Hey, it's my first post around here so don't expect too much from me.
I'm trying to delete a little bit of an elipse to create two semicircles, somthing like this:





The thing is that my background is not white so i can't create a mask like that, i tried the eraser tool but didn't worked out.
You can see what i want to do here: http://i.imgur.com/NUw3zhk.png
PS: I'm a noob in after effects.

You can use animated(or still if you don't need animation) masks to delete the parts of the circle you need deleted.
