I have my Hero4 Session for a while now, and it is an amazing camera. I have filmed a couple video's in my glider when flying and now I'm going to do a cross country flight of a couple hours, so I turned the resolution and framerate down from 1080p60 to 720p30, and found out I can still only record a maximum of 2h 38 minutes. I always use my powerbank to charge, but I never seem to be able to get more recording time out of a 32GB MicroSD card. In 1080p60, the memory card is completely full after 2 hours and 38 minutes, and in 720p30, it's completely full at the same time of 2 hours and 38 minutes. Am I doing something wrong? I have already tried a 64GB Samsung Evo Pro and 32GB Sandisk Extreme U3 MicroSD cards, both of which are full after 2 hours and 38 minutes of recording.
