I think they need to be more smooth in order to look natural, so I would try with some basic easeInOut or easeOut instead of the jumpy movement and then go from there.
In my opinion interaction animations should be really fast, otherwise they slow down some users.
I also wonder if there is a timing issue with invoking the animations. Some of them get invoked immediately on hover and some of them seem to be delayed.
it's hard to tell whether the animations are functioning as designed for you, it's possible they're bugging out/skipping frames on your device. If you're able to email me a screencast (hi@kinopio.club, or post on the forums at club.kinopio.club) that'd be super useful for tweaking things
