You will also need a recent version of the software ffmpeg , preferably downloaded directly from the ffmpeg website.
First method : if you have pip installed, just type this in a terminal (sudo is optional on some systems)
(sudo) pip install moviepy
(sudo) python setup.py install
PyGame is needed for video and sound previews (useless if you intend to work with MoviePy on a server but really essential for advanced video editing).
ImageMagick is needed for all text generation, GIF import/export, and much more .
For advanced image processing you will need one or several of these packages. for instance clip.resize requires that at least one of Scipy, PIL, Pillow or OpenCV are installed.
If you are on linux, these softwares will surely be in your repos.
OpenCV is very optional, its installation is not always simple and I found it to be unstable, be warned ! The installation seems easy for Windows. On linux, here is what I found on the Internet:
Remove any other version of OpenCV if you installed it through a package manager.
Unzip the source code of OpenCV 2.4.6 in some folder. open a terminal in this folder.
Make a new directory and go into this directory:
mkdir release cd release
Run cmake. Here is the line I used:
cmake -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=OFF -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON ..
Run make. This may take a few minutes (15 minutes on my computer).
sudo make install
And voilà !
You can check if it worked by opeing a Python console and typing
import cv2 print cv2.__version__
Advice: do not throw your release folder away. If later you have strange bugs with OpenCV involving .so files, just redo the sudo make install step.
