The video tutorial explains the onMousePress and onMouseRelease functions, which capture mouse click and release events to create and modify circles on a canvas. The onMousePress function captures the x and y coordinates of a mouse click to draw a circle, while onMouseRelease changes the circle's color upon release. The tutorial also covers how mouse events differ from regular events, particularly in terms of inspecting elements using the control key.
