I'll be going on my first freediving trip in two weeks and I will be bringing my gopro hero3 black edition with me. I know that there is a thread about the hero3, but my inquiry is more about general frame rates. I read somewhere else that underwater, the faster the frame rate the better. So, this camera is capable of 2.7k at 30p, 1440 at 48p, 1080 at 60p and 720 at 120p. Many people were saying that if they could film 720 at 120p, they would, but I'm concerned about the low light capabilities of a high frame rate and this was before a high frame rate was conceivable above 720 with a small sports cam. I won't have much time in the water, which is why I'm hoping to get it right from the get go.
