Yesterday I received a replacement of my P4 pro.  The replacement drone still has a problem with the video, and this problem is common to many costumers. I recorded 4k 60 fps videos, the problem is shown with any micro sd card (Sony Dji original, Sandisk extreme pro, Samsung pro). I bought this drone to have a better quality in video recording as advertised by Dji, but the videos are unserviceable. I waited one month to have a replacement of the previous drone because Dji didn’t have any item in stock, and now I have again a drone that doesn’t work as it should and I am loosing clients because I can’t record videos and work with them. The question is: does Dji have P4 pro with no problems? I ask for a refund or a replacement (DOA) with a new product with no problems and within the expected time (5 working days) I own other 4k cameras, osmo mobile and a P4 and the videos are perfect with no flaws. iMac (Retina 5K, 27 pollici, Late 2015) 4 GHz Intel Core i7 32 GB DDR3 a 1867 MHz AMD Radeon R9 M395X 4096 MB Internal SSD 1 Tera
P4 pro Last Firmware

I remain waiting for a kind reply, regards,

Fans_Drone...  thats terrible.  Sorry to hear you are having this problem.  Question, does the problem occur at lower resolutions?

The P4 has had a longstanding problem (different than the one you showed) of becoming very pixillated if shooting at full 4k and either flying at low altitude (since so much more detail is required to be captured) or when doing faster gimbal tilts up or down... sometimes just too much information is being processed.  I'm wondering if the P4P has a similar problem but it just shows up as dropped frames?

Anyway, curious to know if this occurs at lower resolutions than full 4K?  Also curious to know if this problem occurs when flying at higher altitude?

And finally, whats up with the horizon on your drone?  Terrible.  Have you calibrated the IMU, Gimbal, compass, etc?

I don’t have testing p4 pro at low resolutions, i need a video 4k 60 fps for my works, at higher altitude is the same; check my video of the first p4pro.

Cold imu, gimball etc, latest firmware, but with the previous firmware is the same

thanks for your concern

Two things.. What wrapper are you using.. .mov or .mp4?  Is it safe to assume you're using auto exposure settings?  

If 60FPS isn't absolutely necessary, I'd consider going H.265 4k 30fps and look at how stunning the detail is.  H265 can take color correction like  a champ as well.  Either way, it might be worth testing -- just to see if you have the same frame dropping and ghosting issues.  I'd also go with the .mov wrapper vs mp4.  Let us know how it goes.

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.....

I would love to look at your original footage, but I refuse to join some file transfer service in order to do so. Most people here use Dropbaox, which does not make any demands on the user.

Mp4 or Mov is the same for the jerk problem.
I use 60 fps because the videos are more flowing.
I use final cut and h265 isn't supported without encoding

I forgot to suggest trying manual mode, to see if the issue might be related to exposure settings changing (albeit unlikely) just trying to help isolate the issue.
