C300 MK II - Can not write on SD card

Schocomike

Hello everyone,

is there a special feature that must be activated when recording on a SD card? I tried 3 different types and sizes of cards. All of them can be initialized, but none of them were recording footage.

Any ideas on that issue?

Thanks!

What specific brand cards are you using along with their specifications?  Are you using CFast or SD cards?

Did you initialize the cards in the C300 or via something else?  If something else, did you format to ExFAT?

Hey Ricky,

I tried Kingston 128GB an two SanDisk 128GB and 64GB, each different speeds. Will receive my CFast next week and use it then. I initialized the SD in the camera, which probably is the best way, but I will try formatting as ExFat via my Mac tomorrow. Strange thing ...

Thanks!

What are the specifics of the cards though? e.g. are these UHS-I or UHS-II? If provided, what is the "V" rating (e.g. V30, V60, V90)?

It may be that your cards are too slow?

Whiz, thanks for the link, I will take a closer look to that. But the "Clips" folder on each card is completely empty. If the camera would record proxies, it should leave at least some data in the folder?!
