So I've been shooting at 2.7k Medium FOV on the GoPro Black 3+ and it's been pretty good at capturing crisp video and keeping the props and landing gear out of the frame. I have noticed though that at times with fast action shots I get stuttering. I just read that for 2.7k and 4k video though, you need the faster UHS-1 or greater Micro-SDXC card, not the Class-10 card. I just popped for one of these guys and I'm hoping it solves my problem: SanDisk Extreme Plus 64GB MicroSDXC UHS-I Memory Card Speed Up To 80Mb/s http://www.amazon.com/dp/B00DM1BDPK/ref=cm_sw_r_udp_awd_eH5ytb0NR2B1Z Anyone had experience with shooting 2.7k on this card? It's 80Mb/s vs the Class 10 10Mbp/s (I think). In any case I'll update on how it works out.
