I've shot a video at 1080 30fps realized you really cannot slow it down because it gets very choppy. However I just shot one at 60fps, and slowing it down also resulted in a bit of choppiness (though not as much). I'm using iMovie and you can slow it down whatever % you want. My question is: When filming at 1080 60, is there a % (like 50%) or some multiple that you need to use to get it to play smoothly? Will some other % slow down not work as well due to frame rate? I really don't know much at all about frame rates and don't understand what the various ones do for you. I'm usually filming in Medium FOV. I know there is also 720 120, but I'd rather stick to 1080 I think. Hopefully this question makes sense. Any help is appreciated.
