For me, my basic keywords are related to my folder organization for each job. On my external edit SSD, I start with a job folder that contains subfolders: Day 1 original footage, Day 2 original footage, etc., stock footage, VO, music, SFX, etc.
After I create my Library, I import all those folders at once into the event created with the Library, which creates keyframes based on the folder names. I may create more Events in the Library if I want ones for different episodes, or whatever.
From there, if needed, I can add folders in the browser to contain groups of keywords. And as I review all my assets, I will create more keywords (CMD-K) to make it easier to find things. It’s not a one-click process, but it keeps me organized.
