[size=14.6667px]Hello![size=14.6667px]I just got my Mavic a few days ago.[size=14.6667px]I did all the calibration and firmware updates and then[size=14.6667px] shoot video with different resolution and frame rate.
[size=14.6667px]But all video have a ripple and jitter. You can see it below.


Does anyone know how to fix this problem?
Support offered to replace the drone. But they have not seen the video.
How do you think, is this a problem covered by the warranty?

You mean the bad moire on the buildings? Upload the original video to dropbox, I can take a look for you. I have a couple of 4k rigs here. It might be post processing in whatever program you use.

I also am not seeing any jitter. Just moire on the buildings.  In my case shooting at the 3820 (or 2.7k) resolution with 30 fps improved things. I would give that a try.  (Note, I only very rarely fly around buildings)

If you shot at 1080 above 30fps then this is an expected and normal limitation of the camera stack.

Yes, maybe it's moire.
I uploaded original video  https://drive.google.com/open?id=0BzOf4SiuJR2LdVpzQnhJbGNXb1U
But this video is very huge (4Gb because of 96fps).
Also I uploaded a small another video (4K 30fps) with the same problem to dropbox https://www.dropbox.com/s/y2nrfatscuu0t83/DJI_0012.MOV?dl=0.
Pay attention to the window of the red house on the 24th second.

This is not good if such a restriction is present.
Sometimes I need to capture a video with >30fps for making slow motion.

I was going to download it, but you said it's 96fps? That's a known problem with the mavic. Fps over 30 has this issue, it's explained really well in a couple of threads. Basically end up with a lot of aliasing over 30 fps. Let me find the thread on that.

The 4k 30, I'll take a look at.

Edit- Saw the one white building had a bit of shimmer on the edge, but I think that's normal when at high shutter speeds. I'm on a 4k monitor turned down to 30 fps so I'm seeing it as is. The thing too, your panning way too fast. Noticed the auto shutter can't even keep up. You can see it compensate from low to high like when you aim at the ground suddenly. It looks like a mask of artifacts briefly applied. I noticed in my own tests, this is what happens when the shutter is set too low for the scene.

All down to flying correctly. Nothing wrong. Slow the gimbal and yaw speeds when filming or try the cinematic mode.

Yup. I'd have preferred that DJI mention the qualitative difference in >30fps 1080 in the specs, but confess I'm mostly interested in shooting at higher res, anyway. You might be able to get away with 60/96fps with content lacking lots of straight lines where the aliasing becomes obvious.

Thank you, guys!
I figured out the problem.
Changed the settings. I lowered the rate to 30 fps. Lowered sharpness and contrast.
Lowered the shutter speed by attaching the ND filter.
It became much better.
Spasibo!
