New to the forums.
I have the 3 black and use it in my car quite often. I have found that when playing back on iMovie, mine has a crackle. I did the update yesterday to the newest version and its still there. Considering the price of GoPro's I would of expected better quality. I definitely seems to be when the car is moving as when stood still, theres nothing but silence, but as soon as I move, the crackling starts. Radio is ofin the car so it wouldnt be that. I have tried different type of cases and nothing helps.
