From the football ( the game you play with your feet, not carrying the ball in your hands) corner, a simple effect: The Magnifier

Install it in your Effects collection.
Drop it on a clip to magnify a scene.
Three controls: Size, X-axis, Y-axis.

Sorry, no OSC, 'cause you can not keyframe them (I was told …).
The tricky part: the snippet in the glass has to move to opposite directions, otherwise, you can not magnify the whole frame... When you open it in Motion, you see what I mean.  

New Features
