I had a bit of a "duh!" moment yesterday.
I keep trying to make a big video with a lot of parts to physically be done and recorded, and THEN edited together.
Then it hit me like a salmon, swimming upstream to spawn and smacking me in the face with its tail - I should just break it up so there's shorter videos and upload those, and then release a combined version so people can watch the whole thing.
So I'm gonna do the talking head and ADR for the first battlemat and get that out. Terrain to follow. I may eventually get to the point in production and speed that I don't need to break it up, but for this one, I'm gonna.
