg is not the place to do it.

If you intend to make a glossary useful for FFmpeg users, then get rid
of all the useless lint about obsolescent standards (H.262? seriously?)
and irrelevant terms. In particular:

> PAR (picture aspect ratio [1]) [noun]: 1, The horizontal-to-vertical
>   size [3] ratio (H:V, e.g. 5:4, 3:2) for pictures. PAR is

get rid of this one altogether, because nothing in FFmpeg use it, and
rightly, because nobody should use it.
