I was at the beach a month ago and I wanted to record the sunrise with my H3plusBE and I thought it was recording the entire time but when i went back to look at the footage it was in clips of about 17.5 minutes and there ended up being about 6 of them for the bit over an hour that i was there. I was using the SanDisk extreme 32gb card recommended on the gopro.com website on their page. I have recently heard of issues that have occurred with writing speeds. If you know of a kick ass microsd card for the gopro h3plusBE that could carry on to the H4BE and record long trips and 4k footage please let me know. I would also like to start using the loop function and have heard issues with 64gb cards. Please Help!!!!
