"""
This demo display the capabilities of Pymiere to batch some actions, without any human interactions.
It will start Premiere Pro, open a prproj file, pull data from it, make updates on it, save and close Premiere.
Before running this script make sure that you have a valid prproj path in the EXAMPLE_PRPROJ variable, the prproj should
contain at least sequence named 'hello world'. Also make sure no instance of Premiere Pro are running.
