Sorry for the false alarm, folks! Just a brain fart!

Truly sorry everyone, it honestly appears that I had a Total Public Spaz Out.

I could have sworn that window expander in the export settings GUI that did NOT bring me  bitrate selection options

But I went there again, and sho 'nuff

it was there...

So I think we can safely say that the shame is on me.

Thanks for all the help, sorry I squandered anyone's time on this.
