In tutorials particular parts of the screen are marked with self-completing circles, squares, etc. how do you make these animated shapes? I use Camtasia studio 8.4.2. and the extract is from the tutorial:Audio Series: Working with Music
It looks like a few people have already pointed you in the right direction :). The shapes you saw in the Working with Music tutorial are indeed callouts. The only other thing I'd add is that the self-completing ones are specifically sketch motion callouts: http://www.screencast.com/t/vktqcPsK.
