Thanks the examples,

Gary yes I am aware that the objects should be named to make possibly the tweening, but in my example just wanted to register on the frames how to do a button. For example tutorials could be done similiarly, attaching beside in text maybe that which layer why came above. Sorry if it was confusing, it is really not a traditional animation. Rather just frames after each other and putting an additional layer in each.

Briefly so your technique to improve the .avi quality is making a bitmap copy for those elements, which are anyway not supported in flash. And seeing Egg's example considering the size optimizing too, however in .avi that is not a big factor, but definitely if someone would like to use it as .swf on web pages.

Thanks just again your efforts to explain
