I have a video that I want to point out specific things in it while it's being played. Something like fading in a circle around a specific point of interest that I'm describing during a narration or maybe even just adding an arrow pointing at it, which ever is easier. I want to be able to have it fade in briefly and then fade back out again, or something to that effect. I would also need to be able to adjust the size of it for different objects throughout the video.
Can someone tell, or show, me how to do something like this. I am presently in the middle of editing a couple of short videos right now that I want to be able to do this in.
I am using SONY Movie Studio 13 Platinum Suite.
