editor.py

"""
This file is meant to make it easy to load the main features of
MoviePy by simply typing:

>>> from moviepy.editor import *

In particular it will load many effects from the video.fx and audio.fx
folders and turn them into VideoClip methods, so that instead of
>>> clip.fx( vfx.resize, 2 ) # or equivalently vfx.resize(clip, 2)
we can write
>>> clip.resize(2)

It also starts a PyGame session (if PyGame is installed) and enables
clip.preview().
"""

# Note that these imports could have been performed in the __init__.py
# file, but this would make the loading of moviepy slower.
