Green Screen Fun - "Magnifying to see what's underneath" OBT

I love using green screen. I made a cardboard magnifying glass with a green piece a paper as the lens. Using the magnifying glass, I used iMovie on the iPad and Mac to create a final product. Green screen or Chromakeying is a little counterintuitive, you need to place the background on your time line first and then add the chromakey layer second. When using the Mac version of iMovie, after add the chromakey layer on top of the background, the Green screen/Blue Screen effect needs to activated. In the iPad version of iMovie, the background layer needs to be added first, however, when the green screen layer is added, "Add as Green Screen/Blue Screen" must be added while adding the clip. I also used Final Cut Pro to put together a little how to movie with a final product at the end of the movie. I plan to include this into my OBT project. I added three files below so that you can try to do it yourself. Have fun!

Recording the Process of making the videos. I used Final Cut to edit the video version at end of the video. I always prefer Final Cut Pro because I have more control when making videos.
