title: moviepy not finding ImageMagick on win
body: <p>On a Anaconda3 4.1.1 distribution on Windows 7 64bit I installed moviepy 0.2.2.11 by using <code>pip install moviepy</code>. Now I want to test some examples with animated text which demands ImageMagick. So I downloaded and installed <code>ImageMagick-7.0.3-4-Q16-x64-dll.exe</code> but according to <a href="https://zulko.github.io/moviepy/install.html" rel="nofollow">https://zulko.github.io/moviepy/install.html</a> on windows the path needs to be specified manually. If I understand correctly this has to be done before compilation. However as I used pip for installation I don't know how to tell moviepy the path.</p>
  
  <p>Secondly it seems that there is no convert.exe. I can however use e.g. <code>magick convert image.png image.gif</code>. So is this version of ImageMagick compatible with moviepy at all?</p>
