*Phew* Had to think of a title to meet the new posting rules.
Thanks to mtlynch at Reddit/Datahoarder for the link and tutorial.
I won't speak to his capture technique and hardware, but his implementation, additional script and use of it sounds like it may be something many users have asked for. Automation of scene changes and way to quickly utilize the info for editing.

This all goes over my head, especially since I haven't done any capture or editing in years, but it sounds interesting and hopefully helpful!
