Hide all warnings in IPython

I need to produce a screencast of an IPython session, and to avoid confusing viewers, I want to disable all warnings emitted by warnings.warn calls from different packages. Is there a way to configure the ipythonrc file to automatically disable all such warnings?
Place: import warnings warnings.filterwarnings('ignore') inside ~/.ipython/profile_default/startup/disable-warnings.py. Quite often it is useful to see a warning once. This can be set by: warnings.filterwarnings(action='once')
