Go Pro Black 3+ (How to Fix).

[Lonewolf]

Cards are even more exclusive / expensive for 4k cameras (GoPro 4?) due to the high write speeds required.

Andy, the Go pro 3+ Black will already record in 2.7K & 4K.
$229 for that card, that's not actually that bad a price, but from what it says it is not suitable necessarily for the Go Pro and wont actually be as fast as a UHS1 card with the G-Pro.

Sorry, I was reading supposed spec. of Go Pro Hero 4 (which has 4k at 30fps) article made 4k sound like a new feature as there are not many 4k action cameras http://dgise.com/post/62262921573/gopro-hero-4-specs-and-release-date-are-disclosed .

What next? GoPro 5 ??  bit of Apple Marketing going on here maybe...

Ive had several cameras and the annoying thing is that my crapiest cheapest one is still working great and the dear ones are playing up with corrupt files, but I have got into these forums and the common thing is everyone is saying memory card quality. so gone for

I take some comfort in knowing its not only my frustrating corrupt file cameras and are so thankful for forum members research

Issue is high spec. cameras with 120 fps, 4k and "Protune" require SD cards with high write speeds. Cheaper 1080p 30 fps action cameras usually manage with mid range SD cards.

Guy in youtube video was trying to use a Sandisk Ultra which is a class 10 card but only works up to 30 MB/s. He swapped to top of range Extreme Pro which works up to 95MB/s !!
