5D III stop recording
« on: August 01, 2017, 11:36:42 PM »
Hello everybody,

I'm getting some trouble to record without getting the record to stop.
I have this SD card :
formated ExFat
and also this second card :

And if I want to go above 1080p, it's telling me that the card is not fast enough "it has to be 160mb/s". This is telling me this even if I switch on recording on the SD card or the CompactFlash.
But I don't really understand because my SD card goes up to 300mb/s and the other card goes 160mb/s.

My point is to try to film 4K raw. Am I not doing the right process?
Let me know if you need more informations about my settings.

The internal SD bus is the limitation. Use a fast CF card instead.

Internal SD-card interface 5D3 is - at time of writing - limited to about 24 MeByte/s (theoretical Bandwidth) and it's incompatible with UHS-II. UHS-II card will work in UHS-I mode and the only time you will see it running beyond 24 MByte/s is outside the cam with a decent cardreader.

For 4k recording you will have to switch to experimental builds: Top of page -> Downloads -> Downloads (Top down menu) -> Experiments.

hi Guys,
thanks for the reply. Then what card do you recommend?

Also, I still get the record to stop when I try to record on 1080p 30fps RAW. Is this should normally not happen at this resolution, right?
