Halo, I have had this issue a few times and can't figure out why: I use litchi for 18 mins aprox flights and I use auto recording function at 1080p 30 fps or 4K somethimes. My card is 64gb sandisk extreme pro so it's fast enough and exfat format. So speed or format is not the issue. It will record for about 10 mins then will stop and start recording again. Any ideas why?
