I don't know what editing platform you are using, but I shoot regularly on a Panasonic HMC150, and you will have to account for slow-motion prior to shooting and in post-production. What I mean by that is anything you want in slow-motion will have to be shot in the 720p@60fps setting and then depending on whichever editing software you are using, you will have to crank that footage down in order to make it slow-motion.
For example, I use Final Cut Pro, so when I shoot something in 60fps, I have to make sure to change my capture settings to account for 60fps before I log and capture. Then once its captured I use cinema tools to conform it to my timeline frame rate which whill usually be lower (23.96fps/29.97fps etc)
