The point I'm trying to make is that running two pass encoding for that
specific bitrate is a terrible sub-optimization made for reasons that
very likely have no relevance to your use case. Multi-pass encoding
only exists to allow you to set the quantizer to hit a specific target
file size. Accurate target file sizes only have worth if you're trying
to store on a medium with limited space. If you're actually archiving
this stuff to DVD afterwards, then the cost to do so, time spent burning
and recovering from optical media, and expected lifetime, is a whole
other discussion.
