title: Python - Console closes after the code has been frozen
body: <p>I wrote an app in Python 2.7 that retrieves the length of media files using moviepy. If I run it from the command line, everything works fine; but after freezing the code, when I run it the console window closes immediately.  I've tried cx_freeze, pyinstaller and py2exe, all with the same results.  Is there something wrong with my code or is this an issue with moviepy?  I'm testing on Windows 10, this will be used on Windows 7 in the end.  Here's the code:</p>
