+1 I second this. I have in in my Z7 HDV, it does 3-6 and 12 seconds at 120 fps and uses memory. Once the slowmo has been recorded it writes it down. It also has a cool feature where you press record after the event has passed, meaning that i.e., if a golfer swings the club press it after the swing, then it writes down the previous 3 seconds. Very useful for animal docs.
