Hi Matt….
If each output is in it’s own sequence, you should be able to close Premiere, open adobe media encoder, and import the Premiere Project.
Once that is done you can select a sequence from the Project to output as WMV.
However, I’m not sure there is a way to tell media encoder to output all 72 individual sequences in one swoop. Likely have to submit one at a time.
There are capabilities to do something similar in AE, but it assumes you have a set of clips to start with.
