Nice job! I always wondered about these fast-cutting music videos. How much of it is story-boarded/pre-planned and how much is just getting as much coverage as you can and figuring it out in the editing room?
For me at least, it's a combination of both. I plan as much as I can, but I don't give myself any restraints once I'm cutting it: if something feels right, I forget the planning and go for it. With this video, I had planned a rough outline and logged all the footage I was going to use, but most of the final edits were decided once I was actually cutting it.
