Our EDIUS tutorial contains a great deal of information and is split into several sections. You can buy certain sections of the tutorial on their own. You will get the whole tutorial interface with links to all the various chapters but you will only get the video clips for the section you have bought.
You can buy more sections at a later date and when installed they will be added to the sections you have already purchased. It is cheap to buy the entire tutorial at once, but if you just want to see certain sections you can now do so.
