'jerkyness' has many reasons. one is photography (yepp, in Hollywood, the 'cameraman' is a Director of Photography):
we are used to notice motion-blurr - watch any action-movie frame-by-frame: not a single 'sharp' picture. esp. when action takes place in foreground, a shutter-speed of >1/100 makes the single frame crystal sharp as a photo, but the 'jump' of content in the next frame, we'll notice as jerkyness.
so, one option is, to lower the shutter-speed on your video-cam to add 'natural' motion blurr - this is often limited, I like to use socalled neutral-grey filters.
other option is diff. blending modes in post.
I made you a demo:

focus on the ball in foreground and the players in background:
recorded with my cheapo 40€ Kodak Z1, 720/60p (doesn't allow any manual settings, plastic lense etc)
edited in FCPX, in a 25p timeline
in 'normal speed/ everything nice 'n clear
in conformed speed, slowmo: 60fps played back with 25
in 25% speed (conformed is 42%), you'll notice a slight 'stutter' = shutter speed too high, action too close
in the ReTime/Video Quality Menu you'll find three modes: normal, blend, optical flow; next is
in 25%/blended, motion of players, esp. in background feels smooth; ball in foreground rotates too fast to allow a 'natural' blurr, differences btw frame#1 and #2 are too big for a nice blend
in 25%/Optical flow, motion of players, esp. in background feels even smoother, but ball still rotates too fast for a good result (getting very obvious in 10% speed, notice the 'ghost' around the ball)
summary:
best result is 'real' slowmo: high fps recording, low fps playback
add natural motion-blurr by low shutter-speed
if action is 'far away' plus camera is (mostly) static. optical flow results smooth motion.
if action is close-up, you should use a device which allows manual shutter speed control PLUS blending/Optical flow.
