Not sure if you have come across this before; Drone has been filming fine no problem, done the updates, Ummm what a pain in the head that was, P3A controller would not except the update but it sort of worked in the end. says have the latest firmware, then another time it say updates required, then 10 mins later it says it has latest updates. This drone is on drugs! Anyway, I was playing with course lock, took it off on an adventure 2400 meters and done some film, changed format to MP4 from the .mov Anyway got back took the film off the flash card. and it played about 30 seconds and froze. film kept going but picture just stopped. Tried every I have to get it to play, NOP nothing. But, looked on the android where it has a copy of it, and it plays perfect. WHAT!!! checked VLC player, and others some say no codec, what for MP4 ? it does. So something screwy is on the go. Went out and attempted another one ( film), same thing, But tried it Sony Vegas played OK, but the first film shot still will not play on my big computer. Have you come across this type, messed up reality before ???
