When using my 5.5” Crystalsky with either my Mavic Pro or Mavic Air I get significant macro blocking when I replay the video on the CS.
The same videos are perfect when replayed from the micro SD card in the aircraft onto my laptop or TV.
All firmware is up to date on all devices.
Any ideas please?
Could it be the cable not being fast enough speed between the CS and remote ? (I have tried 3 but not sure if they are USB 3.1)

Hey Auspete, just to verify, are you replaying the video in DJI GO 4, right? May I know what's the video resolution?

Hi   Susan
Yes - I’m using DJI Go 4. Videos taken at 1920x1080 at 25fps. Just reiterating they are only macrblocking thru the CS not when the micro SD card is played back externally
Thanks

Hello DJI Susan (or anyone else)
Have you got any ideas how to fix my problem.
This is how videos look that are saved to the Crystalskys internal memory. The video saved on the Mavics SD card is perfect. Videos saved directly to my iPhone do not have this problem.

Crickets from DJI from the previous post...  

Has video macroblocking existed from start (first time you used CS with GO-4)?  Or has video macroblocking only recently started?
