I've transferred the original video to engineers again, thanks for your supporting!

Dear Natalia, could you please check my videos too? I submit two videos recorded at 4K/60fps where you can see clearly the jerk issue. Both videos are taken directly from the SD card without any editing.

**** The posts are shielded ****

And now, time for testing. Let's check if the video jerk issue has been resolved with the new firmware update.

Best thing to do is a trial playback before you buy. 4K video is very demanding.

Once I have some results from testing I will let you know.

Anything with an i5 processor is too slow.

Any news on the jerk issue, has it been fixed with the new firmware?

Can someone from DJI confirm if the dropped and corrupt frame problem is a hardware issue or a firmware problem? So that owners can send their craft away to get replaced or wait months for a fix.

Dear Natalia,

Finally we receive the latest firmware upgrade, the one which we have been expecting very patiently.

UNFORTUNETELY, THE ISSUE WITH THE VIDEO JERK HAS NOT BEEN RESOLVED, although we have been ensured from DJI that the issue had been rectified with the new firmware.
I have tested it again at 4K-60fps and the Jerk is happening again - very disappointed.

Please give us an official position of DJI about this issue.

I sent my P4P to DJI and they replaced the unit with another for this problem and a long list of other issues. The new unit is 90% better but I still have seen dropped frames. I have a ugly feeling that this is a hardware problem.....

Sorry to hear about that, could you please upload an original video for us? I can inform our engineers about your feedback.

Yes definitely, dear Natalia, you can download and watch the video.
At the instances 16s and 27s a delayed frame is added in the stream, causing the Jerk. This is checked frame by frame, and has nothing to do with the speed of playback machine or the video card.
Kindly waiting for your response ...

Jerk at 16s and 27s

Please can you let me know what is going on with the gimbal jerk issue ? Its still there after the upgrade , have you found a fix yet or shall i return my drone ? i have had enough now . just want a clear answer please .

The clear answer from users is: NO
The clear answer from DJI is: ???

Have the engineers come out with a diagnosis about frame jerk?

Natalia please could we have an answer on the gimbal jewel issue when shooting at 4k 6ofps ?
I really would like to know what to do now ? I have been very patient .

If its any conciliation I have a Phantom 2 that is still waiting on the promised stop/start function to the Go Pro. I bought it for this reason...guess what...that function never came ha

Natalia,

I have been reading and monitoring this forum for weeks crossing my fingers that the update would fix this issue as Im sure many others have. You and your team have promised the fix in the update. After updating, my aircraft STILL HAS THE PROBLEM. This is UNEXCEPTABLE for a $1500 drone. What is most sickening is that you are trying to sweep the problem under the rug like it is an isolated incident...

So, I have a phantom 4 pro that I use for paid gigs. Please tell me what I am to say to my client after delivering the raw footage with a frame jerk in it? Will you be giving my client a refund?

Has anybody any answer from DJI about this issue?

Yesterday we tested the new firmware on another 4pro, the same results: jerk frame 4k60fps.......

Natalie or somebody from DJI can i have an answer please ? This has been going on for way to long now ! This is NOT an isolated incident and i fear with the release of the P5 we will just be forgotten .
I am not letting this rest , shall i return my drone as i am not accepting this !
4K @ 60FPS is useless with the jerk

Dear DJI, just see that most of the threads in this forum have less than 300 views, but THIS specific thread (JERK ISSUE) has over 3200 views - does it mean something?

Natalia, yet another day filming with this issue. I have clients that hire me because I can deliver 4K 60. This is not right that we have to put up with being sold a drone that can't do what it was advertised to do!

I've reported all your feedback to our engineers, they are working on testing the firmware recently, if everything goes smoothly, a new firmware will be released in near future to fix this issue.
Thanks for your supporting.

The firmware is still in testing and will be released in the near future. Thank you for your patience.

If this is a firmware issue then why did I just talk to a support member and get told to return my aircraft???

Also just spoke with a rep and they said its a problem with the drone itself. Here is a recording of the conversation:

Excellent, total inconsistency. Does this mean that we all of us return our drones to DJI?

Thanks god i live in Germany so i have some month where i can wait. The first 6 month are a manufacturer failure if something is happening so i hope that DJI will solve the problem fast, i saw the jerk too and was very disapointed to have such issues on a 1700 € drone..... + extra batteries etc.....

I did send my 3rd p4pro back about 3 weeks ago. (Gimbal issues) It was the only one which didn't have the jerk issue. So I'm pretty sure it's a hardware related issue, than a firmware.  

Frame by frame of the Phantom 4 Pro gimbal jerk. Frames 1-5 are normal and the jerk is frames 6-7. Frames 8,9,10 are normal. Notice the treeline move in the opposite direction. This is not a card issure,it's a gimbal issue.

If you think that this is a gimbal (hardware) issue, why do we see the jerk only at 4K-60fps?

Do the DJI engineers confirm that the Jerk issue is firmware matter and not a hardware problem?

If this is gimbal hardware issue we need to return the P4P ASAP since the gimbal is only 6 months warranty, DJI please confirm many thanks.
