I'm having this issue where there is are 28 frames that have this gray pixelation.  I "refreshed" my firmware the same day that I shot these last videos this happened on. This problem has been happening for weeks at this point. Any ideas on what the issues could be or how to fix them. Also, I can export a video if the gray pixelated frames are on the timeline, so I took a video with my phone.  

Hello. May you please re-send the video? It is not working or playing on our end. Thank you.

It was in private mode on youtube, but now it's on "unlisted" so it should work. Let me know if it does not.
Thanks for letting me know!

No-one can make an objective diagnosis of your issue from a video clip shot off the phone. Upload a small section of original camera footage to Dropbox, then come back and post a link to it. It should be uploaded from the video on the SD card in the aircraft.

That looks like file corruption.  What SD card are you using?  If you are shooting 4K, you need to make sure the SD card is fast enough to handle the bitrate.  Also, have you tried using a different SD card?
