We have decided to take a closer look at GoPro Hero 3 Micro SD Recording Times I have had a GoPro Hero 3 Silver and Black editions for almost a year. Over that time I have been keeping a log and have recorded the approximate recording time achieved from full battery charges and with particular SD cards.
1080p (30 fps): 4h 21m
960p (30 fps): 5h 26m
720p (60 fps): 4h 21
720p (30 fps): 8h 09m
WVGA (60 fps): 8h 09m
I have a number of other settings to try out and will report the results. However GoPro appear to be pretty accurate with the figures. I was only a minute or two out in all cases.
On a day to day basis I am now carrying a couple of batteries and a few 16gb or 32gb class 10 cards with the highest read/write possible. Most of my current cards have read/write speeds at 30MB/s. However if I were shooting at 2.7k or 4k then I would need cards with a much higher transfer rate such as the Sandisk Extreme Pro range or the new 633x Lexar cards.
The GoPro Hero 3 Black edition will chew through its battery faster than the silver edition with the same settings. I have ran two cameras under the same conditions on a number of occasions have always found this to be the case.
