What is the Micro SD card specs on the card? It might not be that but it would be good to eliminate the card.I will try some other sd cards but this has always been a problem with the h. No problems with the bebop 2 but the drone plugs into the back of the mac. I am also camera dumb and never will be at the level you folks are at but I haven't given up hope.
If the video has artifacting....in other words a signal that looks like it is sometimes scrambled and jumpy, it is your system. Record at a resolution that is less than 4K as your system most likely can not handle 4K. You can run it through VLC media player and slow it down, that should confirm it is your system. As @Steve Carr said, "1920 x 1080 at 24 fps ". work your way up to a resolution your system can handle and then you will know your working parameters.Why do my videos go at slo speed on my computer
Time for a new computer if your system is being that badly compromised, I've only used VLC to sort out corrupted or damaged files, and demonstrations. VLC was one of the the few which my AV doesn't block.
