While I was searching for a multi-screen video player/synch system for my major, I came across Frame Substractor by the same developer (http://www.zachpoff.com/software/frame-subtractor/) This thing is brilliant. I really like the effect it makes... it seems to almost create water-colour paintings of my day-time driving footage. I like a lot. Gotta think of something good to use it for though. Hmm...
On a side note, I used it on some steps I shot earlier and my feed were essentially erased... I'm thinking the same thing could be achieved if I were to shoot footage of Northbourne of of Garema... More food for thought.
