It takes us quite a while. Planning, art & diagrams, triple checking that everything is right and that we are not lying to you, and of course recording (sometimes 10 times before we get the video the way we want it to be). Not to mention thumbnails. However, we love making these videos for you guys, and only want to publish our best efforts. So to give you a vague number since it varies depending on what video, I would say a total of 10 hours of work goes into each video.
