Hi Carl,

Agreed.  My end goal is to declare -b:v 2000k but due to the error I am
getting I kept removing switches to see if I could get a successful -pass 1
using current version from git.  So, you are able to get your command to
run with success using the most current version?

Any ideas why I am get the error that I do?
