Before you ride off into the sunset together, I’d love to learn from your organization of those keywords you mentioned. As a taxonomist and librarian I understand how useful and essential this is and yet also how difficult to maintain. Did you employ a standardized industry-wide system? Something particular to your own style that only you would understand? Something you could share for reference?
Regardless, your work has set the gold standard for everyone creating video on the intertubes, and as someone with no experience in film I’m personally deeply grateful for all I’ve learned from you both. Wishing you happiness and joy in all your future creative challenges! Bon Voyage.
