The SD card will not be the cause of your problem. It cannot record choppy or jerky footage, if it is not fast enough for the job it simply stops recording.  It is not possible to skip frames..

The most likely cause is that your computer is not fast enough to handle 4K at 60 fps. The truth is, not many computers can.

I posted 6days ago a link with my video clip and no answer so please DJI, can you kindly answer. Do I need to send my unit back or not?

I'm using latest firmware. Tried two different memory cards and the problem is the same.

Do you have news of this problem?

Reporting in, my P4P is doing the same. In my clips it is a single frame from earlier in the video (roughly 7 frames earlier). Definitely has nothing to do with the gimbal. Ruins the clip essentially as you lose the frame that it replaces. Would love to hear an answer on this or if DJI will repair my drone when/if they figure out the problem, seems to be an issue affecting a large number of P4P's.

If you want an answer to something, then ytou need to reply to a post by one of the DJI representatives, otherwise it does not come to their attention.

Would you please try again to upload to a dropbox without edition? thanks.

Do you have news of this problem?

I returned my drone to the dealer, since i didn´t get any answer from DJI. I immediately received a third P4Pro.

This is an UPDATE for my third one:

My first short test flight with my 3rd one was inside my studio. I tested 4K 60FPS and very first clip was ruined, because the gimbal made a sudden very fast movement. This happened when i was panning from left to right.

After that when the weather was a little bit better, i went outside a did 3 test flight. All the clips were good from the first flight.
I had to do the IMU calibration after this flight. It told me to do.
Then i made the two other test flights with no problems.
I will keep testing.
However, the biggest problem is now that the drone doesn´t fly straight at all.

Dudes, I also have popping frame with P4Pro since my 1st recording (last Sunday) and here are a lot more P4Pro with same problem in Korea.

DJI said it will be fixed at Jan. firmware but it didn't work at all.

So currently I and my same-problem-owners are waiting next firmware and if it fails we may refund.

I have the same issues. Multiple frame rates and resolutions. Sometimes it is dropping a frame and it glitches when it tries to recover. I tested multiple cards, same intermittent issues. Sent mine in for warranty after 6 flights. NOT confident that DJI has a fix and will play the shipping game back and fourth until they come up with a firmware fix..... https://vimeo.com/197648449/3f480dc4ef

May I have your case number since you sent it in? thanks.

I say my problem again:
I have the same issue in 4K/60 and no problem in 4K/30, 2.7K/60 and 2.7K/30. Firmware is up to date.

Now I only shoot 4K/30, 4K/60 is absolutely crap!!

I have found this same jerking issue on two occasion shooting 4K at 60 FPS.  Both time when the aircraft is rotating.  Once to the left and once to the right.  Using a Sandisk Extreme sd card didn't solve the issue.  Changing the gimbal setting didn't solve the problem either.  I'm using a brand new 2016 15" MacBook Pro with I7, 16 gb of ram and a blazing fast 1TB internal SSD so processing power or slow disk shouldn't be the issue.  I then looked at every single frame and found that one frame actually went backward causing the jerk.  Cut out the frame and the video looks normal.  By the way I have the Plus with the built in screen and on the video stored in the controller it also had the jerk.  Can't say if it's the gimbal or the compression algorithm but haven't seen this jerk flying in a straight line.  Hope DJI and give us an answer soon.

Yes, I have the same problem with my P4P, and I checked the video frame by frame. I found that one frame actually went backward causing the jerk, at 4K 60fps. I don't think that the camera can move so fast (1/60s) and produce this erroneous frame, but on the other hand, DJI must reply with a clear position on this issue.

Something similar is happening to my P4 Pro quite a few times. However, the times I noticed it, it was associated with changing directions (like pushing the stick to the left while the bird was going right, etc.) Also, I tried to replicate  it when having the bird very low and close to me, so I can in a way 'visually inspect' what's going on. It looks to me that it's not the gimbal's fault; the whole bird is jerking when changing direction, and I'm guessing the gimbal just cannot follow this sudden vibration. Note that it happens in 4K/24p. I haven't tried 60p yet. It looks like that:



Obviously, this has nothing to do with either SD card (I have a  SanDisk Extreme Pro, perfectly able to handle 4K in high bitrates), neither with a dropped frame, as there is actual physical vibration.

Is that something common or should I return?

I can get something as minor as that movement on my P3P when I suddenly change direction, nothing unusual about that. But it is easily fixed, don't make sudden direction changes.

Thanks for sharing. What bothers me is that it happens randomly. After this video, I tried to do it several times and it perfectly smoothly transitioned from left to right and back.

When it happens, I can hear the engine roaring aggressively (I'm guessing trying to fight inertia) and probably this gives the vibration. I just wonder why it happens only randomly.

P4P problems are a horror story, and I just want to make sure nothing's wrong before Amazon's 30 days return deadline expires. I don't want to have to deal with DJI  for service again, I returned a DoA Mavic Pro two full weeks now and it still doesn't even show up as a progress indicator in my account, to keep track when I'll finally get a refund.

Great company, fantastic products, but it looks like there is a serious problem with both quality control and customer support.

I understand your concerns. But I would not count it as a defect. As I said, my P3P does something similar so I just don't make agressive moves when shooting. In fact I nearly always program my flights now to make them smoother.
