Dont buy this app if you have the expectation of using this to even replace a green screen. The only way to add a second layer is if you are patient enough to erase the top background carefully. This apps studio does little to assist and has a basic concept. I had a higher expectation for this app so I got a refund. Definitely not worth the buy. The entire pitch this app throws is different when you encounter the unprofessional interface utilized into the app.
