Anyone having frame skips/lags with the extreme card?  I was shooting 4k 30fps and am getting a skip about every 5 seconds.  Ruined a lot of concert footage.  Anyone have this problem??  Thx  Bolton

Reformat the card in the Pocket.  A persistent problem with memory cards is the number of fakes there are around - let's hope that's not the problem.

Hi, we're sorry for the inconvenience. I would recommend reformatting the SD card to see if there will be changes, however, save the important files prior to reformat the card. For additional information, It’s recommended to use:
Samsung EVO Plus 32GB UHS-1 MicroSDHC,
Samsung Pro 64GB UHS-3 MicroSDXC,
Samsung Pro Endurance 64GB UHS-1 MicroSDXC,
Samsung Evo Plus 64GB UHS-3 MicroSDXC,
Sandisk Extreme 16/32GB UHS-3 MicroSDHC,
Sandisk Extreme Plus 128GB V30 A1 UHS-3 MicroSDXC,
Sandisk Extreme Pro 64GB V30 A1 UHS-3 MicroSDXC,
Lexar 633X 32GB UHS-1 MicroSDHC,
or a microSD card with a minimum write speed of over 30MB/s.

No, I haven't as of yet, though I've only done several test recordings at 4K@30fps.  The format media is Sandisk Extreme Plus 128GB V30 A1 UHS-3 MicroSDXC.

I'm asking about just the 'extreme' only.  No 'plus' or 'pro'
