but also a major problem with GoPro seems to me to be the completely immature support and incompetent employees. I had, as recommended by GoPro, my SanDisk 32 GB Class 10 card purchased. However, I had constantly sudden crashes in the middle of recording. even when image series partially. after countless call at GoPro was always referred defective to an apparent end. even a Class 10 Transcend card I bought to test. but always the same.
after I was xte times at GoPro phoned someone seems to be part of the management of more idea than the others had. after I, as also previously always, my problem had described exactly, I was told that the Class 10 cards only meet the minimum requirements !!!
to exploit the full potential of the device but you have better cards than the SanDisk SDHC Ultra share grab. because the create just under 30 MB / s write (according to SanDisk Data Sheet).
video recording at ProTUNE need at least one map, the writing speed of 45MB / s support.
That would be about the SanDisk Extreme Pro cards (write rates up to 90 MB / s - actually too fast) or, for example, the Transcend Ultimate cards (write rate up to 45MB / s - what the Hero3 BE required).
I myself have bought me transcend the test and now I have not had a crash. So what GoPro thereby presenting slow cards for a high end device recommended is already questionable.
otherwise I can but tell of nothing really negative. I got me the battery Backpack bought separately to be able to record longer without interruption. with my current 16 GB card and 2.7 k I manage just 1 hour I would say. the battery would probably also take part in a 2 hour recording.
I can image series with Backpack record up to 3.5 hours. So the resistence on making it bigger than my HERO2. you can also buy a cheap battery, there should be minutes longer recording time probably still 10-20.
killed as a sum, I am now very happy with the camera; So who should strike interess definitely! may convert you so still and Amazon's very accommodating.
