I just purchased the Hero 4 Silver last night and purchased a 32GB 80MBs MicroSD for it. I did a test afterwards to ensure it would record at least 2 hours of video and I found with 1080S at 60fps it would record about 2h13m. It created (7) 4GB files and (1) 3+ GB file. I set it up for a class we were given today and while setting it up, I realized the FOV was too wide and the 1080S wouldn't allow me to change it. So I bumped it down to 1080P with 60fps and changed the FOV to Medium. I hit record and thought everything was working. I was sitting behind the camera and it was blinking the red light the whole time. After class, I stopped the recording, then went to play it back and noticed there was only 1 file, 4GB, 17m long video. It seems it stopped after the first 4GB. I've not seen any settings that say to span or not and my test with a different res showed it would span, so I'm a bit confused. Is this a limitation of the Medium and possibly Narrow view? Anyone else have this issue?
