With such a short clip and watching it on a phone it's very difficult to see what you're talking about.

I'm going to take a wild guess and say that you were recording at 1080/60 or 96 though and what you're seeing is a result of the resampling method employed by DJI. It results in huge amounts of aliaising making the video look like crap.

30FPS is where it's at. Don't bother with anything higher,  it's simply not usable.

Hmm...same one I use for my 4K camera. I did notice something similiar on my camera (not my drone as it hasn't shipped) when I don't have the right settings this type of pixelation occurs. Could be the processing of the image as my 4K m34 camera has the same data rate of 60Mbs in 4K. Thought it could be the memory card causing this, guess not. Hope reformatting helps though.

I'm having the same problem with footage copied straight from SD card to high end laptops built in SSD drive which reveals artifacts, pixelated, stutters and breaks up randomly during playback on latest 2016 2.7GHZ 15inch MacBook ProT  (Touch Bar) with Phantom 4 latest firmware version 1.2.602, stock 16GB Panasonic Micro SD HC I Class 10 [3], 32GB SanDisk Ultra Micro SD HC I Class 10 [UHS 3] and 64GB Lexar 633X Micro SD XC I Class 10 [UHS 3] filming with stock settings such as Video format MOV, NTSC, White Balance Auto, Style None, Color None and several Video Sizes 4K 4096x2160 @ 24fps, 4K 3840x2160 @ 30fps and 2K 2704x2160 @ 30fps. I plan to step back P4 firmware until the problem is no longer present as It was not an issue in v1.1301 or v1.1.410... As I just recently made the jump straight to v  1.2.602..
