Joyoshare Screen Recorder helps me record screen in high quality without time limitation. I often use it to make video tutorials for my art students. But it seems that it cannot support a webcam or I just didn't figure out the right way. I think it would be better if I can record myself speaking while showing my students what I am doing on the desktop. So does anyone know which tool I can use to achieve that? It better be free or low price, and beginner-friendly, as I am not tech-savvy. Thanks in advance.
