detailed answer, so I can't get to all of them.
The short answer to the first is... you can't protect your ideas. Not
fully. You can't copyright an idea. So the more fully developed they
are when you present them, the more it's clear that you've done the
work and someone would be foolish to try to do it themselves when
you're imminently going into production, well... hopefully, that does
As far as format for pitching, TDF at Hot Docs, IDFA and a number of
other places have formal pitching sessions for international docs
during the year and they all have a similar format. You can read up
on it at the TDF website: http://www.hotdocs.ca/tdf_intro.cfm.
The only trade secret on securing pre-sales is to shoot a lot of
great footage and make it into a fantastic sample tape. And, if you
can, allign yourself with producers who have international experience
and contacts (all but necessary in int'l co-pros and presales).
Lots of luck.
