I have a Mini 3 Pro. I flew it 4 times today. No problem on the first 3 flights.  On the 4th flight, I did a "Quickshots" using the "Helix" mode like I've done a number of times.  This time, when I viewed the footage back home there is a visible rippling in the video.  I've tried to edit to show this here.

I checked the props and I "think" they look good.  Not sure how normal is supposed to look for sure in terms of balance.  The props all look in good order as does the gimbal.

I re-calibrated the gymbal and that did not seem to have an impact.  Anything else I shoudl check?

Thank you.

I uploaded the video, twice, but I'm not seeing here.  Just some writing in what appears to be Chinese...?

Hello. Sorry about the inconvenience. Can you please follow the steps below? (Feel free to skip steps already applied):
1. Check whether the aircraft has been collided. If the gimbal becomes shaky after collision, please send it back to DJI for diagnosis.
2. Make sure to remove the gimbal protector first before powering on the aircraft to prevent the gimbal motor from being stuck, or the gimbal will become shaky.
3. Please make sure that the gimbal is in Follow mode. If it is set to FPV mode, the gimbal view will be tilted when the aircraft tilts.
4. Please check whether the aircraft is in Sports mode (S-mode) when the gimbal becomes shaky. In S-mode, greater emphasis is placed on flight performance. During flight, when the aircraft attitude is too large, the gimbal attitude stabilization cannot be guaranteed. If the gimbal is shaky in S-mode only, which is normal, please switch the flight mode of the aircraft to Normal mode (N-mode) or Cine mode (C-mode) to achieve a more stable view.
5. Please check whether the wind was strong in the flight environment. If the wind is too strong, the aircraft will vibrate, resulting in the image transmission screen being shaky. We recommend that you test the gimbal in a windless or breezy environment. (Check the local weather forecast to determine the wind velocity. If the wind is too strong, the app will issue a wind warning.)
6. Have you ever adjusted the EXP value of the aircraft? EXP refers to the drone's exponential. The higher the EXP value, the higher the aircraft response sensitivity, indicating that the aircraft will respond flexibly to small stick movement. If you have ever adjusted the EXP value, please go to [Control -> Gain & Expo Tuning] in the app, reset the parameters, and then test the aircraft again.
7. Please perform gimbal calibration in the app. Using with DJI Fly: [Settings -> Control -> Gimbal Calibration].
8. After the above troubleshooting steps have been tried, it is preliminarily determined that the issue is caused by a hardware error. Please apply for an Online Repair Request and send the aircraft back to DJI for further diagnosis. You can use the following link to submit a repair request: https://repair.dji.com/
I hope this helps. Please keep us posted if you have further concerns. Have a great day ahead.

I see the video, same for me in Hyperlapse at least once. Windy? If not, well, not sure what to say

This looks a lot like props that are not in balance.
Often you can't even see that because they are just slightly bent.
Best to try replacing all 4 and see if the problem persists.
