Alright im not a "newb" at premiere by any means. Im sure youve all seen at least one my little music video things. Well last night i was finalizing my next one called "The Deep Samurai". I had clips from 2 different sources and everything went fine. I edited them then I merged them onto one track. And everything was fine. Then when I exported I was shocked! It was as if everything from my second source was completely gone! When something from that source was on screen it was just black. It doesnt make any sense please help somebody!
