Welcome to the forum.
I see what you mean about the video. That's not good at all.
I looked at your other videos uploaded to YT over the previous 3 weeks and I don't see the same jello like waviness.
Has something changed with your gimbal/camera recently? Are you using only 2 anti-drop pins? Are your white vibration dampeners intact and in place? Is the small piece of shipping foam removed from behind your gimbal? What were your settings for that video?
@alokbhargava, Alok, you'll see it clearly when you watch it on a monitor
