Exactly as advertised

About time, finaly an app that doesn crash while rendering super fast. And this app doesnt deteriorate the HD into lower like other apps! This app keets the quality HD and works super fine on my 4s! I purchased happily after testing the free version for weeks. Me and my wife filmed our sons bday with two iphones in two different angles and reunited both videos into one with this great app thank you for this app!
