post fix for pan stuttering?

Is there any post fix for image stuttering on pans shot in 23.98 1/48 sec on a Sony FX9 in UHD? Obviously go slower next time but its too late for that. Does that issue improve with broadcast or on regular video monitor as opposed to a computer monitor?
I'm guessing in the future 29.97 would be better . Would i want a slower a shutter speed? also for motion blur? there used to be a rule of thumb in film not to pan across any object faster than 7 seconds across the frame , but film was a more forgiving situation because the projector shutter opened & closed twice with each frame.
