After a while of working on it, I've finally got my screen recorder to work in C#. I'm looking for suggestions to improve the video quality as well as clean up the code a bit. Specifically I want to create a method that resets everything after the screen recorder is finished, but I can't think of an efficient way to do that. Any help in these regards is appreciated!
