I went to Walmart and spent $15.15 on 14 sheets of fluorescent green poster boards and fluorescent green duck tape. This small investment just upped my game. I can now do really cool green screen videos like the big boys for literally a small fraction of the cost. Ha-Ha is all I got to say. Don't get suckered in by some video marketing self-proclaimed guru saying you need their training to do green screen. If you have a Mac like I do, you need nothing more than iMovie to edit the videos.
