The method I’ll show in the tutorial is simpler yes.
I will show how to draw an animated route on a map, but the method can be used for a lot of things, including making an animated box border.
You just draw a rectangle, and animate it by adding a Trim Path layer.
The background from Shotcut is visible in Glaxnimate so you can draw directly over the object of your choice, and the rectangle angles are always square.
