I made this video on Windows. It uses a video backdrop, a two layer fake suitcase png, and some socks and hats in front of a really bad green screen. I must say, that chroma key works swell.

To make the backwards version, i made a new project, added a time reverse mixer, and imported the finished forwards version as a child of the time reverse mixer. This mixer can be found in the sub-mixers folder.
