As I've done a bit of video work, I knew you had to look at lighting, so I set up a full lighting kit. I was happy with the way I looked (well as happy as you could reasonably expect), but thanks to Facebook Live's bandwidth and the shiny TV screen, the text was difficult to view.
I'd managed to correct this and seemed to have improved the viewing experience.
There is specialist software, such as the brilliant and free OBS, which I have been using for other projects, but for this project, the feedback I've been receiving from parents and pupils is that simple is best. That's a lesson that many of us often forget.
