> What exactly is the 'q=' referencing in the logging output? I know this is quality, but I'm not finding any useful info on the web to put any kind of key or legend to this value.

I think it's this:

‘-q[:stream_specifier] q (output,per-stream)’
 ‘-qscale[:stream_specifier] q (output,per-stream)’

Use fixed quality scale (VBR). The meaning of q is codec-dependent.
