So in my online courses I field questions periodically about what my studio setup is like. (You might be surprised at how much low tech you can get away with!) The good news, of course, is that you don’t have to spend thousands to produce your online video/screencast courses.
In a nutshell, my setup isn’t too far removed from those Gideon has setup (third video below). But, with a few minor tweaks (see the first 2 videos) I’m confident that you could easily produce at even higher quality video/screencasts than those you’ll see in my coursework. So, please don’t use me as your baseline, check out the shoe-string budget creativity that some of our colleagues have put together… then do it!
