In my case once it was nothing to do with the drone / camera but instead the video settings on my monitor (refresh rate/frequency?) causing an appearance of stutter.
Having done plenty of testing i now shoot all video in 60fps i find panning much smoother at 60fps.
As the guy says below its down to personal taste at the end of the day.
Greetings all. There are a lot of videos on how to reduce stutter while panning, even slowly. I have not noticed any of this problem with the fast paced and turn with fpv videos such as the avata.
Can anyone explain why.
