While the program does a good job of keying out the green, I find that unless your format and size between the layer are the same this is something of a pain. Perhaps I'm simply not familiar enough with the program to understand. I can't simply drag the size so my subject on the green screen fits properly into prespective on the background scene. It also seems very difficult to position it. What am I doing wrong? I cannot seem to figure out how to do simple manipulatio of the size and placement of the different layers. If I simply use the drop down to change the size, both pictures change instead of the one. Otherwise the effect of keying out the green works very good.
