You dont really want to be using Permiere to be honest, its good for editing but Encoding is not something its designed for.

John you are asking what is pretty much impossible to answer.
Most post companies have a large rooster of programs for this type of work as it all depends on the source file "Master".
Even if your Master is WMV which is not good to begin with its comes down to the specifics of that WMV file....

Some programs are good for some wmv files and some for others etc etc
