Here is what I want to do: I want to create an animated graph and store it as a video file, mp4 say. This file will then be used as an overlay on another video.
Using this example: http://matplotlib.org/examples/animation/moviewriter.html and this tutorial: https://www.youtube.com/watch?v=h0F5X4b7jug I have covered a lot of ground. What I have failed to achieve is a graph with a transparent background. None of the leads I have found searching the Internet have helped me. (I may have found the needed information without realising it...) Any help is appreciated. Another thing I would like to do is to present numerical data in the video or as a separate video -- think LCD display reading out numbers up-dated every second. Once again preferably on a transparent background. Here I have covered no ground :-( TIA, /Martin -- https://mail.python.org/mailman/listinfo/python-list
