What do you use to edit?
How much slow-mo do you actually use in your videos?
For all the talk about fps, most video editing programs (like iMovie) don't even take advantage of the extra frames unless you know how to conform the files in advance. I personally stopped doing slow-mos in my edits, as I feel if it's not 1000fps Cineflex it looks cheesy. My 10 cents...
Not sure about iMovie but windows movie maker lets you slow down or speed up a clip really easily. If you slow it down to half (30fps) it dosnt look cheesy. It should look just as fluid as 60fps on most tvs or screens
