Choppy Footage - Can I Correct It?

What you are experiencing is a result of the 25fps Footage combined with your tilting speed.  

GeraldUndone did a video about this that did a good job of breaking down what is going on: https://www.youtube.com/watch?v=qAVfIQ2G7Io

Basically you are moving fast enough that each individual frame is happening spaced apart from the previous one, causing the image to jump from frame to frame.  If you were going faster it would blur thoroughly and would be less notciable, but you'd lose the visual interest of the detail present in the shot. 

I used to have this ALL THE TIME until I watch that video I linked and started going slower with my pans and tilts. Or whipping them when I wanted faster motion.  

Warp Stabilizer WON'T help in my experience.  Fast motion like this really screws up the analyzing of frames so you end up with either a very jumpy and jello-y warp stabilization or it crops in far too much trying to compensate.  

The best thing I've found for this is to switch your playback speed to "Optical Flow" and adjust your clip speed to something that makes it look a little better.  If you aren't familiar with that, Right Click on your clip -> Speed/Duration -> Time Interpolation and select "Optical Flow". The clip will need to be Preview Rendered to see the effect taking place, but once you do, tweak the speed of the clip (re-render), and see where it looks best.  This is my favorite use of Optical Flow speed.

RED also has an article on their website to break this down for you: https://www.red.com/red-101/camera-panning-speed

check out the warp stabilizer effect choosing smooth motion and playing around with the options.  Not sure if it'll help, but worth a shot.
