GoPro DeTunes ProTune To 35mb/sec For


In the last firmware update for the Hero3 camera GoPro has disabled full 45mb/sec recording in 2.7K and 4K for most micro SD cards except for a very short list off ones they bless. This list includes :

  • Lexar 32GB SDHC 600x (LSDMI32GBSBNA600R)

  • Lexar 64GB SDXC 300x (LSDMI64GBBNL300R)



  • Samsung 64GB SDXC (MB-MGCGB/AM)

What ? If you don't own one of these cards then ProTune gets detuned to 35mb/sec. If you don't have the new firmware installed don't. In fact installing firmware on the Hero3 is such a huge hassle its probably almost not worth it, especially now with the downgrade. Its also possible that this downgrade was put into the second most recent firmware update as well.

Why ? I have no clue. One would guess that it would be because other cards aren't fast enough to be reliable, but that simply is not the case. I bought a Sandisc 64gb micro SD card, the SAME card GoPro themselves sold. It will record 45mb/itsec all until the battery quits. I put my micro SD card into a SD card adapter, put that into my laptop's SD card reader that is in the PCIe slot. BMD Speed test confirms : 10mbyte/sec write, 40mb/sec read. 45mbit = 5.65mbyte/sec or my card is about 2X fast enough. That is plenty of safety margin. So my open comment to GoPro is why ?

There are other brands of micro SD cards that are fast enough. Having this limited list makes no sense. Let the user determine if their media works or not, especially since my card worked fine before. 

I have in fact shot some video on my Sandisc card and they are 35mbit so this is for real. I'm considering starting an online petition to get GoPro to restore this functionality since we don't have something like Magic Lantern to do what we want. So what does everyone think ? start the online petition ?
