Has anyone had issues with their Gopro Hero 3 Black with the video lagging behind the sound? I have done some research, and found that apparently if you don't have the correct micro card in the camera, this can happen. I checked mine and I have the correct '10 speed' or which ever. Also found that apparently if you film in real high quality, unless you have a powerful computer to play it back on, you can get this lag? Just curious whether anyone else has noticed it on theirs, and or fixed the problem or knows the cause?
