Here’s a few topics that might interest you and you could certainly follow up if you had some additional questions, I’m sure someone would be glad to expand on specifics that weren’t already covered. I seem to remember that at least the first of these has some pretty good information in it.
Since I don’t do video recordings this is probably the best that I can do to help but hopefully at least the first link is somewhat informative, I think there a few more topics in the search results if you want to dig a little more but I didn’t really have time to further refine the criteria.
