Let's users use a custom function to create the video.

​

The custom function must:
4
​
5
- have a 'scene' keyword argument to accept a Scene() instance
6
​
7
- have a 'videomaker' keyword argument to accept the CustomVideoMaker
8
    (self) instance
9
​
10
- have a 'video' keyword that takes the Video argument
11
​
12
- return the instance of Video
13
​
14
The custom function can manipulate actors and camera in the scene and
15
​
16
add frames to the video with 'video.addFrame()'.
17
​
18
Once all frames are ready it has to return the video object
19
​
20
so that the video can be closed and saved.

:param video_function: custom function used to generate the video's
