Sounds good. I'd agree that editing is key, and best to edit into short digestible chunks.
IMO Most common editing fault is an over long intro' and too much dead time.
Watch a few vids from other people and pick out the mistakes.
One problem is that the subtleties we are used to looking at are hard to see or film.
No set tillering would be a great topic... I'd think the mass thing could get heavy... (I've never got into it).
Whether you do it as short individual vids or a sort of chapters, depends on how it will be published... Youtube? DVD?
Gotta remember that most people have a short atten.... oooh look a squirrel....
