While 60i isnt technically a faster frame rate, you can create more frames because there are twice as many "interlaced frames" (obviously), which produces a better effect than simply slowing down 24p or 30p People bash 60i but for slomo it really does the trick.... Unless you have an HVX which can record 60p, but i doubt most of the punks on this forum have the cash or nice enough parents for an HVX.
