Can anyone recommend software for creating overlay animations for educational math videos like this one: https://youtu.be/cuaOfuiD2Ks
For those who can't watch the video:
I want to be able to overlay animated lines and images. In the video she draws the angle in the air and and the angle gets drawn on the screen. Same with the compass. The compass follows her hands as she marks (red lines) off on the blue lines.
