It's not that hard to do in PTE, IF you don't keep forgetting how do do things. Lin would make this in about 10 minutes. Took me longer because I kept forgetting how to arrange "layers" to get the right things on top. I merged some of the action's layers to get the flap, front of the envelope (and inside) and the back. Saved these as pngs to preserve transparency. The only tricky part was that I had to rearrange the layer order in a couple of places as the video proceeded so that the flap was on top of the back of the envelope but when opened, the photos were on top of it. After that it was rather smooth sailing. The nice thing is that once a show is done, you can save styles so that it can be reproduced with different elements (photos) without having to redo everything. Just load the images and click on the style.
