This is a big problem with Mavic 2, and as slow as the camera rotates, this effect appears. At Phantom 4 Pro is resolved with 50(60)P

Ok, that does eliminate the fast shutterspeed.

It is possible that there is a problem that the monitor is refresh 60 Hz, so there is a desynchronization

I must say I don't see any flickering.
Is there a specific place in the frame you see it best?

It's not a flicker, it's a judder, it also comes up to the camera when it is shot at 24p

Sorry, I mean 'stutter' not flicker.
I don't see stuttering in the video.

I had the same problem with my 2 Pro. Ended up being my SD card. Now seems everything is okay. Just a thought.

I also think that the SD card can make the problem. when I turn on Cache Video Shooting ,the drop frame appears.

Belgrade, Serbia. This example is seen even better. But everything broke the judder at the church clock

Yes, that's what I'm talking about, but it does not matter with the SD card. Here's how it looks with the Phantom 4 Pro, totally different:

I'm having the same issue, and found that the closer subject related to camera, the worse it appears.
The easiest way is to hover over a building, point camera straight down, and fly in any direction. As the camera is quite close to the building, but building moves relatively quick to camera, the judder will be really bad.

To find out what's causing the judder, I have tried different combination of H264/H265, 24P/30P, Nornal/HQ, and shutter speed from 1/50 to 1/800. But all of them will have judder problem.

Hi DJI Admin, could you take a look at this issue?
