Wow. I started to answer this post and before I finished, a baker's dozen knowledgable guys are way ahead of me. You folks are something else with your collective pool of knowledge. Great group!
well i guess the other way to do slow mo, and not cost as much, would be to implement Twixtor in to your footage, i'd actually LOVE to see some hd100 footage mixed up with twixtor, i bet it would look totally amazing!
still capture via the components, get the fabulous colour range and morph it w/ twix
