Wobbly Video

On my 1st flight, out of the box, I had these wobbly/jelly fringe edges type video effects.
The only adjustments I made were on the gimbal pitch,smoothness and the extra tilt up option.
I found the video was set to 1920x1080 at 30ps after loading the file. [Guess they all ship that way]
I have never had this type video on any of my DJI drones [even my spark] as I have 3 others, including MPro and M2Z.
Quite disappointing after seeing tons of other good, solid, videos from many u-tubers.
The card I am using is an Samsung 64mb Pro Plus U3 - formatted exFat
New firmware installed on activation also - v01.00.0200
Mode was "C" on app with no more than 7 mph tail-wind and no gusts.
Phone - iphone 6+ [dedicated drone phone]
PC - Windows 7 Pro - i7 core 3930K - 3.2 ghz / Video NVIDIA GTX 570

Anyone experience these video effects?
Snippet of that flight link attached ... Mavic Mini a.mp4
any ideas?

Does it have a filter on it? Some fliters restrict the motion of the camera.
Don't change the tilt up either just leave it on std.

No filter installed. I’ve seen several videos using the extra 20 degrees up (Drone Valley, etc) with no problems though. I’ll do another flight and closer inspection of the gimbal before I return it. The gimbal start up looks very fluid too. Thanks for your feedback.

Are you talking about Dji Spark here?
Never seen such footage from my Spark drone?
Some will claim this issue is either faulty sw/hw or imbalanced propellers.
Examine all props..

This is a Mavic Mini. I looked at the props [I'll check closer though].
I haven't tried a different SD micro; also I haven't had problems
with the [better] Samsung cards. After checking the props further,
I'll slip in my Spark micro card, that has been used without any problem.
Since the mini props are individually attached, I'm not sure how I could check
balance on them, plus they are right out the box, but (I know) defects do occur.
I really appreciate your feedback. I will post anything I find [hopefully a solution or cause].
I sorta of suspect the micro card, now that I think about it.

[Inclement weather, here in Texas, prevents any test flight presently.]

Lots of jello, looks like a defective unit but another flight or two when you're able should tell more. You mentioned about a tailwind ~7mph and being in C mode which has a max speed of 9mph. Probably a stretch but maybe a case of the craft fighting to keep under it's max mode speed if full pitch forward at the time.

Interesting idea ... I'll try some tests with that in mind ... rain,rain, go away!

UPDATE: I did a short flight earlier today, after switching
to another micro card, which is a 32 gb card. The card that
I used originally was a 64gb (listed in my original post above)
This flight was good, as I didn’t see the jello effect.
However, I only had time for a short test, so I’ll do
a longer flight soon, using other modes, speed, etc.
[test was done in “P” today]. I downloaded the video to my ipad,
so I still need to see the results on my large monitor, to check for
any glitches I might be missing on my ipad.

Summary (so far) seems the 64gb card is defective (dirty volume).

Regardless, got bad video - switch out for know good microSD.
