Check your settings and make sure you’ve not got FPV style selected, the gimble should then compensate for the sideways movement, as long as it’s not too windy
You could always try quick shots for smoothness then add in with your video/clips if when editing etc, thought id mention it just incase you wasn’t sure,
Your drone has this option as mentioned in the video below by @ianinlondon
I think it’s a case of being very gentle & smooth on the sticks, try sticking it into tripod/cinematic mode and practise, practice, practice. I keep trying and thought I,m getting better still some noticeable jerkiness. I’m using a mini 2se which is even more basic.
