You could have just omitted the irrelevant lines. And no, that does not
mean omitting everything, but most of these:

The first ones at the beginning, and the ones at the very end are
relevant. (And differing lines, i.e. warnings and errors.)

Anyway, enough of that. This is relevant:

This shows that the audio sample rate is indeed converted to 44.1k,
unlike what you claimed in your original mail.

The final video bit rate is very close to what you specified. If you
need more precision, you probably need to choose 2-pass encoding.
