Grossing video

I have long thought that a video grossing manual would be a good idea but I never really had a good handle on how to implement it.  A good friend suggested a method and since then I have been thinking about it more and more.  I'm getting closer and closer to buying an HD video camera and beginning with the first chapter of the manual.  I'm sure that the first several versions of the first chapter will be hopelessly flawed but I will hopefully end up with an acceptable  and usable instructional guideline (I don't want to call it a 'manual' just yet).
