In this video I take advantage of the three layer feature in the Green Screen app. I am able to layer text, tellgamis, and live video clips to illustrate the endless possibilities of this app. Great for different content levels as well as different ages and stages of learners. Best APP to to drive creativity in the classroom that I have seen in a awhile. Will get learners to the upper ladder of the SAMR model.
Take a look at Veescope Live for iOS. It has much better green screen capabilities. https://itunes.apple.com/us/app/veescope-live/id568390801?mt=8&ign-mpt=uo%3D4
