Art, thanks for sharing your process/productions with us.
I don't do any video work myself at present, but I was wondering about this very topic recently. IMO, it is especially suited for motion imagery that doesn't involve actual MOVING contents/subjects (like the pool shots @ 2:30 & 2:47, the water looked a bit funky/jittery compared to everything else).
Other than that, I can only see this being a very nice way to future-proof one's shots happening today for future branding/usage purposes past the currently allotted timeframe the client pays for. Due to frame rate limitations, it isn't for everything, but it's getting close. Just a few more years and we might start seeing global/sensor-based shutters which could allow high-speed, hi-megapixel capture for ultra-hi-def motion use. Fingers crossed!
cheers,
Dan
