Tedious and Inefficient
Trace bitmap: "I could tell them but they still won't understand it" ?
Maybe if you learned to make better tutorials they would.
This was very laborious and frustrating to sit through - the animated illustration of every step was totally unnecessary. And most people know how to open a new file in flash. Other than that, your method on manipulating sprite sheets isn't very efficient - there are plenty of little things you could have done to speed up the process.
The point of a tutorial is to be brief, concise and to illustrate the steps involved precisely. The useful parts of this tutorial were completely lost in the pointless animations and obvious steps.
