After I've researched a lot on google and youtube, all of the information I found on removing the black background for me was either irrelevant or useless. I created an animation, a basic set of circles and rectangles that come up. When I click the 'transparent' button and render it as mp4, it comes out with the black background.
Render it out with an alpha channel and a codec that supports alpha, like Quicktime Animation or Quicktime_DNxHD.
