For mine (which were both film, or "digital video"), i chose editing and lighting, i wasn't allowed to just shoot one thing and use that for lighting and editing, i'm not sure if thats a rule my teacher made or a vcaa one.
for editing i shot some basic stuff just getting out of bed getting ready for school etc, for lighting i just did shots of different lighting effects, was very easy, some other people in my class did scriptwriting or story boarding etc.
basically it's just two aspects of what you may or may not do depending on your choice of medium, you also have to write a statement of intention, and a evaluation once you have finished, make sure you put a lot of effort into these, because they can sway your grade a lot. uuhh thats all i can think of at the moment, probably a bit to late at this point, hopefully it's helpful to someone.
