I know this is better suited for the gopro forums but I dont want to sign up for another forum to waste time on when maybe someone has insight here. Anyways bought a hero 3 black during the best buy black friday deal for 249. Hooked it up out of the box to my phantom and at 1080/60fps shot some beautiful footage. A few days later I did the firmware update and the footage is now choppy. I even bought an ultra speed class 10+ micro sd to make that wasnt causing the problem. The only thing different in the course of a few days is the update. Any thoughts?
